The Intel Core i9-13900F and AMD Radeon RX 6400 form a desktop pairing with an unusually large performance gap between the two components. The CPU sits at the 91st percentile of all CPUs with an average benchmark score of 51730, while the GPU sits at the 35th percentile of all GPUs with an average score of 6001. No measured FPS rows exist for this exact combination, so all frame-rate discussion in this analysis is estimated from the benchmark scores rather than from game-by-game measurements.

CPU Analysis

The Intel Core i9-13900F is a 24-core, 32-thread desktop processor built on the Raptor Lake architecture, specifically the Raptor Lake-S silicon. It belongs to the Core 13th Gen series and uses Intel Socket 1700. The base clock is 2000 MHz and the boost clock reaches 5.60 GHz. The CPU is manufactured at Intel’s 10 nm process and has a die size of 257 mm². Its cache layout consists of 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. Memory support covers both DDR4 and DDR5 in a dual-channel configuration, with ECC support listed as enabled. The platform provides PCIe Gen 5 with 20 lanes from the CPU. The CPU has a 65 W TDP and is listed with a locked multiplier, so it is not unlocked for overclocking.

Benchmark results show a processor with very strong single-threaded and multithreaded performance. In Cinebench R23, the CPU scores 40928 points multicore and 5778 points single-core. The multicore number reflects heavy parallel workloads such as 3D rendering, video export, and software compilation. The single-core number indicates strong responsiveness in everyday applications and in lightly threaded tasks. PassMark results reinforce this picture: the CPU scores 49693 in multithreaded testing, 4406 in single-threaded testing, 188022 in integer math, and 131007 in floating point math. Data-heavy tasks also look strong, with a PassMark data compression score of 635147 and a data encryption score of 38214.

The CPU’s average benchmark score of 51730 places it at the 91st percentile of all CPUs. Its nearest rivals by average score are the AMD Ryzen 9 5950X at 51947 with a delta of -0.4%, the Intel Core Ultra 5 235HX at 52073 with a delta of -0.7%, the AMD EPYC 8124P at 52121 with a delta of -0.7%, and the Intel Core Ultra 9 285T at 51310 with a delta of 0.8%. In other words, the i9-13900F sits within roughly 1% of a group of high-end rivals. Real-world CPU-bound work should be essentially comparable among these parts.

Benchmark Performance

The complete CPU benchmark set shows consistent scaling from two threads through the maximum thread count. 3DMark results are 1145 for single-thread, 2265 for 2-thread, 4393 for 4-thread, 7426 for 8-thread, 9957 for 16-thread, and 13985 for max-thread. Geekbench adds a multicore score of 19680 and a single-core score of 2533. Cinebench R20 reports 17189 multicore and 2426 single-core, while Cinebench R15 reports 4125 multicore and 582 single-core. These scores indicate a processor that scales well as more threads are used, which is exactly what the 24-core/32-thread configuration would predict.

The GPU presents a much weaker picture. The AMD Radeon RX 6400 has an average benchmark score of 6001 and is at the 35th percentile of all GPUs. Its individual benchmark results include a 3DMark Steel Nomad DX12 score of 176, Geekbench OpenCL of 32011, Geekbench Vulkan of 16372, PassMark G3D of 7673, PassMark G2D of 722, PassMark DirectX 9 of 93, DirectX 10 of 54, DirectX 11 of 70, DirectX 12 of 30, and GPU compute of 2812. The closest GPU rivals by average score are the NVIDIA GeForce GTX 770M at 6000 with a delta of 0%, the NVIDIA RTX PRO 6000 Blackwell Server at 5996 with a delta of 0.1%, the AMD FirePro W4100 at 5987 with a delta of 0.2%, and the NVIDIA Quadro K4000M at 5986 with a delta of 0.3%. This is statistical parity with a set of GPUs that all cluster around the 6000 score level.

The combined picture is defined by the gap between the two components. The combined percentile for this pairing is 63. That places the overall system in the middle tier of the database, but the internal split is extreme: a 91st-percentile CPU paired with a 35th-percentile GPU. The CPU carries the system’s overall benchmark standing upward, while the GPU pulls it downward.

Balance and Bottleneck

Benchmark results indicate an unbalanced pairing. The CPU is at the 91st percentile of all CPUs, while the GPU is at the 35th percentile of all GPUs. That large gap matters for workload prediction. In graphics-bound workloads, the RX 6400 will be the limiting component before the i9-13900F is challenged. Its 4 GB of VRAM, 128.0 GB/s bandwidth, and low PassMark G3D score of 7673 all point to a GPU that can only feed a modest level of graphical output. The CPU, by contrast, has abundant multithreaded compute: 40928 in Cinebench R23 multicore and 49693 in PassMark multithreaded.

In CPU-bound workloads, the bottleneck profile flips. The GPU is still weak, but if the task is not using the GPU heavily, the i9-13900F can perform at a level near its 91st percentile. The CPU’s 3DMark 16-thread score of 9957 and max-thread score of 13985 show significant headroom for parallel processing. The CPU’s single-thread score of 1145 in 3DMark and 4406 in PassMark also show strong lightly threaded performance, so interactive tasks that depend mainly on one core should not be limited by the processor.

There is no measured FPS scaling data for this exact combination, so the bottleneck analysis has to rely on percentile positions and synthetic benchmark scores. The data strongly suggests that the GPU is the primary limiting component for gaming and for any GPU-accelerated graphics workload. The CPU is the primary strength in productivity, development, and compute-heavy tasks that use many threads.

Usage Scenarios

High-refresh gaming: The CPU has enough single-thread performance to drive high frame rates in CPU-bound game logic, but the GPU’s 35th percentile and 4 GB VRAM make it the limiting factor in graphics-heavy scenes. This pairing would require reduced detail settings to keep frame rates high; the CPU is not the bottleneck.

Streaming: The i9-13900F’s 24 cores and 32 threads provide strong multithreaded headroom with a PassMark multithread score of 49693. That gives the CPU room to handle concurrent streaming-related processing while also running a game or other application. The GPU’s low compute score of 2812 means GPU-side compute workloads should be kept modest.

Video editing: CPU-heavy tasks such as timeline processing and export benefit from 40928 in Cinebench R23 multicore and 188022 in PassMark integer math. The GPU’s 4 GB memory and 35th-percentile score limit GPU-accelerated effects and high-resolution previews, so video editing on this system is much stronger on the CPU side.

3D rendering: For CPU rendering, this processor is excellent. The Cinebench R23 multicore score of 40928 places it in the same performance neighborhood as its closest rivals. For GPU rendering, the RX 6400’s 3.565 TFLOPS of FP32 compute and PassMark GPU compute score of 2812 indicate limited throughput. Large GPU-rendered scenes would be constrained by both compute power and 4 GB VRAM.

Software development: Compilation workloads benefit from 24 cores, 32 threads, and a PassMark multithread score of 49693. Integer math performance of 188022 also helps with code transformation and build tasks. The CPU’s single-thread score of 4406 in PassMark supports responsive editor interaction, and the platform supports DDR4 and DDR5 memory, which gives system builders flexibility.

Student and office work: For typical office tasks, the GPU’s PassMark G2D score of 722 is sufficient for 2D desktop work, and the CPU’s single-thread strength makes user interfaces feel responsive. The CPU is far more powerful than office software requires, but that headroom allows heavy multitasking without CPU pressure.

Gaming Performance

The dataset contains no measured FPS values for this exact combination and no per-game entries in the measuredFpsUltraByGame field. Therefore, the figures in this section are estimates based on CPU and GPU benchmark scores. The CPU side is strong for gaming: 3DMark single-thread 1145, 2-thread 2265, and 4-thread 4393 show solid game logic performance. The GPU side is weak: the 35th percentile, PassMark G3D of 7673, and 4 GB VRAM indicate limited graphical throughput.

In GPU-limited games, the RX 6400 will determine playable quality. The 64-bit memory bus and 128.0 GB/s bandwidth are modest, and 4 GB of memory is a practical ceiling for texture-heavy content. The CPU’s high single-thread and multithread scores mean the platform is unlikely to be CPU-limited in most gaming scenarios. Overall, this pairing is best suited to modest graphical settings. The CPU can feed high frame rates, but the GPU will hold back maximum visual quality.

GPU Analysis

The AMD Radeon RX 6400 is a small RDNA 2.0 GPU based on the Navi 24 chip. It is manufactured by TSMC on a 6 nm process with 5,400 million transistors on a 107 mm² die. The GPU has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray accelerators. No tensor core count is listed. Base clock is 1923 MHz, boost clock is 2321 MHz, and game clock is 2039 MHz. The memory subsystem uses 4 GB of GDDR6 on a 64-bit bus, with a memory clock of 2000 MHz and 16 Gbps effective speed. Bandwidth is 128.0 GB/s. The GPU’s fill rates are 74.27 GPixel/s and 111.4 GTexel/s.

Benchmark scores show a GPU that can run modern APIs but does not have high throughput. The Steam Nomad DX12 score of 176 and PassMark DirectX 12 score of 30 indicate weak performance under current-generation graphics loads. PassMark DirectX 11 score of 70 and DirectX 10 score of 54 are also low. The GPU does support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API compatibility is not the problem. The problem is raw performance, which the 35th percentile makes clear.

For rendering, the RX 6400’s 4 GB VRAM creates a hard capacity limit for large scenes and high-resolution textures. The 128.0 GB/s bandwidth limits data movement between memory and the GPU. PassMark GPU compute at 2812 and FP32 throughput of 3.565 TFLOPS show limited compute acceleration. The presence of 12 RT cores allows ray tracing workloads to run in principle, but the overall score profile indicates that ray tracing performance is not a strength of this GPU.

Build Overview

This is a desktop class build that pairs an Intel Core i9-13900F with an AMD Radeon RX 6400. The CPU is a 24-core, 32-thread Raptor Lake-S part with a 65 W TDP. The GPU is a Radeon RX 6000 series part with a 53 W TDP. The combined percentile is 63, which places the overall system in the middle of the desktop pairing distribution. That mid-tier position is misleading, however, because the CPU and GPU are at opposite ends of the spectrum. The CPU is at the 91st percentile, while the GPU is at the 35th percentile.

The overall tier is best described as a CPU-centric desktop build. It is not a balanced gaming machine, but it is a system with substantial CPU compute capacity and a GPU that is adequate for modest graphics workloads. The build’s aggregate score is carried by the processor.

Who Should Build It

Gamers who are willing to lower graphical settings and accept GPU-limited frame rates might consider this pairing, because the CPU’s single-thread score of 4406 in PassMark and 1145 in 3DMark provide strong game logic performance. Content creators with CPU-heavy workflows would benefit from 24 cores, 32 threads, and a Cinebench R23 multicore score of 40928. Software developers working with large codebases gain from a PassMark multithread score of 49693 and integer math score of 188022. Students and general office users would find the CPU more powerful than needed, but the GPU’s G2D score of 722 is enough for 2D desktop tasks. Small businesses building workstations around ECC memory support and a GPU that requires no external power connector could use this pairing for CPU-intensive office and data work, provided graphics requirements stay modest.

Upgrade Path and Platform

The CPU uses Intel Socket 1700. It supports DDR4 and DDR5 memory in a dual-channel configuration, with ECC enabled. The platform provides PCIe Gen 5 with 20 lanes from the CPU, while the RX 6400 itself uses a PCIe 4.0 x4 interface. The CPU’s locked multiplier means overclocking through the multiplier is not an available path.

The GPU has a suggested PSU of 250 W and a TDP of 53 W. The CPU has a TDP of 65 W. Given this power envelope, the current platform is not demanding. The most sensible next upgrade is the GPU. The CPU is already at the 91st percentile and has far more compute capacity than the RX 6400 can use in graphics-bound scenarios. Replacing the RX 6400 with a higher-percentile GPU would address the main bottleneck. The current CPU should not be the first component replaced in most upgrade paths.
