Intel 1x B65 with xeStrata Flash-Next 4-bit - 60tok/s - What a game changer for single card users

Wait 5 sec.

Howdy All, more test results from my b65 rig! This time I'm focusing more on what one single B65 can do, specifically 1x B65 with XeStrata. I threw in my A6000 for comparison, and I have to say, surprising how well B65 stacks up if you have the system ram to offload. Now my A6000 with Strata is faster, but when I'm using flash-next in librechat, 60 Tok/s feels fast... and when I compare the price to my A6000... I really start to question my setup. I think people really need to give the intel lineup a 2nd look, a lot has changed in only 6 months and even with this recent price bump, it's still the best entry level stack I've found.

The final IQ3_S row uses a different quantization; older B65 rows carry the contention caveat above. Engines and host environments differ; this does not isolate GPU performance.
