Doom

Resolution Scaling

The measured frame rates for this AMD Ryzen 7 5700X and Radeon RX 7900 XTX combination in Doom reveal a clear scaling pattern as resolution climbs. At 1920x1080 with Low settings, the combo delivers 355.9 FPS on average. Moving to 2560x1440 Low drops that to 233.4 FPS, a reduction of roughly one-third. At 3840x2160 Low, the average falls further to 125.9 FPS. The transition from 1440p to 4K costs nearly half the frame rate, which is a substantial hit even for a high-end GPU.

The scaling story is similar across other settings tiers. At High settings, the frame rate goes from 268 FPS at 1080p to 175.3 FPS at 1440p, then down to 96.2 FPS at 4K. The drop from 1080p to 1440p is about 35 percent, while the drop from 1440p to 4K is about 45 percent. This indicates that the GPU is becoming the primary limiting factor at higher resolutions, as the rendering load increases disproportionately with pixel count.

At Ultra settings, the pattern is even more pronounced. The combo manages 217.1 FPS at 1080p, 145 FPS at 1440p, and 79.6 FPS at 4K. The 4K figure is less than half of the 1080p result, showing that the most demanding preset pushes the GPU hard. The data suggests that at 1080p, the CPU still has headroom to feed the GPU, but by 4K, the Radeon RX 7900 XTX is fully saturated. The gap between Low and Ultra at 1080p is 138.8 FPS, while at 4K that gap narrows to 46.3 FPS, reinforcing that resolution scaling compresses the performance difference between settings as the GPU becomes the bottleneck.

How This Combo Ranks

In the benchmark database, this specific CPU-GPU pairing ranks 251 out of 1681 tested combinations for Doom. That places it in the top 15 percent of all combos tested in this game, which is a strong showing for a mid-range CPU paired with a flagship GPU. The rank reflects the overall measured performance across all resolutions and settings, and the data shows that the combo consistently delivers high frame rates even at 4K Ultra.

The Ryzen 7 5700X itself holds an 83rd percentile ranking among all CPUs in the database, with an average benchmark score of 26214. Its nearest rivals in the CPU benchmarks include the Intel Core i9-11900KF, which scores 26196 with a delta of 0.1 percent, and the AMD Ryzen 5 7600X, which scores 26272 with a delta of -0.2 percent. This places the 5700X in a tight cluster where performance differences are within a fraction of a percent. The Ryzen 7 PRO 6850U and Ryzen 5 5500GT also sit within 0.2 percent, meaning the 5700X is effectively tied with several other processors in raw compute benchmarks.

The GPU, meanwhile, ranks at the 85th percentile among all GPUs, with an average benchmark score of 44019. Its closest rivals include the NVIDIA GeForce RTX 4070 Ti, which scores 44900 with a delta of -2 percent, and the AMD Radeon Pro 580 at 44195 with a delta of -0.4 percent. The RTX 4090 Mobile scores 43667 with a delta of 0.8 percent, while the Quadro M6000 scores 43313 with a delta of 1.6 percent. The RX 7900 XTX sits slightly below the RTX 4070 Ti in synthetic scores, yet in Doom, the measured FPS indicates this combo is well above average. The combination rank of 251 out of 1681 suggests that the pairing works particularly well in this title, likely due to the GPU's raw throughput and the CPU's sufficient single-thread performance.

GPU Role

The Radeon RX 7900 XTX is built on the RDNA 3.0 architecture with a Navi 31 chip, fabricated on a 5 nm process at TSMC. It packs 57,700 million transistors across a 529 mm² die. The GPU operates with a base clock of 1929 MHz, a game clock of 2365 MHz, and a boost clock of 2498 MHz. Memory runs at 2500 MHz with 20 Gbps effective speed. The card features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. This memory configuration is critical for Doom at 4K, where high-resolution textures and large frame buffers demand substantial bandwidth.

The GPU's compute resources include 6144 shading units, 384 texture mapping units, and 192 raster output units. It also has 96 ray tracing cores, though Doom's original release does not heavily utilize ray tracing. The pixel rate is 479.6 GPixel/s, and the texture rate is 959.2 GTexel/s. Floating-point performance is rated at 61.39 TFLOPS for FP32 and 122.8 TFLOPS for FP16. These figures translate directly into the measured frame rates: at 4K Ultra, the combo still manages 79.6 FPS, which is playable but not silky smooth. The fact that Low settings at 4K produce 125.9 FPS shows that the GPU has ample headroom when pixel shading demands are reduced.

In the GPU benchmark suite, the RX 7900 XTX scores 31238 in Passmark G3D and 17689 in Passmark GPU Compute. Its Geekbench OpenCL score is 189573, and Vulkan score is 192597. These synthetic results align with the high FPS observed in Doom, particularly at 1440p where the GPU can stretch its legs. The card's 24 GB memory buffer is more than sufficient for Doom, even at 4K Ultra, which likely prevents any memory-related stuttering or frame drops in the measured data.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptionally high frame rates across all settings. Low settings yield 355.9 FPS, Medium produces 316.1 FPS, High achieves 268 FPS, and Ultra drops to 217.1 FPS. The spread from Low to Ultra is 138.8 FPS, indicating that the GPU is not the bottleneck at this resolution; instead, the CPU's single-thread performance and memory bandwidth are likely the limiting factors. The Ryzen 7 5700X's boost clock of 4.60 GHz and 32 MB of shared L3 cache contribute to maintaining high frame rates even at these extreme levels.

Moving to 2560x1440, the frame rates remain high but show a more significant impact from resolution scaling. Low settings average 233.4 FPS, Medium 207.7 FPS, High 175.3 FPS, and Ultra 145 FPS. The gap between Low and Ultra is 88.4 FPS, narrower than at 1080p. This suggests that the GPU is starting to become more involved, but still has enough headroom to handle the increased pixel count without major performance degradation. The 1440p results are all well above 144 Hz refresh rates, making this combo ideal for high-refresh-rate monitors at this resolution.

At 3840x2160, the performance drops are more pronounced. Low settings produce 125.9 FPS, Medium 110.8 FPS, High 96.2 FPS, and Ultra 79.6 FPS. The spread from Low to Ultra is 46.3 FPS, much tighter than at lower resolutions. This indicates that the GPU is now the primary bottleneck, as the rendering load at 4K taxes the RX 7900 XTX's compute and memory resources. Even at Ultra settings, the combo maintains nearly 80 FPS, which is respectable for a demanding title at 4K. The data shows that for competitive play, dropping to Medium or Low at 4K can push frame rates above 110 FPS, providing a smooth experience on high-refresh displays.

CPU Role

The AMD Ryzen 7 5700X is a Zen 3 architecture processor with 8 cores and 16 threads, based on the Vermeer codename. It has a base clock of 3.40 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The CPU supports DDR4 memory with dual-channel configuration and a memory bandwidth of 51.2 GB/s. It features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache. The processor is manufactured on a 7 nm process at TSMC, with 4,150 million transistors on a 74 mm² die.

In Doom, the CPU's role is most evident at 1080p, where frame rates exceed 300 FPS on Low settings. At these high frame rates, the CPU must feed the GPU with draw calls and game logic updates quickly enough to avoid bottlenecking. The 5700X's single-thread performance, as measured by a 3DMark single-thread score of 921 and Cinebench R23 single-core score of 3193, is sufficient to keep up with the RX 7900 XTX at 1080p. The multi-threaded performance, with a Cinebench R23 multi-core score of 22620 and a Geekbench multi-core score of 9720, also helps in maintaining consistent frame times across all settings.

The CPU's benchmark scores place it in a tight competitive cluster. Its average benchmark score of 26214 is nearly identical to the Intel Core i9-11900KF at 26196 (delta 0.1 percent) and the AMD Ryzen 5 7600X at 26272 (delta -0.2 percent). This means that in synthetic tests, the 5700X is functionally equivalent to several other CPUs, but in Doom, the combination with the RX 7900 XTX yields a rank of 251 out of 1681, which is better than many combos featuring newer or more expensive processors. The CPU's 83rd percentile ranking among all CPUs confirms that it is a solid performer, though not at the absolute top tier. The data indicates that for Doom specifically, the 5700X provides enough processing power to avoid limiting the GPU at 1440p and below, while at 4K, the GPU becomes the clear bottleneck, allowing the CPU to operate with plenty of headroom.
