Application Performance

PCMark x has been included only to cheque full general performance. There are no oddities hither every bit the 2990WX is comparable to the Core i9-7960X which is perfectly acceptable for a super core heavy CPU. The 2950X does exercise much improve though information technology comes in merely backside the 1920X.

Excel is a real-world application we've been using to criterion CPUs for year and years at present, and then why not effort the Monte Carlo simulation with the second gen Threadripper CPUs. Equally expected the 2950X is slightly faster than the 1950X, shaving two% off the completion time. The 2990XW however is slower than the 2950X, basically matching the previous generation sixteen-core part, and so a disappointing consequence in that location.

AMD's Ryzen architecture has always excelled for decompression work and we encounter that the 2990WX is no exception, absolutely smashing the seven-Null 32MB dictionary decompression test with a throughput of 187,000 MIPS. That said it was simply 31% faster than the 2950X despite packing 100% more cores. All the same AMD'due south SMT implementation works wonders in this examination and as a result the 2990WX was 116% faster than the Core i9-7980XE. But as impressive as the decompression performance is, pinch performance leaves a lot to exist desired.

For compression work the Core i9-7960X was nine% faster than the 2950X which isn't bad for AMD, and it was prissy to see the 2950X providing an viii% heave over the 1950X. The 2990WX though, well information technology fell into a heap. Despite 100% core utilization throughout the examination performance was less than that of the 1920X and just 23% higher than the 8-core 2700X. This retentiveness sensitive test gives us our first skilful look at how poorly things can go for the 2990WX, information technology'southward pretty ugly and short of shutting cores off there appears to be no fix. I'll wait at this issue more closely in a moment, for now let's continue with the application benchmarks.

VeraCrypt provides a congenital-in benchmark that allows users to exam out how the various encryption algorithms perform on a given system. These tests aren't run from local storage but rather in system memory and this proved to be a problem for the 2990WX. At present delight note this benchmark uses 100% of the 2990WX, all 64-threads are fully loaded, so the odd operation isn't a result of under utilization, though even then if that was the case information technology should at least friction match the 2950X.

The trouble is what we accept here is another retention intensive benchmark, though I should annotation it'southward not that memory intensive. The 50MB test only loads simply 50MB'south of data into the arrangement retentivity then this has little impact on the 2990WX, even and then it was all the same slower than the 2950X and even the 1950X.

The 1GB buffer test loads 1GB worth of data into the system retentivity and this proves to be a massive issue for the 2990WX, as information technology's 32-cores become choked to the bespeak where they're significantly slower than the 2950X, offer half the performance. That'due south pretty shocking to see.
