How the Number of CPU Cores Affects Assassin's Creed Odyssey PC Performance
By Jon Sutton on October 5th, 2018 at 05:11pm - original article from game-debate

After our initial run through Assassin's Creed Odyssey earlier today, one thing was immediately apparent - Ubisoft's new open-world adventure likes to burn through CPU resources like nobody's business. Naturally, we wanted to know exactly how demanding on the CPU Assassin's Creed Odyssey actually is. So, we put AC: Odyssey through its paces in a series of benchmark tests designed to simulate various different processors.

Following our GPU benchmarks earlier today, today we're looking at the impact CPU core count has on AC Odyssey's performance. Recent Assassin's Creed games have been incredibly taxing on processors, and we're eager to find out if this is still the case.

The processor we're using is the 6-core/12-thread Intel Core i7-5820K, running at stock clock speeds (3.3GHz base). The number of cores and threads utilised by the Intel Core i7-5820K were then tweaked in order to simulate performance on weaker CPUs.

Suffice to say, Assassin's Creed Odyssey loves to guzzle CPU resources. Whatever we threw at it, AC Odyssey will chew on down. The 6C/6T benchmark is also a little deceptive. Despite ultimately offering the same average FPS as 6C/12T, the frame rate swings were wild in comparison.

It should also be noted that in several of these benchmark tests, including the 6C/6T test, the lowest frame rate hit was 0 frames per second. This manifests in a second or two of hitching wherein Assassin's Creed Odyssey is unplayable. Only the 6C/6T and 4C/4T tests could be reliably played without the entire game hanging for a couple of seconds. Suffice to say, your CPU is going to be a huge factor in how AC Odyssey runs on your gaming PC.

This leads us to the assumption that Assassin's Creed Odyssey's minimum and recommend processors area little out of whack. The minimum Core i5-2400 is quad-core CPU without multithreading, and we can see this will almost certainly negatively affect performance. Likewise too with the quad-core, multi-threaded Core i7-3770 which is recommended. While this CPU won't prove too detrimental in terms of performance, it may struggle with high frame rates. Our 4C/8T benchmark was one of only two benchmark tests that didn't hit 0fps at any point though, so this CPU should just about do the job.

For those of you who've picked up Assassin's Creed Odyssey already, how are you finding the performance so far? Is your CPU up to the job or are you experience frame rate issues in AC Odyssey? Let us know below!
