RapydMark for Windows (frikiscape.com)

Synthetic highly parallel benchmark.




My company's dual socket Ivy Bridge-E beat Comet Lake in total time, only due to more cores. Should be fun to see how 5950X and i9-12900K fare in this benchmark. My guess is that 5950X will win.

Update: 5950X did win! But i9-12900K put up a good fight despite fewer cores.

Performance comparison chart so far thanks to Makaveli:

CCD comparison by Det0x:

1 CCD -> 8 cores / 8 threads = 368.309 seconds
1 CCD -> 8 cores / 16 threads = 230.797 seconds
2 CCD's -> 16 cores / 32 threads = 135.978 seconds

Interesting HT/no-HT comparison:

Need to edit the result of my overclocked OC to 5400. I had something running on the backround that might have affected the result. Fresh from boot, here is the result of my memory OC'd to 5400

View attachment 53585
I think this test likes fresh boot my score went up too (time lower 254.442)

comparing the memory test from your DDR5 to my DDR4 we can see big changes in the first few memory tests.

File memory - DDR5 =25.805, DDR4 = 38.418
Copy memory- DDR5 =16.752, DDR4 =22.326
memory cache performance - DDR5 =12.600, DDR4 =14.061
Memory Encrypt/Decrypt AES256- DDR5 =9.148, DDR4 =9.687
Memory Encrypt/Decrypt Blowfish448- DDR5 =6.186, DDR4 =6.249
Memory Compress/Decompress 1 MB - DDR5 =7.726, DDR4 =7.703

pbo2 = yes
overclocked = "no"
speed = 4.4 - 4.8 Ghz ( it spends most of the tests at 4.4 )
dram = 1780 x 2 Mhz = 3600 16 18 18 38 58 1T

Matrix Multiplication is 2.4s vs 9.4s

I find it hard to believe ADL is 4x worse at matrix multiplication,

The impact of cache locality on performance in C through matrix multiplication | by Gunavaran Brihadiswaran | Level Up Coding (gitconnected.com)

Very eye-opening article that shows matrix multiplication performance depends on cache locality.

Also, this may contain a clue: Zen 3: Load/Store and a Massive L3 Cache - AMD Zen 3 Ryzen Deep Dive Review: 5950X, 5900X, 5800X and 5600X Tested (anandtech.com)

The L3 continues to maintain shadow tags of the cores’ L2 contents – so if a cache line is requested by one core and resides on another core in the new core complex, the L3 will know from which core to fetch that line back from.
Something about Ryzen's cache architecture is helping it avoid cache misses when doing matrix multiplication.

Would 3D Cache further improve this?

Intel has 30MB of L3 + 1.5MB of L2, AMD 8C has 32MB of L3 and 512KB of L2.

Times without HT 8C vs 8C, at equal clocks of almost 5ghz for both CPUs:
14.3s vs 2.4s

Makes very little sense for such small difference in cache size to result in difference that large when no other test is showing anything at all. At some point one starts to question the validity of benchmark.
Maybe it is exacly 32MB of size and fits ZEN3 caches? Maybe access pattern defeats Intel's prefetcher in some strange way? Maybe AMD's branch prediction is always right.

Hard to tell without source code or Intel's VTune that is working on Alder Lake.

What is interesting, going from CL14 to CL13 has shaven 1s from runtime in that test, that is kinda shouting about ton of L3 cache misses.

No worries about this test tho, Intel has equally nonsensical win in Memory cache performance, so they cancel each other out

Latency may play a bigger role than size there. Would also explain the improvement from going from CL14 to CL13.

it's the same speed
Patrick Kennedy from ServeTheHome says that the V$ die has a slightly higher latency than the base die, but it's miniscule compared to the latency going to DRAM, so it effectively can be ignored:
The Microsoft team also told us that some of the gains here are enormous. I asked specifically about the additional latency for the stacked cache segments. The response I got was very simple. The base case cache is basically the same. There is a very small latency to go to the stacked cache. On the other hand, that small latency to go through the interconnect up to the stacked die is so much smaller than going off the CCD, through the IO hub, then out to memory and back, that it is effectively irrelevant from a performance penalty perspective.

Interestingly, Microsoft state the following:
It is also important to note that because of the unique packaging AMD has utilized to achieve much larger L3 caches (i.e. vertical die stacking) that the L3 latency distribution will be wider than it was with Milan processors. This does not mean L3 memory latency is worse, per se. Best case L3 latencies should be the same as compared to Milan’s traditional planar approach to L3 packaging. However, worst case L3 latencies will be modestly slower.
