OcUK RX7900 series review thread

[Koogle]

Known Issues​

• Corruption may be encountered when using Virtual Super Resolution with multi-display configurations [Resolution targeted for 22.12.2].
• A system crash may be observed when changing display modes with 4 display configurations [Resolution targeted for 22.12.2].
• High idle power has situationally been observed when using select high resolution and high refresh rate displays.
• Intermittent app crashes or driver timeout may occur when using Radeon Super Resolution with some extended display configurations.
• Video stuttering or performance drop may be observed during gameplay plus video playback with some extended display configurations.
• Stuttering may be observed in UNCHARTED™ 4: A Thief’s End during the opening game sequence.
• While loading Marvel’s Spider-Man: Miles Morales™ an app crash or driver timeout may occur after enabling ray tracing settings [Resolution targeted for 22.12.2].

So it's acknowledged in the latest driver release..

• High idle power has situationally been observed when using select high resolution and high refresh rate displays."

just nothing on when it will be fixed.. tbh I'm astonished such a thing slipped, reading other boards seems AMD have had this problem for a while.... something they need to sort out, otherwise it just makes the nvidia cards look better on overall idle power consumption.

4080 16gb is without a doubt a 4070 card and it has the AD103 gpu and a 256bit bus. Its not a 80 series card.

What does that make the 7900.

Interesting that TPU's review of the ASUS OC and XFX Merc models has them both OCing over 3GHz and essentially bridging the gap between the 4080 and 4090 at least in Cyberpunk 2077. https://www.techpowerup.com/review/asus-radeon-rx-7900-xtx-tuf-oc/39.html

Seems like 3Ghz+ is real after all, as long as you pump it with some power.

That actually is interesting, if AIBs can squeeze much better performance out then they may justify their inevitable price hikes…. To some extent anyway!

overpriced 7800 (7900xt) and 7800XT (7900XTX) AT BEST.

For a 7 fps gain in cyberpunk, sounds amazing.

For a 7 fps gain in cyberpunk, sounds amazing.

Could mean some good results with undervolting possible.

I wonder how bad the rumoured 7800XT with 60CU's will stack up against the 72CU 6800XT given the 84CU 7900XT only beats the 80CU 6900XT by 20%.

That is true.

They probably price that at £749 if the 7900 does not fall in price.

 

[harmattan]

What does that make the 7900.

The near full-fat to chip for £1000 and a slightly cut-down top chip for £899. But performance wise, 7900 slots in almost exactly in the pricing model that nV set when considering RT performance.

That is impressive. A >11% real FPS gain in CP for the ASUS TUF 7900xtx when overclocked to 3.1Ghz, within spitting distance of 4090 (RT off, of course)

Edit: Worth mentioning, looking at the reviews where they overclocked, the reference card seems it tops out around 2.9Ghz, so still not too shabby. As usual, the AIBs go that extra distance ~4-5%

For a 7 fps gain in cyberpunk, sounds amazing.

10% gain is pretty decent for a gfx overclock these days, as long as these weren't golden samples and 3GHz+ is consistently reachable with more power and a decent cooler then it's a bonus over the 4080 for me.

 

[timorous]

3 pin AIB OCs well.

 

[Trypta]

3 pin AIB OCs well.

This seems promising if it's matching a 4090 in Cyberpunk of all games.

 

[sgoaty]

Looks like OCUK managed to sell all the 7900xtxs

 

[Marine-RX179]

Looks like OCUK managed to sell all the 7900xts

XTXs yes; XTs no.

The XTs really should had been another £100 cheaper considering the performance gap being quite a distance away from the XTX.

W1zzard has the Asus with overclocking as +23.1% faster than the reference card.
Power usage is bound to have gone crazy for that though, although TPU don't measure OC power consumption.

 

[Martini1991]

AMD and Nvidia are jointly making PC gaming unviable for people
At current trends we'll have to spent a fortune on a mid range GPU .

Fixed it, that's what I meant
