How Does CPU Cache Size Affect Performance | Overclockers UK

www.overclockers.co.uk

There are three levels of cache: L1, L2, and L3. L1 cache is the smallest but fastest, located closest to the cores of the CPU. It holds the most critical data for immediate use. L2 cache is slightly larger and a bit slower, typically shared between two cores, and stores data that’s still important but not as urgent. L1 cache is the smallest but fastest and sits closest to the cores holding the most critical data. L2 cache is slightly larger and a bit slower, typically shared between two cores. L3 cache is the largest, shared among all cores, and holds data that might be needed soon but isn’t as time sensitive. There are three levels of cache: L1 is the smallest and fastest, L2 is slightly larger and a bit slower, and L3 is the largest and shared among all CPU cores. These are different levels of cache. L1 is the smallest and fastest, located directly on the CPU core, while L2 and L3 are larger and slightly slower, with L3 being shared between all cores.

Does CPU Cache Matter for Gaming Performance?

AMD’s 3D V-Cache processors add a large amount of L3 cache using vertically stacked silicon. This dramatically increases the cache available to a group of cores without making the main CPU die much larger. Many games respond well because their working data is more likely to remain on-chip. That is why cache-focused Ryzen X3D processors frequently rank among the best AMD gaming CPUs. The technology still has tradeoffs. Product generations differ in clock behavior, thermal design, core layout, and productivity performance. Two CPUs with 32MB of L3 cache can have different core architectures, latency, clocks, memory controllers, and core counts. No. More L3 can help, but architecture, latency, clocks, cores, memory, and game behavior matter. It gives the CPU a much larger L3 cache, increasing the chance that frequently used game data stays close to the cores instead of being retrieved from slower RAM.

For desktop and server CPUs in 2024–2025, L3 remains the last on-die cache level in mainstream architectures. The following table benchmarks typical latencies for current-generation architectures (Architecture Year 2024/2025).

L1 ~1ns, L2 ~3ns, L3 ~10ns. RAM ~80ns. Bigger cache = better gaming. Here's why. Shop gaming PCs, laptops, components & peripherals at Evetech South Africa. Custom-built desktops, top brands, unbeatable prices. Trade-off: slightly lower productivity performance. In compute-heavy non-gaming workloads, the slight clock penalty means non-X3D variants pull ahead. Trade-off: thermal headroom is tighter because the stacked die complicates heat removal. For most gamers in 2026, the Ryzen 7 9800X3D is the single best gaming CPU available — combining 96MB L3 with high clocks and proper thermal behaviour thanks to AMD's second-generation V-Cache layout. Practical buying advice: if you're primarily gaming, X3D variants are worth the premium. If you primarily edit video, render, or do CPU-heavy productivity, non-X3D variants with higher clocks and equal or more cores can outperform X3D for the same budget.

What is CPU cache, and why is it so important for gaming? - Digital ...

L3 cache is a big deal: It’s shared between some or all cores within a CPU, and it’s big. The 7950X3D, for example, has 128MB of L3 cache with its bolted-on 3D V-Cache, while it only has 16MB of L2 cache. The latency of L3 cache is even worse than L2, but having a large L3 cache is really important to prevent the CPU from needing to ask the RAM for needed data. Cache has its own hierarchy, or cache levels, which are split into L1, L2, and L3 cache. However, larger caches have higher latency, which means it takes more time for communication to happen between the CPU core and the cache. When CPUs want to accomplish things in a matter of microseconds or even nanoseconds, the slightly higher latency of L2 cache does matter. If a CPU can’t find requested data within L2 cache, it asks the next level: L3. We’ve seen a trend toward more cache for gaming in recent years.

Milan X shows an advantage in the 15k to 100k cell per core range over regular Milan, while Genoa X has an advantage in the 10k to 200k cell per core range over regular Genoa. This makes both products a viable choice for the cell count range of 2M to 13M and 1M to 20M, respectively. Figure 6 illustrates the L3 cache miss ratio obtained for different meshes and a variety of computing systems, including platforms equipped with 64-core CPUs (Figure 6a) as well as 96- and 128-core CPUs (Figure 6b). Figure 6a shows that the L3 cache miss ratio follows a similar trend for systems with 64-core Rome, Milan, and Genoa CPUs. In this case, the L3 miss rate starts at around 10%-15% for the smaller mesh and consecutively grows to 80% for the larger ones. These three platforms offer 256 MB of L3 for a single processor, thus featuring convergent L3 miss trend. In contrast, the Milan X – which offers 768 MB of L3 cache capacity per CPU – reduces the L3 miss rate for larger mesh sizes. Figure 6b demonstrates the L3 miss rate obtained for platforms with 96-core Genoa CPUs, 96-core Genoa X CPUs and 128-core Bergamo CPUs. As expected, the best L3 cache miss ratio trend is notable for the platform with 3D V-cache technology (Genoa X) compared with regular Genoa and Bergamo-based solutions.
