Anyone is using 64 cores besides Linus :) I'm much more excited for 7900x on 12 cores rather than 64 cores. But I understand the limited amount of people that needs this power on desktop can also be excited.
I could use an almost indefinite number of cores for fuzzing and compiling. Currently I have to limit my fuzzing runs to 12 cores because the 3 year old AMD machine can't handle more without impacting other development work.
But then if 64 is not useful to you, why the 7900X instead of the 7700X and it's 8 cores? The 7700X is way less power hungry and boosts to nearly the same speed as the 7900X.
Genuinely asking as I plan to replace my Ryzen 3700X with a 7700X.
im on 3900x and i was planning to upgrade to 7900x i tend to run few VMs. But I'm not sure yet. Would be cool to get on DDR5 but it feels like this time it is just to have upgrade. So not sure.
Some common dev work loads that benefit: huge builds (especially for C++ and Rust), running lots of VMs to run a copy of a cloud infrastructure locally, emulating foreign hardware for testing (qemu), large scale data analytics locally instead of paying some ridiculously expensive SaaS to do it.
I'm actually considering upgrading to 5800x or 5800x3d as a cheap temporary upgrade since the newest generation (which I initially planned on) just seems too expensive given the need for new DDR5, and new very expensive motherboards which will likely need at least another year to mature. So far I've been leaning towards the pretty cheap 5800x (280e vs 450e for 5800x3d) since the difference actually doesn't look that big for real workloads (and since it's an upgrade for a shorter than usual timeframe). Is the 5800x3d actually 60% better in non-gaming to be worth it? If not (as it seems to me) I'm not sure why waiting for the next 3d specifically makes sense.
X3D seems to shine in gaming but likely helps with other code that is not computation-heavy as well. If you don't need AVX-512 or higher memory bandwidth, either 5800 CPU is probably good. X3D is going to be a bit more future-proof, requiring a later upgrade, based on how well 5775C holds up even today.
