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.

    One issue is though that at my favored place to buy CPU's (microcenter.com) The 2200G isn't $40 more, its only $30 more. The 200GE is $49.99 and the 2200G is $79.99. Add to that you can get a B450 motherboard for $59.99. So for just $30 more for the total system price and the fact that the 2200G/B450 combo guarantees overclocking capability, I couldn't really see going with either of the CPU's in this review.

    Fully agree, and, at those prices (2200G at $ 79.99, plus mobo for $59.99), it's even more a closed and shut case. Neither the Athlon nor the Pentium come anywhere near the 2200G, especially if the iGPU is "it", which is likely for a budget system. The only scenario I can see for a builder to chose the Athlon or the Pentium is if they a. are on sale, and b. if it's for one's parents or grandparents, and all they want to do is browse the web and some occasional light office work. But, even there, if one can swing the extra $30, why not get the much more capable 2200G? With the added ability to play some games, maybe you'll visit more often (:

    I was thinking this throughout - "wow, this review is a great advertisement for the 2200G!"

    Personally I'd like to wait for a chip with AV1 support, Navi and PCIe 4.0, but it seems likely that you'll be able to upgrade to all of that at a later date if you pick your motherboard right.

    Can you put the venerable i5 2500 in the new Bench? With used systems available for $90 it's the price/performance champion.

    On the Overclocking page:

    "In recent weeks, motherboard manufacturers have been releasing BIOS firmware that enables overcooking on the Athlon 200GE."

    I know OCing can increase temperatures, but calling it overcooking might be a little strong.

    Ian,

    I think you might want to rephrase every paragraph which has "AVX" in it. From your wording it sounds like you're surprised the pentium doesn't benefit much from the use of AVX, whereas the truth is it doesn't support AVX at all, hence even if you use avx-optimized binaries it's still going to use an sse-only path.
    This is of course a reversal of the other Core chips vs. Ryzen - intel typically benefits quite a bit more from AVX code, since it actually has simd units which are physically 256bit wide, whereas Ryzen only has simd units which are 128bit wide.
  • GreenReaper - Tuesday, January 15, 2019 - link

    I agree, I was a little confused when I saw talk of AVX for the Pentium - don't get me wrong, SSE optimizations can provide great benefits (compare 'openssl speed -evp' to 'openssl speed' on a Celeron), and probably they are used by the "optimized" path but it's not going to give the same results.

    As you say, "supports" is debatable on Ryzen. But even if a CPU didn't really support it on a hardware level at all (which is not the case), its use might result in improvements due to the ability to provide a microcode equivalent than is faster than the SSE-based alternatives.
  • silverblue - Tuesday, January 15, 2019 - link

    It's not really debatable in my eyes - it may be half-speed, but there's no AVX offset - as far as I can tell - to worry about. When Zen 2 pops up, perhaps it'll have to behave more like Intel's implementation.
  • eastcoast_pete - Tuesday, January 15, 2019 - link

    Agree. After all, in the Intel universe, the absence of AVX is a key differentiator between the Pentium and the core i3; if you want hardware-supported AVX extensions, you have to fork over the extra $$$ and get at least the entry-level core chip.

    I'd like to know where one would find the G5400 at 60$, or even at the same price as the 200GE.

    I don't seem to be able to find the G5400 in Europe for less than 75€. On the other hand, I can get a 2000GE at 55-60€.

    For example, Materiel.net - one of the most popular online shops in France and Belgium, has the cheapest Intel i3, the G4900, at 67.95€, while the 200GE is 57.95€. And the G5400? They list it as 'out of stock', at more than 100€ (!)

    If both where at the same price, indeed, the Intel CPU would be more interesting. But if it's either unavailable or 20-50% more than the price given in the article, what's the point?
