Gaming Tests: Red Dead Redemption 2
It’s great to have another Rockstar benchmark in the mix, and the launch of Red Dead Redemption 2 (RDR2) on the PC gives us a chance to do that. Building on the success of the original RDR, the second incarnation came to Steam in December 2019 having been released on consoles first. The PC version takes the open-world cowboy genre into the start of the modern age, with a wide array of impressive graphics and features that are eerily close to reality.
For RDR2, Rockstar kept the same benchmark philosophy as with Grand Theft Auto V, with the benchmark consisting of several cut scenes with different weather and lighting effects, with a final scene focusing on an on-rails environment, only this time with mugging a shop leading to a shootout on horseback before riding over a bridge into the great unknown. Luckily most of the command line options from GTA V are present here, and the game also supports resolution scaling. We have the following tests:
- 384p Minimum, 1440p Minimum, 8K Minimum, 1080p Max
For that 8K setting, I originally thought I had the settings file at 4K and 1.0x scaling, but it was actually set at 2.0x giving that 8K. For the sake of it, I decided to keep the 8K settings.
For our results, we run through each resolution and setting configuration for a minimum of 10 minutes, before averaging and parsing the frame time data.

It could be due to x264 limiting the number of threads because when vertical resolution divided by threads drops below a certain threshold---I think round about 30 or 40---quality begins to suffer.GeoffreyA - Wednesday, March 31, 2021 - link
I tested this now on FFmpeg but it should be the same on Handbrake because the x264/5 libraries are doing the actual encoding.I only have a 4C/4T CPU but used the "-threads" switch to request more. On x264, regardless of resolution, once more than 16 threads are asked for, it logs a warning that it's not recommended but goes ahead and uses the requested count, up to 128. I assume that running at default settings, like AT is probably doing with Handbrake, will let x264 cut off at 16 by itself. If someone could confirm this with a 32-thread CPU, that would be nice. As for x265, I gave it a try as well and the encoder refuses to go on if more than 16 threads are requested, saying the range must be between 0 and X265_MAX_FRAME_THREADS.
In short, I reckon both these codecs are cutting off at 16 threads on default settings. If Ian or someone else could test how much extra is gained by manually putting in the count on a 32T CPU, that would be interesting.

Splat. Backporting doesn't really work & dead-end platform.What I'd really like to read is a detailed narrative of Intel's blunders over the last 5-10 years. To me, it probably makes a case study in failed leadership & hubris, but I would really like to read an authoritative, detailed account. I'm curious why the risks of their decisions were not enough to dissuade them to take a better path forward.

Yes, some sort of post mortem on Intel development over the last few years would be interesting. Once they abandoned the Pentium 4 madness, they did a good job with Core, Core2 and then the early stages of the 'i' series. Because AMD were by that point down their own dead end, they had essentially no competition for about a decade. The tempting easy explanation is that as a de facto monopoly for desktop and laptop CPUs, they only innovated enough to keep the upgrade cycle ticking over, then when AMD made a rapid comeback they got caught with their pants down and some genuine technical difficulties in fab tech.... But the reality could be a lot more complex and interesting than that.Hifihedgehog - Tuesday, March 30, 2021 - link
> But the reality could be a lot more complex and interesting than that.The reality is Conroe was a once-in-a-lifetime IPC improvement, literally 90% better (or nearly double the performance!) clock-for-clock than the ill-fated Pentium 4 (see here: https://www.reddit.com/r/intel/comments/m7ocxj/pen... They are not going to get that again unless Gelsinger clones himself across Intel's entire leadership team. Now, they may get something Zen-like in the ~50% range, but nothing Conroe-like unless ALL the stars align after a decade of complacency.

Keep in mind that P4 was a piece of shit built for marketing high clock speeds and was easily beaten by Athlon 64 running 1Ghz slower so getting that much IPC wasn't as hard as usual.GeoffreyA - Wednesday, March 31, 2021 - link
"Keep in mind that P4 was a piece of"Not to defend the P4, but Northwood wasn't half bad in the Athlon XP's time, beating it quite a lot. It was Prescott that mucked it all up.

TBF, the only reason it wasnt half bad is AMD's willingness to just abandon XP. I mean, only 2.23 GHz? 3 GHz OCs were not hard to do with their mobile lineup, and those obliterated anything intel would have until conroe. IF they had released 2.4, 2.6, and 2.8 GHz athlon XPs intel would have been losing every benchmark against them.GeoffreyA - Friday, April 2, 2021 - link
Oh yes, the XP had the higher IPC and would have given Intel a sound drubbing if its clocks were only higher. Thankfully, the Athlon 64 came and turned the tables round. I remember in those days my heart was set on the 3200+ Barton but I ended up with a K8 budget system of sorts.
