Performance results

 

SYSmark 2014 ver 1.5

SYSmark is a business productivity benchmark suite that measures the response times of tasks on a PC using real-world applications in the areas of office productivity, media creation, and data and financial analysis. Task response times from simulated user input are used to generate a performance rating that reflects actual user experience, so the faster a PC responds to application workloads, the higher its score will be. The method of measuring response times can take many forms, such as the time it takes for an application to show a pop-up completion message, or how long it takes a progress dialog to disappear and for a user to regain application control.

The applications in SYSmark benefit to a certain extent from multiple cores (the Ryzen 7 1800X and Ryzen 5 1600X are clocked the same, but the 8-core 1800X is overall quicker), but it looks like clock speed wins out in the end, with the Core i7-7700K high starting base clock helping it inch ahead. On the other hand, the 4-core/8-thread Ryzen 5 1500X had the weakest performance because of a combination of less aggressive speeds and lower core/thread count, coming in at 18 per cent slower than the 1600X.

A look at the score breakdowns also shows that the Ryzen 7 chips excel in data/financial analysis-type tasks, which involves crunching, compressing and decompressing data to make forecasts and projections. Here, they were only behind the 10-core Intel Core i7-6950X.

 

SPECviewperf 12.1

SPECviewperf is used to measure the 3D graphics performance of systems in professional applications. Each individual workload, called a viewset, represents graphics and content from an actual real-world application. SPECviewperf actually runs a total of eight different viewsets, but we’ve picked the four which have the greatest performance variation across CPUs displayed here.

The 3ds-max viewset comes from traces of the graphics workload generated by 3ds Max 2016, while maya-04 is derived from Autodesk’s Maya 2013 application. The catia-04 viewset involves the numerous rendering modes from the CATIA V6 R2012 application, and includes things like anti-aliasing, depth of field, and ambient occlusion. Finally, the sw-03 viewset comes from SolidWorks 2013 SP1, and involves various rendering modes including environment maps.

All the Ryzen CPUs were quite closely matched here, and it’s clear that these workloads aren’t quite suited to taking advantage of high thread counts. For example, the 4-core/8-thread Ryzen 5 1500X was shown to edge out the 8-core/16-thread Ryzen 7 1700X and 1700, likely by virtue of a slightly higher base clock.

 

Cinebench R15

Cinebench R15 is a better indicator of the Ryzen’s 7 performance because of its ability to utilize up to 256 threads to evaluate a processor’s performance in a photorealistic 3D rendering. We ran both single-core and multi-threaded benchmarks to evaluate single-threaded performance and multi-threaded scalability here.

As we saw in our Ryzen 7 review, the multi-threaded benchmark is where Ryzen really steps up. The 6-core/12-thread Ryzen 7 1600X beat the Intel Core i7-7700K by a good 28 per cent, and the latter is the flagship of Intel’s mainstream CPUs line-up. That said, the extra two cores and four threads on the 1800X meant that it was still 31 per cent quicker than the 1600X

Interestingly enough, the Ryzen 5 1600X had a narrow advantage over the Ryzen 7 1800X in the single-core benchmark. Both chips have the same clock and boost speeds, but the results suggest that the 1600X was operating at the upper end of its boosted frequencies more often.

 

Handbrake 1.0.2

Handbrake is a video transcoder that converts videos into a format for use on PCs and portable electronic devices, and is a good indicator of a processor’s video encoding capabilities. YouTube content creators, Twitch streamers, and other video creators will be most interested in this performance metric.

The Ryzen 5 1600X did well here and performed closer to the Ryzen 7 chips with relatively quick encoding times. However, the Ryzen 5 1500X was quite a bit slower here, which is probably why AMD isn’t recommending this particular CPU for streamers as it is with the 1600X.

Streaming is very CPU-intensive, and having more cores and threads help gamers take less of a performance hit while broadcasting.

 

Power consumption

To test power, we ran the energy-01 viewset in SPECviewperf 12.1 and recorded the peak power consumption.

The most notable difference here would be from the lower 65 watt TDP of the Ryzen 5 chips, which translated into a peak power consumption that was around 30 watts lower than the 95 watt Ryzen 7 parts.
