AMD Ryzen 7 5800X3D review: Cache Finance

The $449/429 lb Ryzen 7 5800X3D is something a little different from AMD, a processor that’s there to show off the power of the company’s 3D V-Cache design for upcoming Ryzen processors and battle the Intel 12900 KS for the title of “fastest gaming processor.” It’s also the latest version of the surprisingly long-lived AM4 platform, which debuted in 2017 and lasted six generations of Intel as Ryzen processors improved by leaps and bounds.

So what exactly is 3D V-Cache? Let’s start with the basics. You can think of a CPU cache as a place to store the data you’re currently working on – a bit like RAM, but because it’s inside the CPU, it’s faster in size And On a smaller scale in terms of the amount of data that can be stored. Modern processors typically use three levels of cache – L1, L2, and L3 – with L1 cache being the fastest to access but the smallest, L2 slower but larger, and L3 the slowest and slowest. This is the third level of cache that AMD has changed, moving from a traditional 2D design to a 3D design, a cache stack that takes up more vertical space. This allows a lot of data to be stored inside the processor at once, which increases the chances of the required data actually being inside and speeds up any subsequent processing.

AMD is supposed to use this technology in future Zen 4 processors, but here and now that’s just the proprietary 5800X3D, which is an upgraded version of the Ryzen 7 5800X launched in 2020. Compared to the 5800X, the 5800X3D trades in with a slightly higher frequency and fewer controls Overclocking a much larger 96MB L3 cache — three times the size of the 5800X.

Before we get into the first test results, let’s briefly review the facility we are using. For AMD, we’re using the Asus ROG Crosshair 8 Hero, while the 11th generation Intel gets the Asus ROG Maximus Z590 Hero and the 12th generation gets the Asus ROG Z690 Maximus Hero — all the advanced motherboards for their platforms. DDR4 motherboards used G.Skill 3600MT/s CL16 memory, while 12th Gen Intel got the advantage of a faster Corsair 5200MT/s CL38 RAM but with higher payback.

AMD’s 11th generation Intel processors were cooled with a 240mm AiO Eisbaer Aurora, while the 12th generation tests were run with an Asus ROG Ryujin 2 360mm AiO. (And to answer the obvious question: AiOs 240mm and 360mm hinges tend to provide equivalent performance based on our tests—particularly for an outdoor test bench in cool (21°C) ambient conditions. The only difference tends to be the fan speed, which is higher at 240 mm by 360 mm.) Our facility is finished with a 1000W Corsair RM1000x power supply from Infinite Computing.

To reduce the variance between on and off and make sure we’re as limited in the processor as possible, we’re using the Asus ROG Strix 3090 OC Edition. This is a massive 3-slot design and a triangular fan that keeps the card surprisingly cool and quiet.

One of the biggest questions about the 5800X3D is exactly where the upgraded cache will be useful – because if it’s a game or other application that doesn’t fit a certain performance profile, it may not show any performance advantage over the 5800X3D – and in fact, it may perform worse due to The clock speed that AMD sacrificed for design work.

To find out, we tested the 5800X3D in a variety of content creation and gaming scenarios — compared to the original 5800X and a number of other recent AMD and Intel processors. We hope to see some big performance increases, especially in video games, but we’ll start with some benchmarks for quick content creation: Cinebench R20 3D processing and Handbrake code conversion.

None of the content creation results were particularly impressive for the 5800X3D, which beats the 5600X and Intel 12400F, but lags behind previous competitors like the 12900K, 12700K, and 5800X (the latter between two and six percent). That’s not a huge surprise – none of the tasks will make any sense from holding a larger cache, so you only see the effect of the new CPU’s lower base clocks compared to the standard 5800X. However, the results are not disastrous either; It is still a processor with optimal capabilities for these tasks that surpasses previous generations, but does not lead in this category.

With those gone, let’s move on to the fun stuff: Let’s see how the 5800X3D works in a variety of games. Click the quick links below to jump to the headlines you care about most, or click the Next Page button to enter them all!
