AMD is not the first company to have a massive L3 cache: Intel did that seven years ago with Broadwell which featured a massive 128MB L4 cache and showed crazy improvements in certain applications and games as well.
L4, not L3. ofc massive Cache is not a new thing for CPUs, but now we are at a point where especially the latency is extremely good with AMDs L3.
800X3D is a single experimental CPU which rocks in some games but loses in others and also loses in general applications which don't require enormous L3 cache due to decreased frequencies.
It's not an experimental CPU, just look at what the massive L3 is capable of at Milan-X. That's the future because you get "free" performance boosts without launching a whole new architecture.
Very few people game at 720p or 1080p with their uber GPUs, and at 1440p and 4K most games are GPU bound and don't care about your L3 cache.
Doesn't matter how many ppl are gaming at 720p. That's not the point of CPU benchmarks. You want to know how much fps a CPU can deliver and for that you need lower res to eliminate the GPU as a limiting factor. Allthough I don't think that's the case in the benchmarks here since for a lot of the games the CPUs are all too close to each other. Smells like GPU bound in 720p which is... not a good way to test a CPU.
And for benchmarks you should never use the integrated ones since they suck (but what I think happened here a few times) and if you're ingame the FPS are always worse since the games themselves are way more demanding.
Thing with lower res is: If your 3090 is capable of delivering 80fps in 2160p and the bar shows 80fps, you don't know how good the CPUs are. If the bar shows 115fps and you know the 3090 can only deliver 80fps, you know how good the CPUs are and were the GPU is the bottleneck. What is especially important for future GPUs and if the rumors are true we are getting like >2x performance with the next GPU gens coming this year already.
Besides that I don't like testing games with 3xxfps or even more in CPU benchmarks. Who cares about 340fps or 370fps? There are heavy CPU bound games out there like Anno, Total War, Cities, hell even in Elden Ring you're looking at something way below under 100fps for the CPU. Why not test those games where you actually need a lot more fps?
RPL according to the leaked information will feature an increased IPC for both its P and E cores as well as a
significantly increased caches which means Intel will swiftly catch up and overtake this CPU and maybe even Zen 4.
According to the leaked information the IPC increase won't be large and the increased cache is "only" L2. Will help a bit here and there but nothing special.
This is the last hooray of AM4, there's no future upgrade path.
And yet for ppl with old AM4 boards and Zen2 or earlier they get a big last upgrade if they're mainly into gaming. Looks exciting enough to me comparing the original Zen (1800X etc.) with the 5800X3D and looking at the huge performance difference. Requiring no new socket or mainboard.
