    C2HWarrior reacted to hishnash in Tim Sweeney explains his comments with respect to IO pef on PS5   
    so its not about the raw decompression performance its more about the latency, they might well be using the same decompression functions of the Zen2 hardware but (through OS magic) not doing this in user-space so you don't have the massive lag when you need to jump from kernel to user to kernel to user space all the time.
     
    This is a big advantage for the GPU, in a normal desktop system were the VRAM and CPU RAM are separate the GPU needs to do one MORE (SLOW) copy of data to the GPUs VRAM before it can use it. by having a unified system as soon as the data has been copied from the ssd to the system memory it is already in the gpus memory since the system memory is also the gpu memory.

    The reason you dont do this on a Desktop is it means your gpu and cpu need to be hardwired to the same memory (making swapping a gpu) very very very hard.

    Yes it will impact cpu latency but for the PS5 all cpu operations in the end need to talk to the GPU so by sharing the same memory this communication is in the end a lot faster.
     
    No what he is saying is hey is bypassing the CPU as much as possible the idea is to get data from the SSD to the de-compression system and into VRAM (that happens to also be system ram so one less copy) without needing to jump through the large latency hits you get with using user-space apis as you would on a PC.  The advantage here comes if you are doing lots and lots and lots of very small reads
     
    for AMD the PS5 has been in the works since before first gen Zen cpus started being tested. They will have been doing a massive amount of optimisation, both Sony and MS have basically funded the development of Zen and stoped AMD from going under.
     
    Game engine devs and driver devs need to consider this. Normal day to day devs dont.  All the game engine providers get large amounts of money and help from Sony and AMD to do these sort of optimisations.
     
     
    One of the things that i think people are not getting is what having supper low latancy access to compressed data does. In a normal system you need to pre-load anything that might need to be used by the gpu at least a few seconds before it is needed just in case there is hiccup and its not there when you need it (if it is not there the default behvoir of a gpu is to *stop rendring frames* untill it arives,, that is how you get massive framerate drops)

    however if you have a stable (predicatble) low latancy means of getting this data you can get this data just before it is needed.
     
    So if you have a large high resh mesh that the user can walk around, normaly in a game engine when the user gets close enough you load the full high res mesn (and textures) into the gpu, and 1/2 of that data is wasted as it is data for the other side of the mesh, but the user could at any time move and see that side fo the mesh so you need to have it in VRAM. That means you need a very large VRAM since you end up loading a LOT of data that is of screen into VRAM.

    With nanite the aim is to only load data that is needed in frame into the GPU and this means in those demos as you move the camara it needs to pull data supper fast. Withoutthis you would need a muhc much larger amount of VRAM.!

    C2HWarrior reacted to fanatiXalpha in Workaround boosts Ryzen Performance for Intel MKL   
    @SpaceGhostC2C
    I get your point, this gets somewhat in the direction of "lawful evil" from Linus.
    Intel is probably in the right to do this, but it is an asshole move.
    Because, if you say "hey, we developed it and don't want that our competitor is good at it." Then why let the other CPU run the SW anyway?!
    Why not do it like so:
    "Our SW and so it does run only with our CPUs. With AMD, the SW won't start at all."
     
    But this, this is a real bitch move.
    Let it work, but in a bad way / with bad performance.
    Because the average user that uses Matlab or other SW that relies on MKL will have no possibility to see why it is that much slower on AMD than Intel.
    There is no indication which instructions are used to my knowledge.
    And so most of the affected users think:"Hm, AMD sucks really at making CPUs".
    But in fact, the don't.
     
    It would be like car manufacturer A develops a new formula for gasoline (for more power, efficiency or whatever) and sells it to every gas station so that everyone can buy it.
    But when a car from manufacturer B wants to get the same gasoline, the gas station detects that the car is from B and not A and proceeds by giving the customer with car B the standard gasoline without telling him*.
     
    And this is the point I have a problem with.
    Is it the right of Intel to do so? Probably, I'm no legal expert and from my moral standpoint I would say this shouldn't be, but I don't know.
    But in the end, still a bitch move.
     
    *With the same price, the same product name whatever.
    It is hard to make comparisons, because they are fundamently different things.

    C2HWarrior reacted to dizmo in Cyberpunk 2077 - multiplayer mode will have micropayments   
    I've said it before, and I'll say it over and over again.
    I don't care if a game has micro transactions that are cosmetic. Go ham, fam. If you're one of those people that need to have everything in a game, and that bothers you, I think you might need to seek counseling, as that sounds like a bit of a problem. To be perfectly honest, I wouldn't even care if you could buy in game items instead of grinding for them, as long as grinding was still an option and wasn't insanely out of proportion.

    Reading the arstechnica article:
    https://arstechnica.com/gadgets/2019/04/samsung-embraces-vertical-videos-with-a-16000-vertical-tv/
     
    The price is $1600 not $16k. It was only announced in South Korea so errors in translation (who really trusts Google translate?) are apparently to blame for the uncertainty. Either way Samsung aren't stupid. Nobody would pay 16k just for a rotating TV.

    Being unveiled and being released are completely different. Nobody expected Navi to be released until 2nd half 2019. Amd could have showed a teaser for Navi if they wanted to, we know it's near completion. It's seems however that they have a high number of defective mi60 cards that they need to sell so they released Radeon VII. They are not gonna be like "hey buy these cards now but in 7-9months time we are releasing a new, much better architecture". That's just bad business.

    C2HWarrior reacted to dwang040 in Decent In Ears around £100   
    I don't know what the conversion from pounds to usd is, however, the iem that I am currently using is the RHA ma750 for around $120 usd. While i'm no super-audiophile, and these are the only "good" iems I've owned so this is just my basic impression. 
     
    In short, I personally grew with these and I do enjoy the sound from it. At first, when I got them, they sounded "odd (probably been using skullcandies for too long)," too sharp in the highs, but over time, I swapped over to the dual flange for a better fit, burned it in from all my listening (probably the placebo effect/ me getting used to the sound signature finally kicked in) and that sharpness went away over time, and I grew used to its sound signature. In short, I have no complaints with how it sounds, but as I've mentioned above, I don't have an extensive collection of iems to compare them with, but I'm sure a lookup of se215 vs ma750 will give you some results. 
     
    Some pros: Sound (subjective, but I like it), build quality (I'm listening to music constantly, when I walk to class, go out to buy stuff, at my house, at my house, gaming etc. Really durable for my usage), a lot of accessories and tips for you to try out, really great support (The first pair broke after 2 years, they sent me another one free of charge and these are still fine 3 years later. I also asked if they sold extra dual flanges cause I accidentally ripped mine and if they also had those earwax filter things, and they ended up sending me some for free), 3 year warranty, fits well for me and provides great isolation.
     
    Some cons: Unlike the se215 no detachable cable, sound (again, it's subjective so you might not like them), the 750i breaks easily (the i is for integrated mic/controls. People have reported that the wiring there breaks easily, but I have the non i variant so I wouldn't know), fit and weight, finding the right flange tips was hard and in the end, the dual flange tips included worked for me. People have also said that they are a bit heavy since it's aluminum build. But being over the ear, I can't say I have that issue of them falling out easily and being too heavy. Less bass than the se215. I've read that people say there is more bass on the se215, I don't know cause I've never owned the se215. 
     
    Other suggestions: These are some iem's that were recommended to me as well when I was searching for an upgrade. The se215 (you already had them), Rock it sounds r-50, Zero Audio Duoza, Vsonic Gr07...

    C2HWarrior reacted to Carclis in Intel 9th Gen Paid Benchmarks Take Advantage of NDA Periods   
    Intel has recently revealed it's latest 9th generation line of products and subsequently opened up pre-orders for them. As seems to be typical in the tech space there were no benchmarks available with all of the tech journalists being held back by NDA periods. There was one exception however; a publication known as PCGamesN who published benchmarks conducted by Principled Technologies under commission by Intel. The results in question proposed that the new 9900k CPU was up to 50% faster than the Ryzen 7 2700X in gaming. Steven Walton of TechSpot has expressed his concerns over this and also pointed out numerous issues with the testing done in the report.
    After doing his own research he found that numerous and seemingly intentional steps were taken in order to handicap the Ryzen system and present the new Intel product in the best possible light. The comparisons were clearly not apples to apples and the problems only just begin with their method of applying XMP.
    Steve's testing found the results contradictory to his own testing when which he repeated for the sole purpose of trying to replicate the Principled Technology results. His results for the Intel systems were not far off sans 9th series parts which are still pending the NDA lift but the Ryzen system was quite far off as you can see below.


    For me this news is quite concerning. I'm not a fan of pre-orders, especially when no benchmarks are available. But to have commissioned benchmarks published during an NDA is a step too far and extremely deceptive.

    Steve Walton Follow-up
    AdoredTV Weighs In
    Principled Technologies are the Publishers of BenchmarkXPRT; a series of benchmarks that are largely developed and funded by Intel and is also used to make performance claims by Intel.

    The disclaimer is there as a requirement for Intel as a result of their previous meddling with BAPco which got them fined in excess of $1b by the FTC. The other requirement was that the FTC ordered that Intel claim it's stake in the benchmarking suite and outlet doing the testing whenever it makes a performance claim.

    At this point it doesn't look very good for Intel. They've been caught commissioning a "third party" whom Intel has funded and had publish Intel's own BenchmarkXPRT series of tests to release benchmarks during an NDA period where they cannot be refuted, also under the guise of a third party.

    MacOs and gaming do not get along. On top of that you've no dedicated GPU to speak of in the 13' MacBook Pro. Imo the matebook X pro is better suited to your needs. The 2018 MacBook Pro costs over $2000 to get just one of the upgrades. The Matebook gives you a 512gb SSD, the same i7 and 16gb of ram AND an mx150 all for under $2000. The mx150 will really help out in gaming.
