AIDA64 CPU Benchmarks
Now we will look at some specific AIDA64 CPU Benchmarks which test specific parts of the CPUs. The AIDA64 PhotoWorxx benchmark stresses integer arithmetic and multiplication execution units of the CPU and also the memory subsystem. The AIDA64 AES benchmark performance using AES data encryption. The SHA3 benchmark tests CPU performance using the SHA3 hashing algorithm and is AVX-512 aware. The FPU Julia benchmarks measure the single-precision floating-point performance of the CPU. The FPU Mandel CPU test tests the double-precision floating-point performance of the CPU.
CPU PhotoWorxx
In AIDA64 CPU PhotoWorxx benchmark the new AMD Ryzen 9 7950X is a whopping 97% faster than the previous generation Ryzen 9 5950X CPU it is replacing. Compared to the Ryzen 9 7900X the 7950X is 0.4% faster, so both are very similar. Compared to the Intel Core i9-13900K the Ryzen 9 7950X is 28% slower.
CPU AES
In AIDA64 CPU AES benchmark the AMD Ryzen 9 7950X is a very big 45% faster than the Ryzen 9 5950X previous CPU. Compared to the Ryzen 9 7900X the Ryzen 9 7950X is 31% faster, showing that the added cores really help here. The AMD Ryzen 9 7950X is also 28% faster than the Intel Core i9-13900K.
CPU SHA3
In AIDA64 CPU SHA3 benchmark the Ryzen 9 7950X is 66% faster than the previous gen Ryzen 9 5950X. Compared to the Ryzen 9 7900X the Ryzen 9 7950X is 30% faster. The Ryzen 9 7950X is 13% faster than the Intel Core i9-13900K.
FPU Julia
In AIDA64 CPU FPU Julia the AMD Ryzen 9 7950X is 36% faster than the Ryzen 9 5950X. Compared to the Ryzen 9 7900X the Ryzen 9 7950X is 23% faster. The Ryzen 9 7950X is 36% faster than the Intel Core i9-13900K.
FPU Mandel
In AIDA64 FPU Mandel the AMD Ryzen 9 7950X is 26% faster than the Ryzen 9 5950X. Compared to the Ryzen 9 7900X the Ryzen 9 7950X is 18% faster. The Ryzen 9 7950X is 34% faster than the Intel Core i9-13900K.
Memory Read
The DDR5 memory read performance of the AMD Ryzen 9 7950X is around 74.9GB/s of bandwidth. This is 39% more memory bandwidth than the previous generation Ryzen 9 5950X with DDR4. The Intel Core i9-13900K, with the same memory modules, does have more bandwidth by 27%.
Memory Write
The memory write performance of the Ryzen 9 7950X is 76.8GB/s which is 45% more than the Ryzen 9 5950X. The Intel Core i9-13900K has 9% higher memory write bandwidth than the Ryzen 9 7950X.
Memory Latency
The AMD Ryzen 9 7950X is slightly on the higher side of memory latency at 68.8ns. The Ryzen 9 5950X with DDR4 has 10% better latency. The Intel Core i9-13900K, however, is very close to on par with the latency of the Ryzen 9 7950X.

Thanks, @Brent_Justice for the great review! I'm keeping a keen eye on all these new processors as I gather knowledge for my next build. I can't wait to see what the 3D Cache 7000 series does.
Nice review... yea I'm definitely skipping this generation of CPU's my 5900x is plenty fast for what I do at 1440p.
Great review! Now how do I cool the stupid thing? And is my "old" 800w power supply going to keep up?
Microcenter has the 7950x + 32gb ddr5 6000 gskill ram for $567, and the 7900x same ram bundle at $469. Looking at those gaming charts, 4k is totally GPU bound, but 1440p seems to be the sweet spot. I think I would swing for the 7900x personally.
I also play (more than I should) a fair amount of Civ 5 + Vox populi.... it is my understanding it is a mostly single threaded game. I have cranked my 5700x to the max while playing, trying to cut down on the time between turns when AI is working.... doesn't seem to make much difference. I see one or 2 cores pegged out and the rest do nothing. So I'm not even sure the $567 upgrade (and $250+ for a new mobo) would make a difference. I generally prefer AMD to Intel these days, but it seems like Intel does better on the single threaded stuff?
