CPU Benchmarks: Real World
All of our benchmark results can also be found in our benchmark engine, Bench.
Agisoft Photoscan 1.3.3: link
The concept of Photoscan is about translating many 2D images into a 3D model – so the more detailed the images, and the more you have, the better the final 3D model in both spatial accuracy and texturing accuracy. The algorithm has four stages, with some parts of the stages being single-threaded and others multi-threaded, along with some cache/memory dependency in there as well. For some of the more variable threaded workload, features such as Speed Shift and XFR will be able to take advantage of CPU stalls or downtime, giving sizeable speedups on newer microarchitectures.
NAMD 2.13 (ApoA1): Molecular Dynamics
One of the popular science fields is modeling the dynamics of proteins. By looking at how the energy of active sites within a large protein structure over time, scientists behind the research can calculate required activation energies for potential interactions. This becomes very important in drug discovery. Molecular dynamics also plays a large role in protein folding, and in understanding what happens when proteins misfold, and what can be done to prevent it. NAMD, or Nanoscale Molecular Dynamics, has already been used in extensive Coronavirus research on the Frontier supercomputer. Typical simulations using the package are measured in how many nanoseconds per day can be calculated with the given hardware, and the ApoA1 protein (92,224 atoms) has been the standard model for molecular dynamics simulation.
Blender 2.83 LTS: Link
One of the popular tools for rendering is Blender, with it being a public open source project that anyone in the animation industry can get involved in. This extends to conferences, use in films and VR, with a dedicated Blender Institute, and everything you might expect from a professional software package (except perhaps a professional grade support package). With it being open-source, studios can customize it in as many ways as they need to get the results they require. It ends up being a big optimization target for both Intel and AMD in this regard.
Corona 1.3: Link
Corona is billed as a popular high-performance photorealistic rendering engine for 3ds Max, with development for Cinema 4D support as well. In order to promote the software, the developers produced a downloadable benchmark on the 1.3 version of the software, with a ray-traced scene involving a military vehicle and a lot of foliage.
POV-Ray 3.7.1: Link
A long time benchmark staple, POV-Ray is another rendering program that is well known to load up every single thread in a system, regardless of cache and memory levels. After a long period of POV-Ray 3.7 being the latest official release, when AMD launched Ryzen the POV-Ray codebase suddenly saw a range of activity from both AMD and Intel, knowing that the software (with the built-in benchmark) would be an optimization tool for the hardware.
We have a couple of renderers and ray tracers in our suite already, however V-Ray’s benchmark came through for a requested benchmark enough for us to roll it in. Built by ChaosGroup, V-Ray is a 3D rendering package compatible with a number of popular commercial imaging applications, such as 3ds Max, Maya, Undreal, Cinema 4D, and Blender.
HandBrake 1.32: Link
Handbrake is a favored tool for transcoding, with the later versions using copious amounts of newer APIs to take advantage of co-processors, like GPUs. It is available on Windows via an interface or can be accessed through the command-line, with the latter making our testing easier, with a redirection operator for the console output. We take the compiled version of this 16-minute YouTube video about Russian CPUs at 1080p30 h264 and convert into a 480p30 ‘Discord’ format.
7-Zip 1900: Link
The first compression benchmark tool we use is the open-source 7-zip, which typically offers good scaling across multiple cores. 7-zip is the compression tool most cited by readers as one they would rather see benchmarks on, and the program includes a built-in benchmark tool for both compression and decompression.
Algorithms using AES coding have spread far and wide as a ubiquitous tool for encryption. Again, this is another CPU limited test, and modern CPUs have special AES pathways to accelerate their performance. We often see scaling in both frequency and cores with this benchmark. We use the latest version of TrueCrypt and run its benchmark mode over 1GB of in-DRAM data. Results shown are the GB/s average of encryption and decryption.
WinRAR 5.90: Link
For the 2020 test suite, we move to the latest version of WinRAR in our compression test. WinRAR in some quarters is more user friendly that 7-Zip, hence its inclusion. Rather than use a benchmark mode as we did with 7-Zip, here we take a set of files representative of a generic stack – a micture mixture of compressible and incompressible formats

Why, for the integrated tests, are you showing 360pMin and 1080pMax?
One of those I’m never going to use, and the other I’m not going to expect an IGPU to deliver.
Sure the 1080pMax is good to know but why not pick something sensible, like 1080pMin or 720pMedium, to suggest a setup people might actually want to know about?
lucasdclopes – Wednesday, December 16, 2020 – link
I entered the comment section to say the same thing. For IGP 1080pmax is too much but 360p/600plow is too little. Needs a 768p medium.
StevoLincolnite – Wednesday, December 16, 2020 – link
Yeah. Also agree. 720P is what I would be targeting if I intend to game on integrated graphics.
360P/480P and 1080P are not my use cases/expectations.
n13L5 – Saturday, January 16, 2021 – link
Yeah, this test was done for or by a theoretical person, not a gamer, who would want to use values that give them an idea if it was going to be useful for gaming or not.
I also missed the GTX 1650, just to see how APUs compare to the cheapest *modern* card you can buy at $160 or so (unless there’s a bitcoin mining boom).
Granted, if you buy an $160 GPU, and keep in the price range of the 4750G, you’d need to find a used i5-7xxx or so on eBay for under $100.
But that would surely run better than anything they tested here, other than the GTX-1080…

I’d argue 768p is a weird resolution in context of these chips, as I’d expect them to be used with an external display. In games, if you’re using a lower resolution, I think 720p makes more sense anyhow.
n13L5 – Wednesday, December 30, 2020 – link
Even though, people do play and benchmark these on YT @1080p with somewhat reduced settings.
Its not horrible looking, but obviously no ray tracing there…

Tests “World’s best APUs”, but does not include Apple M1??
Tomatotech – Wednesday, December 16, 2020 – link
I admire the M1 but it isn’t an APU. That APU name is just AMD’s branding and only applies to their chips.
(intel’s IGPUs aren’t tested here either.)
nandnandnand – Wednesday, December 16, 2020 – link
Hogwash. If Intel makes a CPU with a faster iGPU than AMD, then it’s a better APU. Period.
Technically, the Xbox Series X and PS5 have the world’s best APUs. But good luck running your own OS on them.
ricebunny – Wednesday, December 16, 2020 – link
Actually, the review does include a soldered Intel iGPU of Tiger Lake family. Plus a Broadwell family desktop CPU.
@Ian: Can you specify in more detail per game what the max settings are?
Assuming that for Civ6 that means Ultra settings (by default without AA), I get 33 FPS on the M1 mini. That’s 65% faster than the 4750G and entirely playable.
