News Intel Arc A770 GPU Memory Clock Bug Fixed With Driver Update

[Admin]

Intel's new Arc A770 has reportedly succumbed to a memory clock bug, resulting in a 17% loss of bandwidth earlier this week. Thankfully the issue has been fixed thanks to a new beta driver.

This is good.
We knew there were bugs. Nice how this one was promptly fixed.
There are a lot left, mostly seem like driver resource scheduling where one game inexplicably runs worse than another. For example AC Origins runs terribly at all resolutions, (mixed settings I used when I had a 1080ti) (dropping to ~15fps depending on the scene) with my A750 and AC Odyssey runs fine at 1440p, same settings (steady 60+). They are practically different stories/locations in the same game. I never finished Origins due to the story so I don't mind this falling behind in optimization priority, but it shows driver improvement potential in underperforming games.

I think the fine wine will be strong with the Arc series as long as Intel's driver team keeps working at it.

Can anyone actually find these cards? I actually tried checking them out for the video encoding acceleration

Unless two bugs were fixed, the 9% drop in clock speed from 2187 to 2000 MHz yields a 9% drop in bandwidth as well.

I picked up my A380 from Newegg a few days after release and purchase was like they had normal quantities. They are in stock right now. When the larger ones came out I was at work and some reason couldn't finish the purchase on my phone even though it was in my cart. Kept checking Newegg every couple days and the A750 reference was in stock one morning so I nabbed one of those. Not nearly as bad as the crypto days of the 3000 and 6000 series, but availability is bad.

The obvious question is whether this affected any benchmarks published by independent reviewers.

I have a theory that Intel is holding back the A780 for a time when they've fixed up a lot of their driver issues. By releasing a new model, they'll effectively force all benchmarks to be rerun, even if the hardware is merely a 16 GB A770 with a slight bump in clock speeds.
