The GPU operates with a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. Memory runs at 2190 MHz (17.5 Gbps effective) across 8 GB of GDDR6 on a 128-bit bus, yielding 280.3 GB/s of bandwidth. The card features 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray accelerators, producing a pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s. Floating-point performance is rated at 10.79 TFLOPS for FP32 and 21.59 TFLOPS for FP16 (2:1 ratio).

The GPU's PassMark G3D score of 17,166 places it in the 65th percentile among all GPUs, with an average benchmark score of 19,765. Its nearest rivals in the benchmark database include the NVIDIA Tesla K40m (19,885, -0.6% delta), AMD FirePro D300 (19,637, +0.7%), AMD FirePro W7000 (19,905, -0.7%), and NVIDIA Quadro K5200 (19,602, +0.8%). These deltas are all within 1%, indicating that the RX 6650 XT performs in a tightly contested band around the 19,700–19,900 score range.

In Doom specifically, the GPU's role is pivotal across all measured resolutions. At 1920x1080, the card delivers 200 FPS on Low, 174 FPS on Medium, 147 FPS on High, and 120 FPS on Ultra. The scaling from Low to Ultra at 1080p shows a 40% drop in average FPS, which is a typical penalty for increasing graphical fidelity in this title. At 2560x1440, the averages are 129 FPS (Low), 113 FPS (Medium), 95 FPS (High), and 78 FPS (Ultra). The 1440p Ultra result represents a 35% reduction compared to 1080p Ultra, while 1440p Low is 35.5% lower than 1080p Low.

At 3840x2160, the GPU begins to strain. Average FPS drops to 70 on Low, 61 on Medium, 51 on High, and 42 on Ultra. The 4K Ultra result is exactly 21% of the 1080p Low figure, highlighting how heavily the RX 6650 XT is burdened at 4K with maximum settings. The 4K Medium row includes a recorded minimum of 52 FPS and maximum of 70 FPS, showing a 18 FPS spread in frame times. The 8 GB VRAM capacity, while adequate at 1080p and 1440p, appears insufficient to maintain high frame rates at 4K with Ultra presets, as the 42 FPS average suggests texture and geometry demands outpace the memory bandwidth.

# CPU Role

The AMD Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture (codenamed Vermeer), fabricated on TSMC's 7 nm process. It features a base clock of 3.00 GHz and a boost clock of 4.00 GHz, with a 65 W TDP. The CPU uses the AMD Socket AM4 platform and supports DDR4 memory in a dual-channel configuration with a theoretical bandwidth of 51.2 GB/s. Cache consists of 64 KB L1 per core, 512 KB L2 per core, and 32 MB shared L3. The chip integrates no graphics, is multiplier-unlocked, and communicates via PCIe Gen 4 with 20 CPU lanes. The transistor count is 4,150 million on a die size of 74 mm², and the processor supports ECC memory.

In synthetic benchmarks, the Ryzen 5 5600F posts a PassMark single-thread score of 2872 and a multithread score of 19,236. Other relevant scores include floating-point math at 34,548, integer math at 59,339, extended instructions at 16,266, and prime number finding at 120. The average benchmark score is 36,945, placing the CPU in the 85th percentile of all processors. Its nearest rivals are closely matched: the Intel Core Ultra 5 225 (36,938, 0% delta) is effectively identical, while the AMD Ryzen 5 5500X3D (37,018, -0.2%), AMD Ryzen AI 7 PRO 450 (37,093, -0.4%), and Intel Core i9-12900T (37,112, -0.5%) all sit marginally higher.

For Doom, a game released in May 2016, the CPU's role is to feed the GPU with draw calls and game logic without becoming a bottleneck. The 6-core, 12-thread configuration with a 4.00 GHz boost clock is more than sufficient for this title, which was designed for the era of quad-core processors. The high single-thread score of 2872 ensures that the game's primary thread, which typically handles input, physics, and AI, runs efficiently. The multithread score of 19,236 provides headroom for background tasks and any additional threads Doom may spawn, though the game's engine is primarily single-thread bound in many scenarios.

The measured FPS data in Doom shows that the CPU does not appear to be a limiting factor at any resolution tested. At 1920x1080 with Low settings, the combo reaches 200 FPS, which is close to the display refresh ceiling for most monitors and well above the 144 Hz standard for gaming panels. Even at 4K Ultra, where the GPU is clearly struggling at 42 FPS, the CPU is unlikely to be the constraint given its percentile ranking. The 85th percentile placement among all CPUs underscores that the 5600F is a capable mid-range processor that pairs well with the RX 6650 XT for this game.

# Measured FPS Breakdown

At 1920x1080, the AMD Ryzen 5 5600F and Radeon RX 6650 XT combination delivers its strongest results. With Low settings, the average FPS is 200. Moving to Medium, the average drops to 174, with a recorded minimum of 148 FPS and maximum of 200 FPS. High settings yield 147 FPS average, and Ultra settings produce 120 FPS average. The progression from Low to Ultra shows a stepwise decrement: 13% from Low to Medium, 15.5% from Medium to High, and 18.4% from High to Ultra. The Medium preset's minimum of 148 FPS ensures that the frame rate never dips below the 144 Hz threshold, while the 120 FPS Ultra average still provides smooth gameplay on standard 60 Hz displays.

At 2560x1440, the same settings hierarchy produces lower but still playable numbers. Low settings average 129 FPS, Medium averages 113 FPS with a minimum of 96 and maximum of 129, High averages 95 FPS, and Ultra averages 78 FPS. The delta between Low and Ultra at 1440p is 39.5%, slightly steeper than the 40% observed at 1080p. The Medium preset's minimum of 96 FPS is within the range of high-refresh-rate monitors, though the 96 FPS floor is close to the 100 FPS mark. Ultra at 78 FPS is still above the 60 FPS baseline, making it viable for 1440p gaming with maximum settings.

At 3840x2160, performance becomes noticeably constrained. Low settings average 70 FPS, Medium averages 61 FPS with a minimum of 52 and maximum of 70, High averages 51 FPS, and Ultra averages 42 FPS. The scaling from Low to Ultra at 4K is a 40% reduction, similar to the other resolutions. However, the absolute numbers are lower: only the Low preset exceeds 60 FPS, while High and Ultra fall below the 60 FPS threshold, which is often considered the minimum for comfortable gaming. The Medium preset's minimum of 52 FPS indicates occasional frame drops that could be noticeable in fast-paced action sequences, though the average of 61 FPS is still playable.

Cross-resolution comparisons reveal the GPU's scaling behavior. At Low settings, moving from 1080p to 1440p reduces FPS by 35.5% (from 200 to 129), and from 1440p to 4K reduces it by 45.7% (from 129 to 70). At Ultra settings, the reductions are 35% from 1080p to 1440p (120 to 78) and 46.2% from 1440p to 4K (78 to 42). These consistent percentages indicate that the GPU scales predictably with pixel count, with the 4K jump being the most demanding due to the quad-pixel increase from 1080p.

# How This Combo Ranks

In Doom, the AMD Ryzen 5 5600F and Radeon RX 6650 XT combination ranks 1886th out of 2930 tested combinations. This places the combo in the 64th percentile of all configurations tested for this game, meaning roughly 64% of combinations outperform it. The rank is consistent with the GPU's overall percentile of 65 and the CPU's percentile of 85, suggesting that the GPU is the primary limiting factor in this pairing.

The CPU's high percentile (85) relative to the combo's rank (64th percentile) indicates that the Ryzen 5 5600F is not the bottleneck; rather, the RX 6650 XT's 65th percentile GPU ranking pulls the overall performance down. The GPU's nearest rivals in the database—the NVIDIA Tesla K40m, AMD FirePro D300, AMD FirePro W7000, and NVIDIA Quadro K5200—are all professional or older workstation cards, which underscores that the RX 6650 XT sits in a niche between consumer gaming GPUs and prosumer offerings. Despite this, the combo's rank in Doom reflects the game's optimization for mainstream hardware, as the 1886th position out of 2930 suggests it outperforms a significant portion of tested systems.

The data indicates that the combo is well-balanced for 1080p and 1440p gaming, where the GPU can leverage the CPU's strong single-thread performance to deliver high frame rates. At 4K, the rank would likely be lower if only that resolution were considered, given the GPU's 42 FPS Ultra result. However, the overall rank of 1886/2930 is a composite measure that includes all tested resolutions and settings, providing a holistic view of the combo's capabilities.

# Settings Recommendations

For 1920x1080 displays, the Ultra preset at 120 FPS average is the optimal choice for players seeking maximum visual fidelity without sacrificing smoothness. The 120 FPS average is well above the 60 FPS minimum and approaches the refresh rate of 144 Hz monitors. If a higher frame rate is desired, the High preset at 147 FPS offers a 22.5% improvement over Ultra while still maintaining high graphical quality. The Low preset at 200 FPS is only recommended for competitive play where frame rate outweighs visuals, as the graphical downgrade is substantial.

At 2560x1440, the High preset at 95 FPS provides the best balance of image quality and performance. The Ultra preset at 78 FPS is still playable and delivers the full visual experience, but the 17.9% FPS gain from dropping to High is noticeable on high-refresh-rate displays. The Medium preset at 113 FPS is the best choice for 144 Hz monitors, as it maintains an average above 100 FPS while keeping the minimum at 96 FPS. The Low preset at 129 FPS is viable for competitive play but sacrifices too much visual detail for most players.

At 3840x2160, the Medium preset at 61 FPS is the recommended starting point, as it is the only preset above the 60 FPS average threshold aside from Low. The Medium preset's minimum of 52 FPS is the lowest recorded value across all resolutions and settings, indicating that frame pacing may be inconsistent. The Low preset at 70 FPS is the safest choice for maintaining a consistent 60+ FPS experience at 4K, though it requires significant graphical compromises. The High preset at 51 FPS and Ultra at 42 FPS are not recommended for comfortable gameplay, as they fall below the 60 FPS standard and may induce noticeable stutter during intense combat scenes. For 4K users, the data suggests that either accepting the Low preset's visual downgrade or lowering the resolution to 1440p with High settings (95 FPS) yields a markedly better experience.
