Intel Refers to its 3D V-Cache Analog as "BFC"

“It's anyone's guess what "BFC" abbreviates; Intel probably has some clever marketing name for that acronym, such as "big fusion cache," and of course gamers would know what "F" word substitute to use here.

The idea behind bLLC is the same as AMD had for 3D V-Cache. AMD discovered that enlarging the L3 cache of the processor can significantly improve gaming performance of the processor as it places more of the fast-moving game data, such as textures within 1/6th the latency of DRAM. While AMD stacks a slab of L3 cache memory on top of its CCD, over the central region with the on-die L3 cache to achieve a contiguously addressable cache block; Intel may use a different approach, such as having a cache tile sitting beside the Compute tile, with the ringbus of the compute-complex being extended to it, or short-terminating in the absence of it.“

Click to expand...

that a very funny way to say this... and Intel discovered that having a faster clock everything else equal improved the performance now

It was not some secret, it was often the reason the top SKU intel cpu were faster at gaming than the cheaper one, not the added cores that game had an hard time to exploit but the extra L3 cache, which everyone always knew was quite good for things like video game.

There was a lot of technical work and TSMC breakthrought to make 3d cache work, not some idea that it could be good for games.

They should go back to see what they did with the i5-13600K/14600K, and add BFC for that. Best gaming CPU for 2K and 4K that I have (beats the 9850X3D, 9800X3D, 270K Plus, and i9-14900K).

BFC may need to do a lot of heavy lifting. Kopite7kimi is saying standard Nova Lake performs like Arrow Lake in gaming (implying possibly worse than Raptor Lake).
