AMD Ryzen 7 2700X and Ryzen 5 2600 Software VM Performance


AMD Ryzen 7 2700X and Ryzen 5 2600 Software VM Performance

We are testing arithmetic and vectorised performance of software virtual machines (SVM), i.e. Java and .Net. With operating systems – like Windows 10 – favouring SVM applications over “legacy” native, the performance of .Net CLR (and Java JVM) has become far more important.

Results Interpretation: Higher values (GOPS, MB/s, etc.) mean better performance.

Environment: Windows 10 x64, latest drivers. .Net 4.7.x (RyuJit), Java 1.9.x. Turbo / Boost was enabled on all configurations.

AMD Ryzen 7 2700X and Ryzen 5 2600 Benchmarks Leaked!

.Net Dhrystone Integer : .Net CLR integer performance starts off OK with Ryzen2 just 8% faster than Ryzen1 but now almost 3x (three times) faster than i7.

.Net Dhrystone Long : Ryzen seems to favour 64-bit integer workloads, with Ryzen2 20% faster a lot higher than expected.

.Net Whetstone float/FP32 : Floating-Point CLR performance was pretty spectacular with Ryzen already, but Ryzen2 is 15% than Ryzen1 still.

.Net Whetstone double/FP64 : FP64 performance is also great (CLR seems to promote FP32 to FP64 anyway) with Ryzen2 even faster by 20%.

Ryzen1’s performance in .Net was pretty incredible but Ryzen2 is even faster – even faster than expected by mere clock speed increase. There is only one game in town now for .Net applications.

.Net Integer Vectorised/Multi-Media : Just as we saw with Dhrystone, this integer workload sees a 9% improvement for Ryzen2 which makes it 2x faster than the i7.

.Net Long Vectorised/Multi-Media : With 64-bit integer workload we see a similar story – Ryzen2 is 8% faster and again 2x faster than the i7.

.Net Float/FP32 Vectorised/Multi-Media : Here we make use of RyuJit’s support for SIMD vectors thus running AVX/FMA code; Ryzen2 is 11% faster but still almost 2x faster than i7 despite its fast SIMD units.

.Net Double/FP64 Vectorised/Multi-Media : Switching to FP64 SIMD vector code – still running AVX/FMA – Ryzen2 is still 12% faster. i7 is truly left in the dust 1/4x the speed.

Ryzen2 is the usual 9-12% faster than Ryzen 1 here but it means that even RyuJit’s SIMD support cannot save Intel’s i7 – it would take 2x as many cores (not 50%) to beat Ryzen2.

Java Dhrystone Integer : We start JVM integer performance with the usual 12% gain over Ryzen1.

Java Dhrystone Long : Nothing much changes with 64-bit integer workload, we have Ryzen2 12% faster.

Java Whetstone float/FP32 : With a floating-point workload Ryzen2 performance improvement is 13%.

Java Whetstone double/FP64 : With FP64 workload Ryzen2 is just 7% faster but still welcome

Java performance improves by the expected amount 7-13% on Ryzen2 and allows it to completely dominate the i7.

Java Integer Vectorised/Multi-Media : Oracle’s JVM does not yet support native vector to SIMD translation like .Net’s CLR but here Ryzen2 manages a 15% lead over Ryzen1.

Java Long Vectorised/Multi-Media : With 64-bit vectorised workload Ryzen2 (similar to .Net) increases its lead by 24%.

Java Float/FP32 Vectorised/Multi-Media : Switching to floating-point we return to the usual 14% speed improvement.

Java Double/FP64 Vectorised/Multi-Media : With FP64 workload Ryzen2’s lead somewhat unexplicably drops to 1%.

Java’s lack of vectorised primitives to allow the JVM to use SIMD instruction sets (aka SSE2, AVX/FMA) gives Ryzen2 free reign to dominate all the tests, be they integer or floating-point. It is pretty incredible that neither Intel CPU can come close to its performance.

Software VM Performance Summary

Ryzen1 dominated the .Net and Java benchmarks – but now Ryzen2 extends that dominance out-of-reach. It would take a very much improved run-time or Intel CPU to get anywhere close. For .Net and Java code, Ryzen is the CPU to get!
