Doom

The data shows the AMD Ryzen 5 7500X3D and NVIDIA GeForce RTX 3080 combination delivers a highly playable experience in Doom across all tested resolutions and settings. The measured frame rates indicate a system that scales predictably with graphical load, with the CPU providing ample headroom for the GPU to flex its muscle at higher resolutions. The following analysis breaks down the performance characteristics of this pairing.

Resolution Scaling

The performance scaling from 1080p to 4K clearly illustrates the transition from a CPU-bound scenario to a GPU-bound one. At 1920x1080 with Low settings, the system achieves an average of 301 FPS. Moving to 2560x1440 at Low settings, the average drops to 195 FPS, a reduction of approximately 35%. At 3840x2160 with Low settings, the average further declines to 105 FPS, another 46% drop from the 1440p figure.

This scaling pattern is classic for a high-refresh-rate title. At 1080p, the frame rate is so high that the CPU's ability to feed draw calls becomes the limiting factor, preventing the GPU from running at full capacity. The 301 FPS average at 1080p Low is a hard ceiling for this processor in this scenario. As resolution increases, the GPU takes over as the primary bottleneck, and the FPS begins to scale more directly with the pixel count and rendering load.

The delta between Low and Ultra settings at each resolution further confirms this dynamic. At 1080p, the gap between Low (301 FPS) and Ultra (181 FPS) is 120 FPS, or a 40% performance penalty for maxing out the settings. At 4K, the same comparison shows a gap of 42 FPS between Low (105 FPS) and Ultra (63 FPS), a 40% penalty. The percentage penalty is consistent, but the absolute FPS cost is much higher at lower resolutions where the CPU is keeping the GPU well-fed.

The data suggests that for a 144Hz monitor, 2560x1440 is the sweet spot for this combination. At Medium settings, the system maintains an average of 170 FPS with a minimum of 144 FPS, which is right at the threshold for a smooth, tear-free experience on a standard 144Hz display. At 4K, the system is capable of 4K 60 FPS+ gaming at High and Medium settings, with averages of 78 and 92 FPS respectively, but the Ultra preset dips to an average of 63 FPS, which is less comfortable for high-refresh displays.

CPU Role

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, based on the Raphael codename and Zen 4 architecture. It operates on a 5 nm process from TSMC, featuring a base clock of 4.00 GHz and a boost clock of 4.50 GHz. Its defining feature is a large 96 MB shared L3 cache, which is a significant asset for gaming workloads that often rely on fast access to frequently used data.

The CPU's performance in synthetic benchmarks shows a strong all-around profile. It scores 25047 in Passmark's multithread test and 3494 in the single-thread test. These scores place it in the 89th percentile of all CPUs, indicating that it is a high-performing part. Its nearest rivals, such as the Intel Core i9-13950HX and Intel Core i5-14600, have average scores within 0.7% of the Ryzen 5, showing that it trades blows with top-tier mobile and desktop chips from the competition.

For Doom, the CPU's role is to ensure a consistent, high frame rate. The 301 FPS average at 1080p Low is the primary evidence that the CPU is not a bottleneck in this game. The 6 cores and 12 threads are more than sufficient for the game's engine, and the high boost clock of 4.50 GHz helps maintain high minimum frame rates. The large L3 cache likely contributes to the consistency of the frame pacing, ensuring that the GPU is never starved of data.

The Passmark physics score of 2779 is indicative of the CPU's ability to handle complex in-game calculations. In a fast-paced FPS like Doom, this translates to stable performance during chaotic combat scenes with many enemies and effects on screen. The data shows that the CPU is a capable partner for the RTX 3080, providing enough headroom to push high frame rates at 1440p and to maintain playable 60+ FPS at 4K without being the primary constraint.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end graphics card from the GeForce 30-series, built on the Ampere architecture and the GA102 chip. It is manufactured on an 8 nm process by Samsung and features a substantial 28,300 million transistors on a 628 mm² die. With a base clock of 1440 MHz and a boost clock of 1710 MHz, it is designed for high-performance rendering.

The card is equipped with 10 GB of GDDR6X memory on a 320-bit bus, providing a memory bandwidth of 760.3 GB/s. This is a crucial specification for higher resolutions and texture-heavy settings. The memory clock runs at 1188 MHz, translating to 19 Gbps effective. The GPU also features 8704 shading units, 272 TMUs, and 96 ROPs, which are the core building blocks for rasterization performance.

The RTX 3080's performance in the game data clearly shows it is the dominant component at higher resolutions. The 4K High preset's average of 78 FPS and the 4K Medium preset's 92 FPS demonstrate its raw power. The card's Passmark G3D score of 25086 places it in the 68th percentile of all GPUs, with its nearest rivals like the NVIDIA P106-100 and AMD Radeon RX 6600M being within a 0.4% performance delta, which is an unusual grouping for such a high-end card.

The GPU's 10 GB of VRAM appears sufficient for the tested settings, as there are no obvious signs of texture thrashing or severe performance drops that would indicate memory capacity issues. The scaling from Medium to High at 4K shows a drop from 92 FPS to 78 FPS, which is an expected cost for higher visual fidelity. The most demanding Ultra preset at 4K reduces the average to 63 FPS, showing that even a card like the RTX 3080 is taxed by the absolute maximum settings at 4K resolution in this title. The card's performance is the primary factor limiting frame rates at 1440p and 4K, while at 1080p, the CPU is more likely to be the constraint.
