Marrying Vega and Zen: The AMD Ryzen 5 2400G Review
by Ian Cutress on February 12, 2018 9:00 AM ESTBenchmarking Performance: CPU Encoding Tests
One of the interesting elements on modern processors is encoding performance. This includes encryption/decryption, as well as video transcoding from one video format to another. In the encrypt/decrypt scenario, this remains pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security. Video transcoding as a tool to adjust the quality, file size and resolution of a video file has boomed in recent years, such as providing the optimum video for devices before consumption, or for game streamers who are wanting to upload the output from their video camera in real-time. As we move into live 3D video, this task will only get more strenuous, and it turns out that the performance of certain algorithms is a function of the input/output of the content.
All of our benchmark results can also be found in our benchmark engine, Bench.
7-Zip 9.2: link
One of the freeware compression tools that offers good scaling performance between processors is 7-Zip. It runs under an open-source licence, is fast, and easy to use tool for power users. We run the benchmark mode via the command line for four loops and take the output score.
7-zip gives two contrasting stories here. For compression, full cores are needed to get the best performance, with frequency helping as well. However, for decompression, the extra threads help a lot. The combined result looks more like the decompression score, with the Ryzen 5 2400G sitting between the six-core Core i5-8400 and the quad-core Core i3-8350K.
WinRAR 5.40: link
For the 2017 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 (33 video files in 1.37 GB, 2834 smaller website files in 370 folders in 150 MB) of compressible and incompressible formats. The results shown are the time taken to encode the file. Due to DRAM caching, we run the test 10 times and take the average of the last five runs when the benchmark is in a steady state.
WinRAR is a good scaler with cores, frequency, and memory performance. The eight threads and DDR4-2933 contributes a good amount to the performance here, especially in light of where AMD was. The jump from the Ryzen 5 1400 to the 2400G is also noticable, due to the uptick in frequency and memory speed. The high single-thread performance of the Intel cores still wins out, however.
AES Encoding
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.
HandBrake v1.0.2 H264 and HEVC: link
As mentioned above, video transcoding (both encode and decode) is a hot topic in performance metrics as more and more content is being created. First consideration is the standard in which the video is encoded, which can be lossless or lossy, trade performance for file-size, trade quality for file-size, or all of the above can increase encoding rates to help accelerate decoding rates. Alongside Google's favorite codec, VP9, there are two others that are taking hold: H264, the older codec, is practically everywhere and is designed to be optimized for 1080p video, and HEVC (or H265) that is aimed to provide the same quality as H264 but at a lower file-size (or better quality for the same size). HEVC is important as 4K is streamed over the air, meaning less bits need to be transferred for the same quality content.
Handbrake is a favored tool for transcoding, and so our test regime takes care of three areas.
Low Quality/Resolution H264: Here we transcode a 640x266 H264 rip of a 2 hour film, and change the encoding from Main profile to High profile, using the very-fast preset.
High Quality/Resolution H264: A similar test, but this time we take a ten-minute double 4K (3840x4320) file running at 60 Hz and transcode from Main to High, using the very-fast preset.
HEVC Test: Using the same video in HQ, we change the resolution and codec of the original video from 4K60 in H264 into 4K60 HEVC.

Here's an article with a bunch of graph's that include the i7-5775C if you'd prefer to peep this instead of that vid.https://hothardware.com/reviews/amd-raven-ridge-ry...

Your i7-5775C isn't even as fast as an old Kavari A10 w/ 512 GCN2 SP's (it's close, but no cigar), so vs Vega 8 & 11 it gets it's ass absolutely handed to it... like by a lot - https://youtu.be/sCWOfwcYmHIjrs77 - Monday, February 12, 2018 - link
When I look at all the available benchmarks so far, then there's nothing this chip can play, that I can't allready play with my 5775C. 1080p with medium settings is no problem for most games like Overwatch, Borderlands, WoW, Diablo, etc. So if the 2400G can't run them at high settings, like it looks like, then I see no reason to call it the King of integrated graphics really.Holliday75 - Monday, February 12, 2018 - link
How on God's green Earth can you compare a $600+ CPU versus the 2400g? The whole point of iGPU is to be cheap. The 2400g out performs a CPU that costs over 3x as much in the exact area this chip was built for. Low end gaming.jrs77 - Monday, February 12, 2018 - link
$600 ?!? I paid €400 for my 5775C incl 24% VAT. So that would be $300 then.And again. I can play games in 1080p with low to medium settings just fine, so I don't see a reason to upgrade.

Need to check your math. €400 = $491.jrs77 - Tuesday, February 13, 2018 - link
Back when I bought it, the Euro and the Dollar where allmost 1:1, and to get the Dollar-price you need to subtract the 24% VAT I pay over here, so yeah, back then it was around $300. Hell, the intel list-price was $328.SaturnusDK - Wednesday, February 14, 2018 - link
So what you're saying is that you paid twice the money to have under half the graphics performance and 20% lower CPU performance of a 2400G.Graphics-wise the 5775C was pretty bad and got beaten by ALL AMD APUs at the time. It was close but it was never very good. Time has not been kind to it.

I noticed with some sadness that there's no DOTA 2 benchmarks. Was this due to time constraints or unforeseen issues? I'm crossing my fingers that DOTA 2 hasn't been dropped for good as it's a great benchmark for silicon such as this, though the other benchmarks of course do let us ballpark where it would land.Ian Cutress - Monday, February 12, 2018 - link
That's in our GPU reviews; different editors with different benchmark sets. We're looking at unifying the two.
