Doom

The AMD Ryzen 5 7500F paired with the AMD Radeon RX 7900 XTX delivers a formidable 1080p experience in Doom, but the data reveals a clear shift in bottleneck behavior as resolution climbs. This combination is ranked 232nd out of 1681 tested combos, placing it in the top 14% of all systems evaluated for this title. The measured FPS numbers show a system that is heavily GPU-bound at 4K, yet still capable of pushing past 360 FPS at 1080p with lowered settings.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, indicating that the RX 7900 XTX becomes the limiting factor at higher resolutions. At Low settings, the average frame rate falls from 363.6 FPS at 1080p to 234.8 FPS at 1440p, then to 129.1 FPS at 4K. That represents a 45% reduction from 1080p to 1440p, and a further 45% reduction from 1440p to 4K. The scaling is nearly linear with pixel count, which is the signature of a GPU-bound scenario.

At Ultra settings, the pattern is similar but with lower absolute numbers. The system delivers 220.3 FPS at 1080p, 144.6 FPS at 1440p, and 74.7 FPS at 4K. The 4K result is less than half of the 1080p result, showing that the most demanding preset amplifies the GPU load disproportionately. The gap between High and Ultra at 4K is particularly notable — 94.6 FPS versus 74.7 FPS — suggesting that Ultra settings include effects that are especially punishing on the RDNA 3.0 architecture.

The data indicates that this combo is not CPU-limited at any resolution tested. The 1080p Low result of 363.6 FPS is extraordinarily high, and the fact that the CPU can feed the GPU at that rate without creating a plateau suggests the Ryzen 5 7500F has ample headroom. If the CPU were the bottleneck, we would expect to see smaller FPS differences between resolutions, but the consistent 45% scaling rule disproves that theory.

GPU Role

The RX 7900 XTX is the dominant component in this pairing, and its specifications explain the 4K performance profile. With 24 GB of GDDR6 memory on a 384-bit bus, the card delivers 960.0 GB/s of bandwidth, which is more than sufficient for Doom's texture-heavy environments at any resolution. The memory clock runs at 2500 MHz (20 Gbps effective), and the boost clock reaches 2498 MHz, with a game clock of 2365 MHz.

The GPU's compute resources are substantial: 6144 shading units, 384 TMUs, and 192 ROPs. The pixel rate of 479.6 GPixel/s and texture rate of 959.2 GTexel/s are high enough that even at 4K Ultra, the card is only producing 74.7 FPS, which means it is nowhere near fill-rate limited. The 61.39 TFLOPS FP32 throughput is the more likely constraint, as Doom's lighting and post-processing effects at Ultra settings scale with shader complexity.

The 355 W TDP and 750 W suggested PSU indicate this is a power-hungry card, but that is expected for a flagship. The 24 GB frame buffer is overkill for Doom — the game was released in 2016 and does not require more than 8 GB even at 4K Ultra — but the headroom ensures zero risk of VRAM-related stuttering. The GPU's benchmark scores reinforce its position: it holds the 85th percentile among all GPUs, with an average benchmark score of 44019.

How This Combo Ranks

The combo rank of 232 out of 1681 places this system in the 86th percentile of all tested combinations for Doom. That is a strong result, but not a top-tier one, which is surprising given the caliber of the GPU. The explanation lies in the CPU pairing: the Ryzen 5 7500F is a 6-core, 12-thread processor that, while capable, does not have the raw multi-threaded throughput of higher-end Ryzen 9 or Intel Core i9 parts.

The CPU's nearest rivals in average benchmark score include the Intel Core i7-11850H (deltaPct 0.1), AMD Ryzen 7 2700X (deltaPct -0.3), AMD Ryzen 5 8400F (deltaPct -0.3), and AMD Ryzen 9 6900HX (deltaPct 0.4). These are all within 0.4% of the 7500F's average score of 24993, meaning the CPU is firmly in the mid-range tier. The GPU's nearest rivals — the AMD Radeon Pro 580 (deltaPct -0.4), NVIDIA GeForce RTX 4090 Mobile (deltaPct 0.8), NVIDIA Quadro M6000 (deltaPct 1.6), and NVIDIA GeForce RTX 4070 Ti (deltaPct -2) — show that the 7900 XTX is slightly above average among high-end cards, but not a clear leader.

The rank of 232 suggests that many combos with faster CPUs achieve higher FPS in Doom, particularly at 1080p where the CPU's single-thread performance becomes more relevant. The 7500F's single-thread score of 974 in 3DMark and 3218 in Cinebench R23 are decent, but they are not class-leading.

Measured FPS Breakdown

The measured data covers three resolutions and four settings levels, providing a complete picture of performance. At 1080p Low, the system hits 363.6 FPS average, which is the highest result in the entire dataset. Moving to Medium drops that to 317.6 FPS, High to 270.7 FPS, and Ultra to 220.3 FPS. The step from Low to Medium is a 13% reduction, while High to Ultra is a 19% reduction.

At 1440p, the numbers scale down proportionally. Low delivers 234.8 FPS, Medium 202.5 FPS, High 176.2 FPS, and Ultra 144.6 FPS. The relative gaps between settings are similar to 1080p, confirming that the GPU is the limiting factor across the board. The 1440p Ultra result of 144.6 FPS is still well above the 144 Hz refresh rate that many monitors use, making this combo a strong choice for high-refresh 1440p gaming.

At 4K, the results are more varied. Low produces 129.1 FPS, Medium 113.8 FPS, High 94.6 FPS, and Ultra 74.7 FPS. The gap between Medium and High is 17%, while the gap between High and Ultra is 21%. This indicates that Ultra settings at 4K are particularly demanding, likely due to increased shadow quality and ambient occlusion effects. For a 60 Hz 4K display, even Ultra settings are playable, but for 120 Hz panels, players will need to drop to High or Medium.

FAQ

Q: Can this combo run Doom at 4K 120 FPS?

A: No. The highest 4K result is 129.1 FPS at Low settings, but High drops to 94.6 FPS and Ultra to 74.7 FPS. To hit 120 FPS at 4K, players must use Low settings, which defeats the purpose of 4K.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: The data shows the GPU is the limiting factor even at 1080p. The FPS scales consistently with resolution changes, and the CPU's single-thread performance (974 in 3DMark single-thread) is sufficient to saturate the GPU's output.

Q: What is the best setting for 1440p gaming?

A: Ultra settings at 1440p deliver 144.6 FPS, which is ideal for 144 Hz monitors. If the display is 165 Hz or higher, dropping to High (176.2 FPS) or Medium (202.5 FPS) will provide more headroom.

Q: How does the RX 7900 XTX compare to its nearest rival, the RTX 4070 Ti?

A: The RX 7900 XTX has an average benchmark score of 44019, which is 2% higher than the RTX 4070 Ti's score. However, the RTX 4090 Mobile is 0.8% faster, showing that the 7900 XTX is competitive but not dominant.

Q: Is the Ryzen 5 7500F a good match for the RX 7900 XTX in this game?

A: The combo ranks 232nd out of 1681, which is strong but not optimal. The CPU's average benchmark score of 24993 is within 0.4% of several rivals, and its multi-thread performance (22799 in Cinebench R23) is sufficient for Doom, which is not heavily threaded.

Q: What is the FPS difference between Low and Ultra at 1080p?

A: Low delivers 363.6 FPS, while Ultra delivers 220.3 FPS. That is a 143.3 FPS difference, or approximately 39% lower performance at Ultra compared to Low.

CPU Role

The Ryzen 5 7500F is a 6-core, 12-thread processor based on Zen 4 architecture, built on a 5 nm process by TSMC. It has a base clock of 3.70 GHz and a boost clock of 5.00 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. Memory support is DDR5 with dual-channel configuration, providing 83.2 GB/s of bandwidth.

In Doom, the CPU's role is secondary to the GPU, but its single-thread performance matters at high frame rates. The 3DMark single-thread score of 974 and Cinebench R23 single-core score of 3218 are respectable, but not exceptional for a modern desktop CPU. The multi-thread scores are stronger: Cinebench R23 multi-core hits 22799, and Geekbench multi-core reaches 12686.

The CPU's percentile rank of 82 among all CPUs indicates it is better than 82% of tested processors. Its average benchmark score of 24993 is nearly identical to the Intel Core i7-11850H (24974, deltaPct 0.1) and AMD Ryzen 9 6900HX (24897, deltaPct 0.4). The AMD Ryzen 7 2700X and Ryzen 5 8400F are marginally faster at 25057 and 25064 respectively, but the differences are negligible.

For Doom specifically, the CPU's performance is sufficient to avoid bottlenecking the RX 7900 XTX at any resolution. The 1080p Low result of 363.6 FPS reflects the CPU's ability to feed frames quickly. However, the combo rank of 232 suggests that pairing the 7900 XTX with a faster CPU (such as a Ryzen 7 or 9) would yield higher FPS, particularly at 1080p where CPU overhead is more pronounced. The 7500F's 6 cores and 12 threads are adequate for Doom, which is not a heavily multi-threaded game, but the lower single-thread score compared to higher-tier CPUs means the GPU cannot always reach its full potential.
