Stock CPU Performance: Legacy Tests

We have also included our legacy benchmarks in this section, representing a stack of older code for popular benchmarks.

All of our benchmark results can also be found in our benchmark engine, Bench.

3DPM v1: Naïve Code Variant of 3DPM v2.1

The first legacy test in the suite is the first version of our 3DPM benchmark. This is the ultimate naïve version of the code, as if it was written by scientist with no knowledge of how computer hardware, compilers, or optimization works (which in fact, it was at the start). This represents a large body of scientific simulation out in the wild, where getting the answer is more important than it being fast (getting a result in 4 days is acceptable if it’s correct, rather than sending someone away for a year to learn to code and getting the result in 5 minutes).

In this version, the only real optimization was in the compiler flags (-O2, -fp:fast), compiling it in release mode, and enabling OpenMP in the main compute loops. The loops were not configured for function size, and one of the key slowdowns is false sharing in the cache. It also has long dependency chains based on the random number generation, which leads to relatively poor performance on specific compute microarchitectures.

3DPM v1 can be downloaded with our 3DPM v2 code here: 3DPMv2.1.rar (13.0 MB)

x264 HD 3.0: Older Transcode Test

This transcoding test is super old, and was used by Anand back in the day of Pentium 4 and Athlon II processors. Here a standardized 720p video is transcoded with a two-pass conversion, with the benchmark showing the frames-per-second of each pass. This benchmark is single-threaded, and between some micro-architectures we seem to actually hit an instructions-per-clock wall.

    Thank you for your Great reviews.
    Look like we should not ecpect much from those new 10nm CPU's for cunsumers for new future, maybe in Q1 2020 with 10++ gen.
    2019 going to be on AMD's Favor!.

    12 or 16 core Ryzen with a 13% IPC increase, at equivalent power to the i9-9900k is not going to go well for Intel. Seems like they'll be able to compete with the AMD processors of 2019 around late 2020 at the earliest. Reply

    Take a look at the Spec 2006 benchmark and make the comparation to A76 (Snapdragon 855) it beats this Intel SKU (@2.2 GHz) In most cases with only half the power used. When SVE NEON SIMD lies in CISC is doomed. Reply

    Unfortunately we don't know how perform AMD new cpus, only cherry picked results nothing more.
    Even less we know about power consumption. Are we certain AMD 7nm cores will are winner over 12nm ones?? AMD is unhappy about clock speed for example, so the IPC advantage will be likely vanished.
    IMO AMD is painting a too bright future to be trusted. TSMC process is not perfect at all, instead of Nvidia should be on it right now.

    Lying about future products is grounds for lawsuits from shareholders (and possible criminal charges many places), so that's quite unlikely. We do have one indication of power draw from Zen2, from the live Cinebench demo where an 8-core Zen2 chip matched the 9900K's score at ~50W lower power. Of course we don't know how clocks will scale, nor the clock speed that test was run at, and it's relatively well established that Cinebench is a workload where AMD does well. Still, TSMC 7nm is proven good at this point, with several shipping large-scale SKUs on it (Apple A12, A12X, among others). Even if these are all mobile low-power chips, they're very high performance _and_ low power, which ought to fit Zen2 well. Also, the Cinebench score matching the 9900K means that either IPC has improved massively, SMT scaling on Zen2 is ~100%, or clocks are quite high. Likely it's a mix of all three, but they wouldn't reach that score without pretty decent clocks. Reply

    Ignoring any Zen IPC improvement whatsoever, process improvements alone this year would make them competitive with Intel going forward. All they need to do is ramp up the clock frequency a bit without a TDP penalty and they have an automatic win... Reply

    Icelake desktop will be out 3q 2020 from what I hear. We will have another 14nm refresh before then though. Reply

    Intel ice Lake for performance laptops should be out by 2019 christmas. Then we will see if there are any IPC improvements in this new architecture. Probably not much... Reply
