RX480 Benchmarks out!

[Hadwell]

yeah it's not really practical to SLI cards as bad as the GTX1060, and the reason it has an integrated cooler is the same reason cards like the Geforce2MX and TNT2 and stuff do.... they just don't get hot enough,even fully maxed out, to bother with custom coolers... there are cards you can game with, and gaming cards... the GTX1060 falls under the former category...

 

on that note, i wouldn't doubt that in the future more cards don't even require a fan, with how everyone is aiming for efficiancy over just raw power, less and less heat is being wasted, so less and less cooling is needed...

 

the top end cards will always be hot, because they're always pushing the limits, but lets say a top end card draws 150 watts of heat, and can get 200 fps in a game, so then a card half that speed would draw probly less than 75w heat and still get 100 fps in the game... so basically anything less than that 75w heater really won't need much cooling at all...

 

base a cards performance and cooling requirements on how much heat it produces vs how many fps it gets in your favorite game...

 

don't base the cards performance on how much heat the card produces, completely disregarding its performance....

 

with the RX480 out there, the GTX1070 being actually pretty inexpensive for what it is, and the GTX1060 being pretty low-end at somewhere around the same performance as the RX480... it's understandable...

 

with all this said... honestly AMD has a very limited amount of options to compete with nvidia, AMD may have a lot of innovations, do a million things better with their cards than nvidia does, but if they can't pump out the fps people want, with reasonable current draw and noise levels, in the games people actually play, then all those innovations won't save them...

 

the games people actually play being the big thing AMD seems to forget... with their lists of like 5 games that run on AMD cards better than nvidia...

I read today that some of the benchmark guys reportedly used a wrong driver, and there was already an improved one. Still the power issue, but the cards are a bit faster. Still not near the 1070 (yet?) though.

 

As an AMD fan (or better Nvidia hater), I can tell you that it will never come close to the 1070. It wasn't designed for that.

There are reports of consumers having PCIe power circuits blown out on cheaper mainboards, I doubt its a "used the wrong driver" issue, its more of a tdp limit was not set problem.

 

Id like to know how much they overclocked it to blow out the circuit completely, a spec PCIe slot can handle spikes fine, they must have ramped up the core voltage to get sustained 100w+ power draw for an enlongated period of time.

There is a youtube (or twitch) video where some guy traced out the entire power circuit, and it turns out half the VRMs power comes directly from the PCI-E connector.

 

the 6-pin could handle the entire VRM, be out of spec, and still be fine, but what the RX480 really needs is the entire VRM on a single 8-pin, and to just not use PCI-E for it at all

 

the problem isn't with software or firmware, it's that half the power phases are directly PCI-E powered...

 

hopefully some non-refrence cards don't do that.

it's only the 8GB Versions from what I can tell having this issue,

 

the 8GB Versions shoulda been 8 Pin.

[Hadwell]

this is a different video than the twitch one, but it shows what I mean about the pci-e slot powering half the VRM...

 

they say in this video that a firmware update might fix it, but if you watch the twitch video (it's actually linked in an earlier post in this thread) you'll see that you can't fix actual physical copper traces with software, so we'll see...

a 14nm GPU shouldnt need to draw 1200mv, that's an issue by itself.

[SkateZilla]

Apparently some of the 4GB Units can be flashed back to 8GB:

I dont usually like toms, but this was spot on:

As mentioned previously, if you bought a 4GB Card on Launch day, you may have gotten an 8GB Card that was Firmware Gimped to Sell as a 4GB to meet demand,

 

Meaning you can flash the puppy w/ the 8GB BIOS, unlock the other 4 GB of VRAM and increased clocks

Well, an interesting comment form a professional: An electronics engineer:

 

TL;DR: According to him, there's no problem with the card and it won't damage the PCIe connector.

And an 8 cyl version of that 4 cyl engine?

 

Transistors are not engine cylinders...

 

Comparing aardvarks to blaupunkts...

 

Post makes no sense whatsoever.

Powercolor Devil arrived today, totally transformed DCS in VR compared to my 7950. very pleased with it :D

[Hadwell]

Post makes no sense whatsoever.

 

That's the point, comparing how engines produce kinetic energy to how transistors work makes no sense.

 

In the same way comparing an aardvark to a car stereo makes no sense.

If you have intricate knowledge of how both work and how to squeeze power from both then it makes a lot of sense.:thumbup:

but he was saying he can have a 4 cylender engine produce the same power as an 8 cylender engine....

 

you can't make a GPU with half the amount of transistors produce the same amount of polygons per second as a Gpu with twice as many transistors in the same game...

 

the two things just aren't the same... and it makes no sense at all...

 

or maybe you can find any kind of CPU or GPU with half the transistor count that runs as fast as a CPU or GPU with twice as many transistors...

 

and sure you can add a super/turbocharger, a phsyical piece of gear to a engine to make it produce more power, you can change its timings, or edit its ECM

 

can you bolt on a piece of gear (other than a heatsink) to a GPU to make it run faster? and the closest thing to editing its ECM is something like MSI afterburner or EVGA percision X...

 

As an example, the GTX1080 has 7.2 billion transistors, and the GPU with half the amount of transistors is the GTX680(roughly) 3.5 billion.... show me how to make a 680 have the same performance as a 1080? how about half the performance?

Science has proved over time that what isn't possible now will be possible one day.
