I've cooked up a very brief analysis of Maxwell compared to Kepler. Maxwell employs a distinct set of improvements over Kepler. #1 Redesigned GPU clusters, control logic for each GPU cluster (SMM vs SMX) has been increased by 50%. Total number of CUDA cores per mm² went down by 20%. This improves performance per clock of each CUDA core & allows for more fine grained control. #2 Significantly larger L2 Cache (8X larger), this reduces the reliance of the GPU on using the dedicated GDDR5 and having to pass through the memory buss which both burns unnecessary energy & inflicts latency. This improves performance significantly in bandwidth constrained environments & significantly reduces power consumption. Performance analysis is based on data from Tom's Hardware review. Performance efficiency is based on data from PCPer's review. Non-bandwidth sensitive scenario. You can clearly see that this is not a bandwidth constrained scenario, because both the R7 265 & the R7 260X are performing exactly the same, both of these chips have pretty much have the same 1.9GFLOPS of compute performance with the main difference being that the R7 265 has 80% more bandwidth enabled through its larger 256bit memory buss. Balanced compute/bandwidth scenario. Here we see typical scaling between the R7 265 & the R7 260X which indicates that this is indeed a bandwidth-limited scenario. Average performance across all tested games. Performance boost per clock per mm² = 4.5% in non-bandwidth constrained environments. (AC4) Performance boost per clock per mm² = 9.7% in bandwidth constrained environments. (FC3) This tells us that at lest half of the performance per clock improvements come from the larger L2 cache. Die size per CUDA core went up exactly 20% compared to Kepler of the same die size. Performance per CUDA core improved by 29.5%. compared to Kepler of the same core count. Kepler allows for more CUDA cores in the same area as Maxwell, in this case performance per mm is more appropriate to compare both architectures. Total average performance improvement per clock per mm² = 7.9%. NOTE: All performance metrics were obtained by dividing the frame rates of the 750 TI over the frame-rates of the 650 Ti after adjusting clock speeds of both to match. Die size of the GTX 750 Ti is 147mm² , theoritical die size of a 650 TI can be obtained by dividing the GK104 die size which is 294mm² by two (this makes sense because GK104 has exactly twice as many functional units as the GTX 650 Ti in regards to CUDA core count, texture units & ROPs), giving us exactly 147mm² as well. Maxwell seems to operate at higher frequencies than most Keplers, barring from the 770 & the 760. It's not yet clear if this improvement is a direct result of the matured 28nm process or if the architecture itself has some positive influence on clock speeds.My guess is that it's likely a mix of both. Now to move towards performance efficiency. Average power while gaming. According to various power measurements the 750 Ti on average draws 62-64 watts while gaming. So we'll put it at 63 watts, this puts the 260X at 94 watts, the 265 at 104 watts, the 660 at 137 watts and the 650 ti at 74 watts. Keep in mind that average power consumption and TDP are actually quite different, TDP is Thermal Design Power and indicates how much heat the chip generates, while power consumption is the wattage the system is drawing at the wall. Most Kepler & AMD GCN cards don't actually reach their full TDP when gaming & only when stress testing or doing compute intensive workloads. Maxwell seems to be the first to break this trend, running almost always at its maximum TDP level, this indicates that Nvidia actually did a lot more work towards power management with Maxwell. So lets look at efficiency. We'll set the GTX 660 as the standard. Summary : Total average performance improvement per clock per mm² = 7.9%. Total efficiency improvement per FPS over Kepler = 42%. Ok so what does this mean ? this actually means that if Nvidia were to rebuild all of it's 28nm Kepler GPUs without increasing the chip sizes & keeping the clock speeds constant, you will see an average gain of 7.9% in performance.

So this week Nivida released their 750ti graphics card which packs a punch at its 150 dollar price range. The thing that amazes me is that there is no extra power needed. So with that said i thought, Maxwell in something like a Titan would be mind blowing! it could deliver almost 2x the profromance and still be low power consumption! I mean yeah you will still need to an extra power connecter, but not as much power would need to flow through for amazing profromance. So what do you guys think? Maxwell, does it sound awesome, how do you think it will turn out?

I am very new to water cooling but I want to hook up my own personal rig so my question: Is this a good pump reservoir combo or should I look somewere else? If you don't think that its a good product what do you think I should get then, also what would the price be? If you would like to look more closely at this product here is the amazon.com link: http://www.amazon.com/dp/B00A42X2KY/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=2IBMHK23KU580&coliid=I20CI5TKSPRICA. Thanks for all of the help you guys give me!

I am going back to PC master race. No I am not a pure console gamer, I just went overseas and not gaming on PC resulted to sadness. I really do feel that PC gaming is one of the missing links in my life now. My rig: i5-750 @ stock (planning to OC with Noctua U12 SE2 I think, I forgot the exact model #, targeting 4Ghz) 4GB DDR3 650W Corsair Bronze GT610 (GTS450 suddenly died, have to replace to be usable) 1080p only My choices: GTX 760 GTX 770 GTX 780 I can afford GTX 780 but I am reluctant if the CPU would bottleneck it, even OCd to 4Ghz. I want buttery smooth 60fps. Current games on my library are: SimCity (1 year beta tester now), Torchlight 1, Portal 2, and bunch of humble bundles. I want to play AAA titles in 60fps. Please give me your insights and suggestions. I am not familiar with AMD side. I heard that their current lineup are damn hot and noisy. I like the rig to be quiet. On the side note: what is a good TK mech keyboard, mx brown? Thanks!

GeForce 750 and 750ti have been released: http://www.nvidia.com/gtx-700-graphics-cards?m=gtx-750ti

Hello! I am new to building PCs and I would like your expert opinion and your advice. I was browsing between cards for my new PC and settled for an "ASUS GeForce GTX 760 DC2 OC" but now that I saw from Linus's video a new 750 card has come out (which is much cheaper) I was thinking of grabbing that one instead. This is where I want your help. For reference: (Prices converted from SEK to US-Dollars) ASUS GeForce GTX 760 DC2 OC 353,30$ (pricedropped to 307,01$) ASUS GeForce GTX 750 PH 1GB OC 192,69$ ASUS GeForce GTX 750 Ti 2GB PH 214,44$ ASUS GeForce GTX 750 Ti 2GB OC 231,26$ Questions: What does "OC", "Ti" and "PH" stand for and what do they do? Which card will perform better when used for games? Is the difference noticeable? Which one would you recommend performance-wise and economy-wise?

So after a couple of days of research i've made up my mind and i was going to buy a corsair RM 750w psu ( that costs around 110€). But now i have a problem... I can get an AX860i for 125€, only 15€ more when they usually cost which is around 210€ or maybe a bit more. Should i go for it? Is it worth the extra 15€? I don't need all that power now but maybe in the future, don't know yet. I was looking for a quiet system, is the AX alot louder than the RM? I know that the RM fan doesnt start until it reaches 40% load. Help me out guys ! Thanks alot!!

Firstly, Merry Christmas to all of you who actually do Christmas, I hope you have a wonderful time. I'm enquiring for my girlfriend (for some reason it's too much effort for her to actually register, something about wasting LoL time) who finally wants a desktop PC, and not just her laptop. We're planning to work together (she's going to help me edit my content) so being able to render footage, that has been quite intensely edited fairly fast is crucial. Also, gaming performance needs to be good. She's going to be running two screens, gaming on one, the other as a misc display. Preferred resolution is 1920x1080, with medium settings being the standard aim for most current titles (BF4, AC4, BioShock Infinite) Obviously, some more intense games can be lowered, but Medium with probably 2-4x FXAA. Fortunately or not, she's a big fan of the Define R4. She's already got it (my brother gave her his old one after he decided to move to a 750D), and it's the non windowed version. She also has an optical drive already, so those two are both removed from the budget. Peripherals are not included in the budget, just the PC itself. She'd like to prioritize quiet gameplay over airflow, but obviously neither of us want the thing melting. She's probably going to OC a bit (we're certainly going to try 4.0Ghz if we think the chip can do it) We intend to use the prebuilt fan controller, which can have up to three fans on it, with voltages of 12v, 7v and 5v. As she's going to use a card with GPU Boost 2.0, she will be using an intake/outake on the side of the case. She's going to remove the top HDD cage and put a intake fan in the topmost front intake (so that there's plenty of airflow through there.) Because her desk is short, and the case will be pretty close to it (vertically), there will also be an output fan at the back, although if need be we can remove one of the top ModuVent panels so that the heat can passively exhaust (would rather avoid this due to dust) Finally, here's the PCPartPicker UK breakdown (obviously, the Case and OD are not included in this list, read above if you skipped to see why) PCPartPicker part list / Price breakdown by merchant / Benchmarks CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor (£164.99 @ Aria PC) CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler (£23.98 @ Scan.co.uk) Motherboard: MSI Z87-G43 ATX LGA1150 Motherboard (£81.82 @ Aria PC) Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory (£60.62 @ Ebuyer) Video Card: EVGA GeForce GTX 760 2GB Video Card (£191.98 @ Dabs) Storage: Seagate Barracuda 2TB 7200RPM, 2x Seagate Barracuda 500GB 7200RPM, 1x WD Scorpio 250GB (These we located dotted around, not part of price) Case Fan: Noctua NF-F12 PWM 55.0 CFM 120mm Fan (£15.98 @ Amazon UK) Case Fan: Noctua NF-F12 PWM 55.0 CFM 120mm Fan (£15.98 @ Amazon UK) Case Fan: Noctua NF-A14 FLX 68.0 CFM 140mm Fan (£18.76 @ CCL Computers) Case Fan: Noctua NF-A14 FLX 68.0 CFM 140mm Fan (£18.76 @ CCL Computers) Case Fan: Noctua NF-A14 FLX 68.0 CFM 140mm Fan (£18.76 @ CCL Computers) Power Supply: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply (£58.09 @ Dabs) Operating System: Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit) (£72.12 @ CCL Computers) Total: £741.84 (Prices include shipping, taxes, and discounts when available.)

Just recently resurrected a old mobo of mine with a LGA 1156 socket on it. did some work and here are my specs. Mobo: Asus P7P55D CPU: i5 750 overclocked to 3.5GHz @ 1.3v GPU: 2x Asus GTX 560 TOP OC PSU: 700watt cheapo. Cooling: Thermaltake 760 Plus for CPU only, GPUs are on air. OS: on a 90Gb SSD from Corsair's Force 3 Series. Running Win 8.1 Ram: 3x2Gb Corsair XMS3 Reason: To Fold, hence why im in this forum section with it. Problems occurred: Broke my watertank on the 760plus, i stressed it too much during a cleaning i twisted it with the pump as leverage on accident. i had to reglue it back, now its soo sketchy having it live on tho... i dont want leaks. the MOBO and ram was used in AquaPC therfore was covered in oil. i managed to clean most of the oil. I also noticed one of my pins in the mobo socket was slightly bent up in the corner of the socket. after a gentle push with a small eye glass screw driver, it sadly well fell out. didnt even get it over to where it needed to be. but yes im still running with it. and for some reason even overclocked. i was simply surprised when the system even booted. I also realized, windows 8.1 Reads all 6Gb of ram, but states 2Gb usable, not sure how to correct this. Temps: Anywho thats my Folding Rig quick thread. wasn't gunna make a build log or anything. just figured ill post in the folding fourm to show what people can do with old hardware they are no longer using.

I'm getting a 750D For my new rig, And wanted to know if it could fit a h100i in it.

Any of these builds better than the other or have any problems? Amd Nvidia Build: http://pcpartpicker.com/p/1YNAb $725 Intel i3 Amd Build: http://pcpartpicker.com/p/1YNOB $725 Intel i5 Amd Build: http://pcpartpicker.com/p/1YNUR $790 I would like to use this thing for like at least 2 years or 3? Which one is worth buying?

Hi, guys. I'm upgrading my PC soon so I have a quick question for you. I built my rig back in 2012, everything is new exept for my old case from 2004. It has no cable managment options, terrible air flow (just bad) so I had no choice but to just throw everything in there and hope it works I was going to buy a new case soon, but I just didn't. Now it's time to upgrade it. Here's how my PC looks right now PC Specs: CPU Intel Core i5 3330 3.0Ghz Motherboard ASUS P8B75-M LE RAM Kingston HyperX B 4GB DDR3 (2x2GB) GPU ASUS HD7770 1GB GDDR5 Case Old unknown case Storage Seagate 465GB PSU Corsair CX600 600W Builder Series Display ASUS VS239HV IPS 24" FullHD Cooling 1 cheap 120mm fan Keyboard MS Office Keyboard Mouse MS mouse Sound on-board sonud card Paid it 860 USD (502 GBP). Note in my country (Croatia) tax on everything you buy is 25%. Now I'm thinking of buying Fractal Design ARC Mini R2 with some LED Corsair AF120.....i don't know, I'm still thinking. Back to the point. Since it's time to upgrade, and my HD7770 is pretty weak for today's games, I'm thinking of buying MSI GTX 750Ti Gaming Edition. I'm pretty sure it won't, but just to be sure, will my rig bottleneck my soon-to-be 750Ti? Thanks.

Specs are in the sig. All cores are running at 3.2 GHz @ 2.004V. Cores have been disabled; 1, 2, none respectively, with RealTemp recorded on all 4 cores, a maximum temp. of 70C. Should I be concerned regarding the 2.004V? It's cooled by a Rosewill RCX-Z90-CP with Arctic Cooling MX-4 thermal compound. It was tested with Geekbench 3.1 32-bit.

Here is my current (and old) rig: CPU: AMD Phenom 9550 RAM: 4GB MOBO: mATX Generic HP (Has only PCIe 1.0x16 ) GPU: 8800 GTS PSU: Corsair CX430w I was wondering if I would be able to throw in a GTX 750 ti and not have any bottleneck on the GPU? If there would be a large bottleneck, what would be a good GPU to get? I want to build a new system but I will have to wait a year so I need something to play most games decently till then. Thanks

Hello all, I recently bought an R9 270 card used, and was wondering, what the performance would be like compared to green team? I tried to find bench marks, but all I could find was it being compared to AMD, or the 600 series. Please and thank you for all of the help

Many people complained that the EVGA 750Ti FTW w/ ACX was too loud at idle even after the BIOS update revision fan control. I would be one that has to agree. Basically the issues comes down to the fact that fans it was spec'd with were too high RPM and that they can only go down to 42% since they are voltage controlled. Many people found that even with a max OC the card never needed to leave idle. Even the EVGA tech I talked to admitted to me that his never went above ~45%. This means that they could have easily spec'd the card with fans that say had 50% the max speed as the current ones and have been perfectly fine. With EVGA cards as long as yo ucan put it back in its shipped state (nothing modified on the card) you dont void the warranty. Since no one makes any after market coolers for the two maxwell cards I came up with a slight mod my self. I happed to have the slim 92mm noctua fan left from anothe fit and it seemed to be the perfect fit. I did all of this just by taking off the shroud and unplugging the old fans. You could actually fit two of the Noctua's in there and put the shroud back on. But only if you didnt mind voiding the warranty by doing a bit of dremeling. And no i did not put the shroud back on its just for demonstration purposes. Well tell me what you guys think. I know it not pretty but it in a HTPC where silence it paramount. Addition: Another cool thing you might like to know is that I actually had a adapter from noctua that allowed me to plug the fan directly into the GPU without making anything myself. Also many of you may not have seen these before since they are kinda old school but those black screws were very common in the past and actually screw into the fins on the heatsink. I probably scavenged them off motherboard or other device I scrapped.

Hello everyone! Its my first time to build a custom PC! Is the EVGA 500B 500w psu enough for a system running core i5 4460 & a palit gtx 750 ti stormx dual? if yes, will I be pushing it already? I mean is there still headroom to consider an upgrade or possible component aging or something? ---- if there is still room, up to what GPU can the 500w psu handle without pushing it to the limit? According to cooler master's psu calculator, my system will be using 284W http://coolermaster.outervision.com/PSUEngine2 But according to Palit's site, the minimum recommended system power is 300W http://www.palit.biz/palit/vgapro.php?id=2252 Specs CPU: Intel Core i5 4460 Motherboard: Asrock H97M RAM: Kingston HyperX Memory 8GB GPU: Palit GTX 750 Ti StormX Dual Storage: 1TB WD Blue, Crucal M500 240GB, old 80GB Seagate HDD Case: Coolermaster N300 Thanks!!

Hi, Should I take the Corsiar RM750 or the Cooler Master V750. Thanks

Hey! This is my firs buid and I don't know what power supply to chose. Please help me PCPartPicker I am thinking at a 750 power supply but I don't know which one should I chose. -EVGA Supernova G2 750W ($128) -Corsair RM750i ($150) These are the best prices at the moment in my country Please tell me if a 750 PSU it's ok for me and if so wich one should I chose. Thanks in advance!

Anyone know of a standard cheap 750w power supply

I'm builiding my first desktop in a couple weeks and have everything set except for the PSU. It needs to be gold-rated, full-modular, and come from a reputable brand (also keeping in the price range). Build- Intel i7-5820k- microcenter has one at $300 near me, same price as a 4790k but with 4 more threads- count me in MSI X99s PLUS Corsair H100i Crucial Ballistix DDR4 8GB EVGA GTX780 ACX Phanteks Enthoo Pro Intel 740 SSD (got an excellent newegg deal) WD Caviar Blue HDD Windows 8.1 Random DVD drive, whatever is cheapest when I order it. Intel N6205 wifi card My uses will be gaming, photo/some video editing, and CAD (nothing too heavy, but still stuff like Inventor and Alias), but mostly gaming/CAD. I'm currently looking at http://www.amazon.com/Corsair-Series-80PLUS-Gold-Certified-Supply/dp/B00EB7UITQ/ref=sr_1_1?ie=UTF8&qid=1410210522&sr=8-1&keywords=corsair+rm750 and http://www.amazon.com/EVGA-SuperNOVA-80PLUS-Certified-220-G2-0750-XR/dp/B00IKDETOW/ref=sr_1_1?ie=UTF8&qid=1410210994&sr=8-1&keywords=evga+supernova+750 Any thoughts? Thanks in advance- and stay tuned for a build log soon!

I have been holding off on preordering Watch Dogs because I'm not sure if the 2GB GT 750M in my current laptop will be enough to run the game at a playable FPS at decent settings. I know CPU and RAM won't be a problem I have 8GB of 1600mhz ram and an i7 3630QM @ 3.4GHz.
