Gaming Tests: Far Cry 5
The fifth title in Ubisoft's Far Cry series lands us right into the unwelcoming arms of an armed militant cult in Montana, one of the many middles-of-nowhere in the United States. With a charismatic and enigmatic adversary, gorgeous landscapes of the northwestern American flavor, and lots of violence, it is classic Far Cry fare. Graphically intensive in an open-world environment, the game mixes in action and exploration with a lot of configurability.
Unfortunately, the game doesn’t like us changing the resolution in the results file when using certain monitors, resorting to 1080p but keeping the quality settings. But resolution scaling does work, so we decided to fix the resolution at 1080p and use a variety of different scaling factors to give the following:
- 720p Low, 1440p Low, 4K Low, 1440p Max.
Far Cry 5 outputs a results file here, but that the file is a HTML file, which showcases a graph of the FPS detected. At no point in the HTML file does it contain the frame times for each frame, but it does show the frames per second, as a value once per second in the graph. The graph in HTML form is a series of (x,y) co-ordinates scaled to the min/max of the graph, rather than the raw (second, FPS) data, and so using regex I carefully tease out the values of the graph, convert them into a (second, FPS) format, and take our values of averages and percentiles that way.
If anyone from Ubisoft wants to chat about building a benchmark platform that would not only help me but also every other member of the tech press build our benchmark testing platform to help our readers decide what is the best hardware to use on your games, please reach out to ian@anandtech.com. Some of the suggestions I want to give you will take less than half a day and it’s easily free advertising to use the benchmark over the next couple of years (or more).
As with the other gaming tests, we run each resolution/setting combination for a minimum of 10 minutes and take the relevant frame data for averages and percentiles.

Cage of their own making: I like that phrase. Well, I think for Intel, the best path is to design a microarchitecture from scratch, which I'm sure they're doing. Possibly Intel Israel. Sunny Cove, descending all the way from P6, is not holding up any more.Zim - Sunday, March 7, 2021 - link
Time to be me some more AMD stock.alhopper - Sunday, March 7, 2021 - link
What an awesome deep-dive technical expose/review of this processor. No stone left un-turned - incredibly detailed investigation and easily understood explanations. With this level of detail every reader can make up their own mind about the pros/cons of this product - there's no need for me to offer an opinion.Many thanks for this well written treasure trove of technical information and the graphics are wonderful. Kudos to the entire team and keep up the Good Work (TM) !!

Wow how the tables have turned. I remember for AMD's Bulldozer review, which was supposed to be AMD's answer to Core, Bulldozer was similar to Rocket Lake...it consumed MORE power and was SLOWER than the competition. Well, here's to Intel making a comeback with Alder Lake, but 2021 clearly belongs to AMD.Hifihedgehog - Monday, March 8, 2021 - link
Alder Lake, just confirmed in a lineup leak to use a heavy amount of little or low power cores, first has to ensure that they get heterogenous core architecture working in the Windows scheduler. The biggest roadblock Microsoft claimed to have already fixed it with Lakefield but even after they did and additionally Cinebench, per Intel’s special emergency request, to recompile a special update to R20 after that, Lakefield was an absolute failure in performance compared to a Y-class (or M notated) Core product. Personally, I have little faith in Microsoft and I also do not expect software companies recompiling every last piece of software made in the last decade either just to accommodate a radical new design all for Intel’s sake. Developers would much rather assume a simple, vanilla core architecture than an unbalanced one with little and big cores and therein lies a huge risk factor for Intel. I foresee a huge misfire here because Microsoft isn’t exactly a good company to bet on refixing what they claimed they have already fixed with Lakefield.GeoffreyA - Monday, March 8, 2021 - link
I'm sceptical of this whole fast/slow core approach myself and believe it's a mistake. They will learn the hard way. Perhaps it works for Apple, I don't know, but Intel and AMD are better of spending their efforts in cutting down power in their ordinary cores dynamically.Hifihedgehog - Monday, March 8, 2021 - link
It works for Apple because they have a iron-tight grasp on the full stack which requires developers to use their latest compilation and development tools to get their apps to the App Store and ultimately in users’ hands. You can run pretty much anything under the sun for 2 decades plus on Windows and without a recompile, you will never utilize their cores correctly. The Windows scheduler as it stands is garbage tier compared to Linux with a plain vanilla homogenous core design so I expect very little from Microsoft unless they actually redesign their scheduler from the ground up. Don’t hold your breath on that one.GeoffreyA - Monday, March 8, 2021 - link
The whole idea smacks of Bulldozer, and that means disaster.blppt - Monday, March 8, 2021 - link
Only if their single thread performance sucks (which from all I've seen, it won't)---Bulldozer's problem was being behind in manufacturing process and requiring a highly-threaded application to shine.Hifihedgehog - Tuesday, March 9, 2021 - link
Well, the problem then is how smartly it assigns threads to the right cores and the Windows scheduler still has serious problems with that to this very day. If it doesn’t do that right, it could appear like an overclocked Core i3 in comparison to Ryzen and that is where the Bulldozer analogy is fitting. AMD banked on their unique topology getting OS and development optimization down the road—FineWine to coin a phrase—but that never materialized.
