UL Benchmarks introduces a new approach to CPU benchmarking with its 3DMark CPU Profile which, instead of producing a single number, shows how CPU performance scales and changes based on the number of cores and threads used.
3DMark CPU Profile consists of six tests, each of which uses a different number of threads: the benchmark starts using all available threads, then repeats using 16 threads, 8 threads, 4 threads, 2 threads and ends with a threaded test single.
These six tests help you check the performance of the CPU by comparing it with other results obtained on similar models to verify that everything is working smoothly.
3DMark CPU Profile could be very useful for overclocking enthusiasts by showing the potential of the CPU under consideration and providing more ways to track the performance gains achieved.
Simultaneous multithreading (SMT) allows each core to run more threads, and the more you have, the higher the work throughput.
However, the number of cores is increasing faster than the ability of popular applications to use them, and some tasks are better suited to multithreading and more cores than others.
A modern CPU benchmark should demonstrate the benefits of having many cores and threads scaling beyond 16 threads and how it performs on games and other real-world tasks where performance rarely scales beyond a modest number of cores and threads.
It is not possible to represent both of these aspects of CPU performance in a single number, but a different kind of approach is required.
All six tests use the same workload – it’s just the amount of threads that changes, with the tests limited to using 1, 2, 4, 8, 16, or the maximum number of threads available.
Each of the six tests produces a comparable score to the others, and a graph shows how the clock rate and CPU temperature have changed while each is running.
The green bars on the 3DMark CPU Profile results screen show how your scores rank against the best achieved: the longer the bar, the closer your score gets to the best result for your CPU model.
The average score, shown by the marker, shows the level of performance you should expect for your CPU at the default settings.
A lower score could indicate a problem with cooling or backgrounded processes and in this case the monitoring chart could help you check how the CPU temperature has changed during the test run.
The distance from the median marker at the end of the bar represents your CPU’s overclocking potential.
The Max Thread Score represents the full potential of the CPU when using all available threads.
The practical use cases for this test are not games, but extremely heavy, multithreaded workloads such as cinema-quality rendering, simulations, and scientific analysis.
Computationally intensive tasks such as digital content creation and 3D rendering benefit from more threads, but the 16-thread test score is less relevant to estimating real-world performance at play.
Modern DirectX 12 games perform at their best in multithreading beyond 4 cores and are usually more closely related to the 8 thread test score, which has a high correlation with 3DMark Time Spy’s CPU score.
The frame rates of popular esports titles such as DotA 2, League of Legends and Counter-Strike: Global Offensive, on the other hand, are more closely related to the 2 and 4 thread test scores, while the 1 thread test score is a fundamental measure of performance. processor in some older applications.
3DMark CPU Profile is now available as a free upgrade to 3DMark Advanced Edition and 3DMark Professional Edition with a valid annual license.
From now through July 8, 3DMark is 85% off, only $ 4.49 when purchased on Steam or the UL Benchmarks website.
