Doom

# CPU Role

The AMD Ryzen 7 9850X3D is an 8-core, 16-thread desktop processor built on the Zen 5 architecture (Granite Ridge codename) using TSMC's 4 nm process. It operates with a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with a 120 W TDP. The processor features a substantial L3 cache of 96 MB (shared), alongside 80 KB of L1 cache per core and 1 MB of L2 cache per core. This cache configuration is particularly relevant for Doom, a fast-paced FPS where frame pacing and consistent delivery of data to the GPU matter more than raw multi-threaded throughput.

In benchmark terms, the CPU sits at the 92nd percentile among all tested processors, with an average benchmark score of 58386. Its nearest rivals in aggregate performance are the Intel Xeon Platinum 8260M (score 58323, deltaPct 0.1%), the Intel Xeon w5-2545 (score 58504, deltaPct -0.2%), the Intel Core i9-14900 (score 58115, deltaPct 0.5%), and the AMD Ryzen AI 9 HX 470 (score 58826, deltaPct -0.7%). The deltas here are remarkably small — all within 0.7% of each other — indicating that the 9850X3D is positioned in a tightly contested performance tier. Single-thread performance, as measured by Cinebench R23 single-core (score 2228), is strong, which aligns well with Doom's engine characteristics that traditionally favor high single-core throughput.

The relationship between CPU and this game's results is indirect but identifiable. At 1080p, where the GPU is less burdened, the CPU's capability to feed frames becomes more visible. The measured FPS at 1080p Low reaches 264 average, which is exceptionally high and suggests the CPU is not a limiting factor even at lower settings. The Ryzen 7's 16 threads and high boost clock provide ample headroom for the game's rendering threads, while the large L3 cache helps with data locality for frequently accessed game assets. At higher resolutions like 4K, the CPU's influence diminishes as the GPU becomes the primary bottleneck — a pattern visible in the measured FPS scaling from 1080p to 2160p.

# FAQ

Q: Does the Ryzen 7 9850X3D bottleneck the RX 7700 XT in Doom at 1080p?

A: No. At 1920x1080 with Low settings, the combo achieves 264 average FPS, and at Medium it reaches 230 average FPS with a minimum of 196 FPS. These figures indicate the CPU provides sufficient headroom to keep the GPU fully utilized at this resolution.

Q: How does the CPU compare to its nearest rivals in aggregate performance?

A: The Ryzen 7 9850X3D has an average benchmark score of 58386, which is 0.1% above the Intel Xeon Platinum 8260M (58323), 0.5% above the Intel Core i9-14900 (58115), 0.2% below the Intel Xeon w5-2545 (58504), and 0.7% below the AMD Ryzen AI 9 HX 470 (58826). All differences are within the margin of typical run-to-run variance.

Q: What is the CPU's percentile ranking among all tested processors?

A: The Ryzen 7 9850X3D is in the 92nd percentile of all CPUs in the benchmark database, meaning it outperforms roughly 92% of tested processors in aggregate benchmark scores.

Q: Is the CPU's 96 MB L3 cache beneficial for Doom specifically?

A: The large shared L3 cache is beneficial for gaming workloads in general, as it reduces latency when accessing frequently used data. In Doom, the measured FPS at 1080p High (194 average) and Ultra (159 average) suggests the cache configuration supports consistent frame delivery, though the data does not isolate cache impact from other CPU attributes.

Q: What is the CPU's memory bandwidth, and does it matter for this game?

A: The CPU supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s. For Doom, this bandwidth is ample, as the game's data footprint and memory access patterns do not typically saturate dual-channel memory bandwidth at the measured FPS levels.

# Settings Recommendations

The measured FPS data provides four settings presets (Low, Medium, High, Ultra) across three resolutions. The optimal choice depends on the target display resolution and refresh rate, but the data supports clear recommendations.

At 1920x1080, all settings deliver high frame rates. Ultra produces 159 average FPS, High produces 194, Medium produces 230 (minimum 196), and Low produces 264. For a 1080p display with a 144 Hz refresh rate, High settings at 194 average FPS provide a comfortable margin above the refresh threshold while maintaining visual quality. Medium at 230 average FPS is also viable for competitive play, but the jump from High to Medium (36 FPS difference) comes at the cost of visual fidelity — the data does not indicate the exact visual difference, but the FPS gain is substantial. Ultra at 159 average FPS still exceeds 144 Hz, making it acceptable for players who prioritize image quality and have a 144 Hz display. Low at 264 average FPS is only recommended for maximum competitive advantage, where every frame counts.

At 2560x1440, High settings produce 126 average FPS, which is above 60 and close to 120 Hz thresholds. Medium produces 149 average FPS (minimum 127), while Ultra produces 103 average FPS and Low produces 171. For 1440p displays with 120 Hz refresh, Medium at 149 average FPS is the sweet spot — it provides a 22% FPS improvement over High while maintaining a minimum of 127 FPS, which stays above 120 Hz. Ultra at 103 average FPS is suitable for 60 Hz displays but will not fully utilize a 120 Hz panel. Low at 171 average FPS is again for competitive scenarios.

At 3840x2160 (4K), High produces 68 average FPS, Medium produces 81 (minimum 69), Ultra produces 56, and Low produces 93. For 4K displays with 60 Hz refresh, Medium at 81 average FPS is the recommended preset — it exceeds 60 FPS with a minimum of 69 FPS, providing a stable experience. High at 68 average FPS is also above 60 but offers less headroom for demanding scenes. Ultra at 56 average FPS dips below 60, which may cause noticeable stutter on a 60 Hz display. Low at 93 average FPS is playable but sacrifices significant visual quality for a 32 FPS gain over Medium.

Across all resolutions, the data indicates that Medium or High settings provide the best balance of frame rate and visual quality, with Medium being the safer choice for maintaining minimum FPS above key thresholds (60 at 4K, 120 at 1440p, and 144 at 1080p).

# How This Combo Ranks

The combination of the AMD Ryzen 7 9850X3D and AMD Radeon RX 7700 XT ranks 1054 out of 2930 tested combos in Doom, placing it in the 64th percentile of all tested combinations. This ranking reflects the GPU's mid-high tier positioning (67th percentile among all GPUs) combined with the CPU's high tier positioning (92nd percentile among all CPUs). The combo rank is lower than the CPU's percentile, which is expected because the GPU is the more limiting component in this pairing for Doom.

The discrepancy between the CPU's high percentile (92) and the combo's mid-tier rank (64th percentile) indicates that the RX 7700 XT holds back the 9850X3D in this game. The data supports this interpretation: at 1080p Low, the combo reaches 264 FPS, but the GPU's raw performance (as measured by Passmark G3D score of 22547) is not in the same tier as the CPU's aggregate benchmark score. The GPU's nearest rivals include the NVIDIA GeForce RTX 5060 Mobile (score 22435, deltaPct 0.5%), the NVIDIA GeForce RTX 4060 Mobile (score 22729, deltaPct -0.8%), the NVIDIA GeForce RTX 2080 (score 22895, deltaPct -1.5%), and the AMD Radeon RX 5700 (score 22170, deltaPct 1.7%). These comparisons place the RX 7700 XT in a competitive but not top-tier segment.

For a player considering this combo, the ranking suggests that Doom performance is solidly mid-pack among all tested systems. The CPU has significant headroom, and upgrading the GPU would yield proportionally larger FPS gains than upgrading the CPU. The combo is well-balanced for 1080p and 1440p gaming, but at 4K, the GPU becomes the clear bottleneck, as evidenced by the FPS scaling discussed in the Resolution Scaling section.

# Resolution Scaling

The measured FPS across resolutions reveals how the system responds to increasing pixel count and what that says about the limiting component. At High settings, the average FPS progression is 194 at 1080p, 126 at 1440p, and 68 at 4K. The drop from 1080p to 1440p is 68 FPS (35% reduction), while the drop from 1440p to 4K is 58 FPS (46% reduction). The total drop from 1080p to 4K is 126 FPS (65% reduction). At Low settings, the progression is 264 at 1080p, 171 at 1440p, and 93 at 4K — a drop of 93 FPS (35%) from 1080p to 1440p, then 78 FPS (46%) from 1440p to 4K, totaling 171 FPS (65%) from 1080p to 4K.

The consistent percentage drops (35% from 1080p to 1440p, 46% from 1440p to 4K, and 65% overall) across both Low and High settings indicate that the GPU is the primary scaling factor. If the CPU were the bottleneck, the FPS would not scale proportionally with resolution — at Low settings, a CPU-limited system would show flat FPS across resolutions. Here, even at Low settings, the FPS drops by 65% from 1080p to 4K, which is nearly exactly the pixel count increase (1080p has 2,073,600 pixels; 4K has 8,294,400 pixels — exactly 4x, but the FPS drop is 65%, not 75%). The non-linear relationship (65% drop for a 300% increase in pixels) suggests that while the GPU is the dominant limiter, there is some CPU or memory contribution at lower resolutions that becomes less relevant at 4K.

At Ultra settings, the progression is 159 at 1080p, 103 at 1440p, and 56 at 4K — a 35% drop from 1080p to 1440p, a 46% drop from 1440p to 4K, and a 65% overall drop. The identical percentage scaling across all three settings presets is a strong indicator that the GPU's pixel throughput is the limiting factor at all resolutions. The Ryzen 7 9850X3D's high single-thread performance (Cinebench R23 single-core score 2228) ensures that the CPU does not become a bottleneck even at 1080p Low where the game is rendering at the highest frame rates.

The medium settings data includes minimum FPS values, which further illustrate the scaling: at 1080p Medium, the minimum is 196 FPS; at 1440p Medium, the minimum is 127 FPS; at 4K Medium, the minimum is 69 FPS. The minimum FPS follows a similar percentage trend (35% drop from 1080p to 1440p, 46% from 1440p to 4K), confirming that frame delivery scales consistently with resolution.

# Measured FPS Breakdown

At 1920x1080, the measured average FPS by settings preset is as follows: Low produces 264 average FPS, Medium produces 230 average FPS with a minimum of 196 and maximum of 265, High produces 194 average FPS, and Ultra produces 159 average FPS. The spread from Low to Ultra is 105 FPS, representing a 40% reduction from Low to Ultra. The Medium preset shows a narrow min-max range (196 to 265), indicating consistent frame delivery.

At 2560x1440, the measured average FPS is: Low 171, Medium 149 (minimum 127, maximum 171), High 126, and Ultra 103. The spread from Low to Ultra is 68 FPS, a 40% reduction — identical to the 1080p percentage spread. The Medium min-max range (127 to 171) is proportionally similar to 1080p, showing that frame consistency scales with resolution.

At 3840x2160, the measured average FPS is: Low 93, Medium 81 (minimum 69, maximum 93), High 68, and Ultra 56. The spread from Low to Ultra is 37 FPS, again a 40% reduction. The Medium min-max range (69 to 93) maintains the same proportional consistency as lower resolutions.

The pattern across all resolutions is remarkably consistent: each settings tier reduces FPS by approximately 16-18% (Low to Medium), 15-16% (Medium to High), and 18-19% (High to Ultra). For example, at 1080p, the reduction from Low to Medium is 34 FPS (13%), Medium to High is 36 FPS (16%), and High to Ultra is 35 FPS (18%). At 4K, the reductions are 12 FPS (13%), 13 FPS (16%), and 12 FPS (18%) respectively. This consistency indicates that the settings presets scale uniformly, with each tier imposing a similar relative cost on the GPU regardless of resolution.

The minimum FPS data points (only available for Medium settings) show that the worst-case frame delivery stays within 15% of the average: at 1080p, the minimum is 196 vs. average 230 (15% below); at 1440p, minimum 127 vs. average 149 (15% below); at 4K, minimum 69 vs. average 81 (15% below). This consistency suggests the game's frame pacing is stable across resolutions when using Medium settings.

# GPU Role

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture (Navi 32 chip, codename "Wheat Nas") using TSMC's 5 nm process. It has 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of memory bandwidth. The GPU clocks are: base 1435 MHz, boost 2544 MHz, and game clock 2171 MHz. Memory operates at 2250 MHz with 18 Gbps effective speed. The GPU has 3456 shading units, 216 texture mapping units, and 96 render output units, along with 54 ray tracing cores. Its FP32 performance is 35.17 TFLOPS, with a pixel rate of 244.2 GPixel/s and texture rate of 549.5 GTexel/s. The TDP is 245 W, requiring a 550 W suggested PSU and dual 8-pin power connectors.

In the benchmark database, the RX 7700 XT ranks in the 67th percentile among all GPUs, with an average benchmark score of 22549. Its nearest rivals in aggregate score are the NVIDIA GeForce RTX 5060 Mobile (score 22435, deltaPct 0.5%), the NVIDIA GeForce RTX 4060 Mobile (score 22729, deltaPct -0.8%), the NVIDIA GeForce RTX 2080 (score 22895, deltaPct -1.5%), and the AMD Radeon RX 5700 (score 22170, deltaPct 1.7%). These deltas are small, placing the GPU in a tightly contested mid-to-high tier.

In Doom, the GPU's role is defined by its pixel throughput and memory bandwidth. At 4K Ultra, the combo produces 56 average FPS, which is below the 60 FPS target for smooth gameplay. At 4K High, it achieves 68 average FPS, just above 60. The GPU's 12 GB VRAM is sufficient for Doom at all settings and resolutions tested, as the game's texture requirements at 4K Ultra do not appear to cause memory-related stuttering — the minimum FPS values for Medium at 4K (69) remain proportional to the average.

The GPU's memory bandwidth of 432.0 GB/s is a relevant factor at 4K, where the game must move more texture and geometry data. The measured FPS at 4K Medium (81 average) versus 4K Low (93 average) shows a 12 FPS difference, indicating that the GPU's shading units and memory subsystem are both engaged. The GPU's boost clock of 2544 MHz and game clock of 2171 MHz provide the computational throughput for the measured FPS levels, while the 12 GB VRAM ensures no capacity-related degradation at the tested settings.

Compared to its nearest rivals, the RX 7700 XT's performance in Doom is consistent with its aggregate benchmark positioning. The GPU's 67th percentile ranking aligns with the combo's 64th percentile ranking in Doom, suggesting that the GPU is the primary determinant of the combo's performance in this game. The CPU's high percentile (92) does not boost the combo's rank because Doom's frame rates at the tested resolutions are largely GPU-bound, as evidenced by the consistent 65% FPS drop from 1080p to 4K across all settings.
