Radeon R9 295X2 In CrossFire: 25 Billion Transistors Game At 4K

[GOKU4LIV]

ATI/AMD is the BEST with API MANTLE RULEZ is FERRARI of PC .

 

[randomoneh]

At the end of the day, "only" 4GB of VRAM is usable by games, right?

 

[damric]

A pair of 295s would have done way better in a case like the HAF XB, where you can configure it for maximum airflow. Tower design cases are a relic of the past when it comes to high performance.

 

[lothdk]

When you do these benchmarks in the future with 4k resolution, could you please include vram usage?

 

[falchard]

I don't think the CPU can keep up with that unless its using DirectX 11.2 or Mantle.

Made a couple of spelling/grammar fixes and swapped out a couple of charts in Grid 2 that were incorrectly reporting Frame Time Variance. Thanks for the sharp eyes, folks.

4 way anything=BOOM! 😛

Don't use GUIminer. Simply switching from GUIminer to SGminer my 7950 went from ~350khs to ~550 khs with same settings. It now cruises at ~700khs 24/7 with higher clocks.

I would have liked to see how 3 way r9 290x in crossfire and gtx 780 3 way sli perform against 2 r9 295x in crossfire.
As usual dual gpu scales best and then it's downhill scaling with every gpu extra afterwards.

Why don't you use a dual Xeon set up? You could pair two Xeon E5-2690 v2 and an Asus Z9PE-D8 WS to eliminate CPU bottlenecks.

 

[emdea22]

550 kh/s ?!?! Oh toms as much as you are pros with benchmarking you are bad at mining. Took me 1 week to get my 280x at 750 without overclocking but its doable. The settings are different from card to card, bios to bios, hell, even revision to revision. Its an art to squeeze more kh/s out of a card and it takes time and effort.

 

[wh3resmycar]

stuttering mother F. lol

 

[ya right]

3d on chip memory will up the ante next year! pretty soon the entire computer will be made with 3d arcitecture to eliminate existing bus limitations and bottlenecks.

Stackable chips for scalability, motherboards will be shrinking considerably.

I find these Metro results puzzling. Here's what the folks at Anand Tech got at 4k with just one 295x2

Serious Driver work needed here. The problem clearly isn't in the hardware but in the software's ability to utilize the hardware. The same problem was seen with multi-core CPUs

 

[cst1992]

Sixteen Gigabytes of GDDR5 memory, yeah right. In quad CrossFire it's only 4 GB usable.

 

[killbilly]

Wondering Why it only show Radeon R9 295x2 in crossfire and not nVidia GTX 690 SLI?

 

[Ahmadjon]

CrossfireX still has poorest optimization, in some games two R9 295X2 decrease FPS instead of increase that FPS....

 

[youssef 2010]

Sixteen Gigabytes of GDDR5 memory, yeah right. In quad CrossFire it's only 4 GB usable.

That's a truth universally acknowledged in dual-gpu cards and multi-card configurations and is mentioned in the article when they were talking about the GTX 690.

 

[cst1992]

They'll probably show the 16GB as a gimmick for noobs.

 

[shogunofharlom]

The performance sux ... but MAN ... does it look cool! We have been waiting for gpu and game makers to fix cfx/sli support for years. Dont hold your breath on them working this out. However ... crazier things have happened. tom ... just do they multi-monitor review anyway. We will read it.

 

[Adroid]

Sick article.... Shows where technology is... And where it isn't.

I think I'll be waiting a few years (maybe 10) before I attempt any of this high res and/or multi monitor setups. 27" and 1200p is in my future possibly, where single cards can still manage ultra.

Spending 2000-3000$ for more monitors and GPUs and only getting 40-50 FPS is not super appealing, just my 2cents.

A completely different impression:
http://www.digitalstormonline.com/unlocked/4-way-quad-crossfire-amd-r9-295x2-benchmarks-at-4k-idnum228/

Is it possible to add at least one synthetic benchmark? It seems that in a few games not all the GPUs are working.
