Doom

Resolution Scaling

The measured FPS data for this AMD Ryzen 5 5600GT + NVIDIA GeForce RTX 5070 combination in Doom reveals a classic pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo delivers 335 FPS, but dropping to 1440p Low reduces that to 217 FPS, a 35% performance decrease. Moving to 4K Low further drops the frame rate to 118 FPS, which represents a 65% reduction from the 1080p figure. This steep decline across resolutions indicates the rendering workload is scaling heavily with pixel count, which points to the GPU as the primary limiting component at higher resolutions.

The scaling behavior is consistent across all settings presets. At High settings, the combo produces 247 FPS at 1080p, 160 FPS at 1440p, and 87 FPS at 4K. The percentage drops from 1080p to 1440p are roughly 35% for Low, High, and Medium presets, while the 4K step adds another 30-35% reduction on top of that. For Ultra settings, the pattern holds: 202 FPS at 1080p, 131 FPS at 1440p, and 71 FPS at 4K. These consistent scaling ratios suggest the frame rate is being driven by the GPU's fill rate and shading capacity rather than any CPU-side bottleneck.

Notably, the frame time consistency also degrades with resolution. At 1080p Medium, the recorded range spans 248 to 336 FPS, a spread of 88 FPS. At 1440p Medium, that range narrows to 161–217 FPS, a 56 FPS spread. At 4K Medium, the range is 87–118 FPS, just 31 FPS apart. This tightening of the frame rate distribution at higher resolutions indicates the GPU is becoming more consistently saturated, reducing the variability that comes from CPU-driven frame pacing at lower resolutions. The data shows that at 1080p, the CPU can occasionally feed frames faster than the GPU can process them, creating wider swings, whereas at 4K, the GPU is uniformly the bottleneck.

The fact that 4K Ultra still manages 71 FPS average while 4K Low reaches 118 FPS shows that even at the most demanding settings, this combination remains fully playable. The scaling from Ultra to Low at 4K (71 to 118 FPS) is a 66% uplift, which is substantial but not enough to push past the 120 FPS threshold at 4K. This indicates that the RTX 5070's rendering resources are the limiting factor at this resolution, and the CPU's role diminishes as pixel count rises.

How This Combo Ranks

Within the benchmark database's tested combinations for Doom, this specific pairing of AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 5070 achieves a combo rank of 754 out of 3,712 total tested combos. This places the system in the top 20% of all configurations evaluated in this game, which is a strong showing given the breadth of hardware combinations tracked. The percentile positioning reflects that most tested systems deliver lower average frame rates across the resolution and settings matrix.

The combo rank of 754 is particularly impressive when considering the CPU's overall standing. The Ryzen 5 5600GT sits at the 74th percentile among all CPUs in the database, with an average benchmark score of 20,733. Its nearest rivals include the Intel Core i5-12490F, which scores 20,802 (a 0.3% delta), the Intel Xeon 6325P at 20,821 (0.4% delta), and the Intel Core Ultra 5 125U at 20,826 (0.4% delta). The fact that this mid-range CPU can pair with a high-end GPU to reach the 754th spot out of 3,712 combos suggests the system is well-balanced for Doom's engine, which is known for being less CPU-intensive than many modern titles.

The GPU's contribution to this rank is more substantial. The RTX 5070 sits at the 82nd percentile among all GPUs, with an average benchmark score of 40,377. Its nearest rivals in the database are the AMD Radeon Pro 580 (score 40,318, delta 0.1%), AMD Radeon Pro WX 7100 (score 40,063, delta 0.8%), and AMD Radeon Pro 5300 (score 40,870, delta -1.2%). While the GPU's percentile is higher than the CPU's, the combo's rank in Doom specifically benefits from the game's Vulkan API implementation, which can leverage the CPU's 6 cores and 12 threads effectively.

Compared to other combos in the database, this system's 4K Ultra average of 71 FPS and 1080p Ultra average of 202 FPS are strong indicators of why it ranks in the top quintile. Many tested combinations with lower-tier GPUs or older CPUs will struggle to maintain 60 FPS at 4K Ultra in this title, whereas this pairing exceeds that threshold comfortably. The rank also reflects the consistency across resolutions — there is no resolution or settings preset where the combo falls below 71 FPS, which is a key differentiator versus less capable systems.

CPU Role

The AMD Ryzen 5 5600GT brings 6 cores and 12 threads to this pairing, based on the Zen 3 architecture (codenamed Cezanne) fabricated on a 7 nm TSMC process. The CPU runs at a base clock of 3.60 GHz with a boost clock of 4.60 GHz, and its 65 W TDP classifies it as an efficient desktop processor. The cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and a 16 MB L3 cache, which is shared across all cores. Memory support is DDR4 with dual-channel configuration, providing 51.2 GB/s of bandwidth.

In Doom, the CPU's role is most evident at lower resolutions where frame rates are highest. At 1080p Low, the combo produces 335 FPS, which is a demanding scenario for any processor to feed the GPU. The 12 threads allow the game's render thread and worker threads to distribute load effectively, preventing CPU-side stalls that would otherwise cap frame rates. The single-thread performance, evidenced by a 3DMark single-thread score of 913 and Cinebench R23 single-core score of 2,438, is adequate for the game's main thread, which handles draw calls and game logic.

The boost clock of 4.60 GHz is particularly relevant for Doom's engine, which has been optimized to scale well with higher IPC and clock speeds. The Zen 3 architecture delivers strong instructions-per-clock, and the 4.60 GHz boost ensures that the CPU can keep up with the GPU's demand for frames at 1080p. The multi-threaded capabilities are reflected in Cinebench R23 multi-core score of 17,272 and Geekbench multi-core score of 7,986, which indicate that the CPU can handle the game's background tasks without bottlenecking.

At 4K resolutions, the CPU's influence diminishes significantly. The frame rates at 4K (71–118 FPS across settings) are well within the CPU's capability to feed, and the bottleneck shifts almost entirely to the GPU. The data confirms this: the percentage drop from 1440p to 4K is consistent across all settings, regardless of how demanding the CPU's workload might be at lower resolutions. The CPU's 16 MB L3 cache is sufficient for the game's working set, and the 51.2 GB/s memory bandwidth does not appear to constrain performance in this title. Overall, the Ryzen 5 5600GT provides a capable foundation that does not hold back the RTX 5070 at any resolution.

Measured FPS Breakdown

At 1080p, the combo delivers its highest frame rates across all settings. Low settings produce an average of 335 FPS, Medium drops to 292 FPS, High settles at 247 FPS, and Ultra reduces to 202 FPS. The Medium preset shows a measured range of 248 to 336 FPS, indicating the system can occasionally hit very high frame rates even at medium fidelity. The difference between Low and Ultra at 1080p is 133 FPS, a 40% reduction, which demonstrates the significant cost of enabling Ultra-quality effects on the GPU.

Moving to 1440p, the frame rates remain high but show the expected reduction. Low settings average 217 FPS, Medium averages 189 FPS (with a range of 161–217 FPS), High averages 160 FPS, and Ultra averages 131 FPS. The gap between Low and Ultra at 1440p is 86 FPS, which is a 40% reduction — nearly identical to the scaling seen at 1080p. This consistency suggests the game's settings scale linearly with resolution, and the GPU is being utilized efficiently across the board.

At 4K, the performance remains playable but drops significantly. Low settings average 118 FPS, Medium averages 102 FPS (range 87–118 FPS), High averages 87 FPS, and Ultra averages 71 FPS. The Low-to-Ultra gap at 4K is 47 FPS, again a 40% reduction. Notably, the 4K Medium range of 87–118 FPS overlaps with the 4K High average of 87 FPS, indicating that at these resolutions, the settings presets have less impact on minimum frame rates than they do at lower resolutions.

The most striking data point is the 1080p Low result of 335 FPS, which places this combo in elite territory for high-refresh-rate gaming. Even at 1440p High, the 160 FPS average exceeds the refresh rate of most 1440p monitors. At 4K, the Ultra preset's 71 FPS average is above the 60 FPS threshold for smooth gameplay, while 4K Low's 118 FPS approaches high-refresh-rate 4K territory. The min/max data for Medium presets at all three resolutions shows that the system maintains a consistent frame rate without major dips.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture using a 5 nm TSMC process, with the GB205 chip containing 31,100 million transistors on a 263 mm² die. The GPU operates with a base clock of 2325 MHz and a boost clock of 2512 MHz, paired with 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of memory bandwidth. The memory runs at 1750 MHz (28 Gbps effective), and the GPU includes 6,144 shading units, 192 TMUs, and 80 ROPs.

In Doom, the GPU's 12 GB VRAM is more than sufficient for the game's requirements, even at 4K Ultra. The game's textures and geometry fit comfortably within the memory capacity, and the 672.0 GB/s bandwidth ensures that texture streaming and buffer updates do not create bottlenecks. The 48 RT cores and 192 tensor cores are present but are not heavily utilized in this title, which has no ray tracing features. The GPU's raw rasterization performance, measured at 30.87 TFLOPS FP32, is what drives the high frame rates observed.

The boost clock of 2512 MHz is a key factor in the GPU's performance, as Doom's engine responds well to higher clock speeds. The 201.0 GPixel/s pixel rate and 482.3 GTexel/s texture rate provide the fill rate needed to sustain the measured frame rates, particularly at 4K where pixel throughput becomes critical. The 80 ROPs handle the final pixel output, and the data suggests they are not a limiting factor — the consistent scaling from 1080p to 4K indicates the GPU is being used efficiently.

The RTX 5070's overall standing in the database, at the 82nd percentile among all GPUs, is reflected in its Doom performance. The GPU's nearest rivals in synthetic benchmarks — the AMD Radeon Pro 580, Radeon Pro WX 7100, and Radeon Pro 5300 — all score within 2% of the RTX 5070's average benchmark score, but the RTX 5070's architecture provides superior real-world gaming performance in this title. The GPU's PCIe 5.0 x16 interface ensures no bandwidth limitations with the CPU's PCIe Gen 3 connection, and the 250 W TDP is a reasonable power envelope for the performance delivered.
