Picking the right CPU has a big effect on how well games run, especially at high frame rates, where delay, cache behavior, and architecture design are very important.

The Ryzen 7 9800X3D, Ryzen 9 9950X3D, Core i9-14900KS, and Core Ultra 9 285K are four of the most powerful gaming processors from AMD and Intel.

This test uses 11 games across different screen resolutions and both standard benchmarks and the Gaming Quality IndexTM to find the CPU that delivers the most reliable, high-quality gaming experience.

Gaming Experience

The CPU you choose affects more than just FPS; it changes how you play games in general. The CPU's architecture is very important for speed. All cores, cache, and I/O are on a single silicon die in a monolithic CPU, like Intel's 14900KS.

This helps cut down on delay. Chiplet- and tile-based designs, like AMD's 9800X3D and Intel's 285K, spread parts across multiple dies, which slows die-to-die contact.

The quality of the Integrated Memory Controller (IMC) also affects how quickly frames are rendered in fast-paced games.

AMD addresses chiplet latency with 3D V-Cache, which greatly increases the amount of available L3 cache. This reduces the number of memory accesses the system needs during gameplay, improving overall speed.

How AMD 3D V-Cache Improves Gaming

Why AMD 3D V-Cache Is Better. Multi-level caching (L1, L2, L3) is what gaming CPUs use to store data and retrieve it quickly. Even though it is slower than L1 and L2, the L3 cache is much larger and stores data that can be reused across frames.

AMD's 3D V-Cache adds an extra L3 layer on top of the CPU cores, making it easier to access important gaming data faster and reducing the delay in games that use cache.

This technology works especially well in games where the same assets need to be displayed repeatedly. This makes frame consistency much better.

Traditional Performance Metrics: Average FPS & 1% Lows

In the past, benchmarking has mostly focused on average FPS and the 1% low FPS. The 1% low shows the performance floor, and the average FPS shows the average frame rate.

The 1% low also shows frame rate dips that can affect smoothness. To find the 1% low, you have to sort frame times from slowest to fastest and find the one that is longer than 1% of the total benchmark length.

These measures are useful, but they don't fully describe how fluid the gameplay is. This is why a more complete metric was created.

Gaming Quality IndexTM (GQI)

The Gaming Quality IndexTM measures the quality of gaming by looking at two main things: how fun the game is to play and how stable the frame rate is. It looks at the difference between average FPS and 1% lows.

It compares 1% lows to a 60 FPS benchmark, which is generally considered the minimum for smooth gameplay. It's easier to see total performance rather than just raw speed when the gap between frames is smaller.

This is because Test Setup & Hardware Configuration. High-end computers were set up to allow fair comparisons during benchmarking. Intel CPUs were tested on ROG Apex Encore and MSI Unify-X boards, which were selected for their ability to keep memory stable in high-speed setups.

AMD X3D CPUs were tried on ROG Crosshair Hero and Apex motherboards. For AMD AM5, DDR5-8000 was chosen; DDR5-8200 for Intel 14900KS; and DDR5-9000 for Intel 285K in Gear 2 mode.

Thermal Grizzly graphene cryosheets were used to cool all systems paired with an RTX 5090 Astral GPU. Performance changes were made to all systems in the same way.

Benchmarks were done at three different resolutions to cover a range of game situations. At 1080p Low, the CPU was put through its hardest test.

In competitive games, 1440p Medium showed a balanced CPU/GPU load, and 4K Ultra showed situations where the GPU was fully loaded. A new game, Marvel Rivals, was also added because it has built-in measurement features.

Benchmark Overview

A look at several games, such as Shadow of War, Horizon Zero Dawn, and Black Myth, revealed several patterns. AMD won all 1080p tests by using 3D V-Cache to lower delay and improve 1% lows.

In 4K resolutions, where the GPU was slowing things down, Intel beat AMD because it could reach memory more quickly. The 285K performed very well at 1% low performance at high resolutions, demonstrating how well its thread scheduling and fabric performance can work when properly configured.

How to Unlock Maximum CPU Performance

To get the best CPU speed, platform-specific tuning was needed. When using a +200 MHz Max CPU Boost Override, allowing PBO, setting a PBO scaler of 2x, and using a -35 all-core curve optimizer with EXPO enabled (CL36, tREFI 65535) and Windows High Performance power plan on AMD's 9800X3D, performance went up by about 10% and latency went down by 30%.

The 9950X3D needed similar tweaks, with a few small differences, to achieve about a 13% speed boost and the same reduction in latency.

In AMD's Turbo Game Mode for dual-CCD X3D processors, the non-V-Cache CCD and SMT are disabled, prioritizing low latency. This mode makes 1% lows much better in games like F1 2024 at 1440p and 4K.

Intel CPUs were also tweaked to work at their best. The 14900KS got better speed and lower latency thanks to ASUS Multi-Core Enhancement, XMP at CL38 with VDD/VDDQ at 1.41V, tREFI 65535, and the Windows High Speed plan.

These features helped remove limits (up to 90°C), and they were combined with the Windows High Performance plan. To achieve an 11% performance boost and a 30% reduction in latency for the Core Ultra 9 285K, the P-core and E-core ratios, ring clocks, NGU fabric, D2D interface, MSI Extreme BIOS preset, and XMP settings had to be fine-tuned.

When Intel changed its Application Performance Optimizer (APO) in 2025, it made big differences. APO doubled 1% lows in Total War: Warhammer III on the 285K, but it didn't have much of an effect on other games. In eight out of eleven games, the 14900KS showed improvements. It worked better than turning off E-cores and kept showing improvements even at higher resolutions.

Final Thoughts

About 52% of standard raw FPS benchmarks were won by AMD CPUs. They performed best at 1080p and on medium settings, where CPU load is highest, and V-Cache performs best.

The Gaming Quality IndexTM tells a slightly different story when used to rate the general gameplay experience: 53% of the time, Intel CPUs were better.

They were best at 1440p and 4K, where RAM speed and IMC performance were more important. When properly set, the 285K really stood out for its 1% low stability.

Both AMD and Intel offer great speed, but their strengths make them better for different types of gaming. AMD's X3D CPUs (9800X3D and 9950X3D) are great for competitive 1080p games with high refresh rates because they have low delay and smooth 1% lows.

It's perfect for e-sports and games that use a lot of CPU power. With better memory modules and real APO improvements, Intel's 14900KS and 285K really shine at higher resolutions. When tuned for maximum performance, the 285K has a lot of promise.
