PCI Express 4.0 Brings 16 GT/s And At Least 300 Watts At The Slot

[DXMember]

300W ????

wtf... did they just mass produce superconductors?

And? PEAK power consumption is 294w on just the card. They also were very clear that peak is NOT the same as average...and what, is Anandtech not a reliable source? Anandtech puts the total system draw at 410w, which falls in line with Guru3D's estimation. So again, the power draw and the electric bills aren't what you're making them out to be. 

 

At peak, a 6700k only draws 130w~ while a 5960x draws 180w~. ( http://techreport.com/review/28751/intel-core-i7-6700k-skylake-processor-reviewed/5 )

 

And Anadtech's estimates are using Haswell-E, not Skylake or regular Haswell. 

My 4790K draws 120W under Prime 95 (stock), around 88W under any other full load, and 117W at 4.8GHz 1.3V under any other full load....TDP is BS.

Good news for RX 480 owners.

I'm not going by TDP. I looked up Anandtech's (peak) power consumption benchmark.

People question the 300W power delivery when everyone is smiling and nodding at USB 3.1's up to 100W power delivery on tiny pins?

 

300W on 12V is 25A total. If we went by this chart, you can easily get away with delivering that much power on two 16 AWG wires. 16 AWG isn't really that big. Though I'm sure better EE's in here can talk about this.

I'm just pointing out that stated TDP are BS (as you can see on Anandtech).

[Mira Yurizaki]

Are people still thinking TDP is power consumption? Because it isn't. I mean, the word Thermal should tip you off.

[Doobeedoo]

Nice seeing it moving forward, something that won't become bottleneck easily. Though those kind of watts at the slot. Interesting. And what about lanes though.

Also, wasn't there a mention before that next gen PCIe could potentially be optic-based of some sort cause copper won't be able to keep up? Though still it manages so far.

But..i was talking about GPU.. 
m2 has reach 32Gb/s .. and how can u saturate all that bandwidth with m2 ssd?

You use 3D XPoint. Micron already showed their QuantX SSDs can saturate pcie 3.0 x8 in random read and write, not sequential, and pcie 4.0 x4 offers the same bandwidth as pcie 3.0 x8, so while pcie will still be the bottleneck it would offer a pretty big performance jump for 3D XPoint. Double the performance in synthetics for sure, though I don't know what it would mean in real world scenarios.

That's because TDP is different from power draw. TDP is Thermal Design Power which refers to the amount of heat something will emit, which is close to but different from power draw.

Cool. I've been waiting for a 300 watt TDP gddr6 Titan XP 2 with no PCI-E cables.

Until CPU interconnects become optical, I don't see a point in putting it on an internal bus.

 

Besides, video cards don't need PCIe 3.0 x16. You can still drop a GTX 1080 to PCIe 1.1 x8 before you get serious degradation

That was fixed a while ago.

does AMD even have a board with PCIe Gen 3 get?

lol, optical transistors.

FM2+ and one or two AM3+ boards.

Correct, it was. 

 

It was also a joke.

It's not even that dirty. People seem to think reducing 90% of the emissions from coal and oil plants is insignificant. Heck, the biggest contributing factor in greenhouse gasses is water vapor.

...how are you suppose to handle flippin 300W to the pci-e connector?

I guess the only way is to connect PEG plugs to the motherboard which doesn't make sense because you can plug them into the GPU if you need it anyway...

If they do that it will still be better imo, it will enable even cleaner builds.

Yeah, they're loaded because they can afford an extra $50/year electricity bill. 

 

Let's assume the system is used at full load for 4 hours a day 365 days a year (which is pretty fair/generous assumption). Now the average electricity cost is $0.13/kw/h. So, 365days/yr * 4hrs/day = 1460 hours. A Fury X based system pulls about 400w at full load ( http://www.anandtech.com/bench/GPU16/1533 ). So a system with two Fury X's should be around 650w~. Now assume the PSU has a 90% efficiency, and your power consumption under load is about 720w. So math time: 

720w * 1460 hrs * $0.13kw/hrs / 1000 = $136/year.

 

Now if we were to use a two 980Ti, then it would be 40w~ less, which would be $129/year. 

 

Or if you were to use a single GTX 1060, then it would be 300w~, which would be $57/year. 

 

So yeah, enthusiasts must be loaded because they can afford to spend an extra 10 hours worth of minimum wage a YEAR. Also, anyone who would buy AMD anything must be a moron...I mean, $7/year is really bank breaking stuff. 

those 7$ are the worst. I mean, its not like their GPUs are generally 25-50$ cheaper for a good model in the first place. So those 7$ really break the price to performance ratio.

Having nuclear plants helps a bit

Water vapour comes to play later, since water has a different cycle than other greenhouse gases and it's influenced a lot by temperature. Moreover it can have the opposite effect, since more water vapour leads to a higher cloud formation and that rises the Earth's albedo. The main "actual" contributor is CO2, followed by methane and nitrous oxide, since they don't have anything like the water cycle. CO2 is also very dangerous for seas and oceans because it tends to dissolve inside water and this lowers the overall pH, causing issues to underwater fauna and flora (which accounts for most of the Earth's oxygen production)

300 watts via pcie? meaning no more 6 pins or even 4 pins required, Sounds good

Well that depends where they put the connector.

If they put it right above the PCI-E connectors it's not exactly helping...

 

The old Ramage III Extreme for example had 2 molex connectors above the pci-e slots, that's not exactly a spot that helps a cleaner build.

a 90% reduction? over what? the last 50 years? Our energy is still dirty AF but global warming is just a myth so why bother?
