Doom

How This Combo Ranks

The Intel Core Ultra 7 265 paired with the AMD Radeon RX 6650 XT sits at rank 1886 out of 2930 tested combos for Doom. That places this pairing in the lower-middle portion of the field, meaning roughly 64% of tested combinations deliver higher average frame rates in this title. The ranking reflects a system that can play Doom comfortably at most settings, but it is not a top-tier performer by any stretch.

The CPU itself is a strong component in isolation. Its average benchmark score of 64,640 places it in the 93rd percentile of all CPUs tested. The nearest rivals tell a tight story: the AMD EPYC 4464P scores 64,823 (0.3% higher), the Intel Core Ultra 7 265F scores 64,438 (0.3% lower), the AMD EPYC 7343 scores 64,202 (0.7% lower), and the AMD EPYC 9124 scores 65,104 (0.7% higher). All four rivals sit within a 1.4% band, which means the 265 is essentially tied with them in raw compute. For Doom, though, the GPU becomes the dominant factor, and that is where this combo loses ground.

The GPU's average benchmark score of 19,765 places it in the 65th percentile of all GPUs, which is respectable but not exceptional. Its nearest rivals include the NVIDIA Tesla K40m (19,885, 0.6% higher), the AMD FirePro D300 (19,637, 0.7% lower), the AMD FirePro W7000 (19,905, 0.7% higher), and the NVIDIA Quadro K5200 (19,602, 0.8% lower). The RX 6650 XT is thus surrounded by older workstation cards in synthetic tests, but its real-world Doom performance is what matters here.

The combination rank of 1886 suggests the CPU is not the limiting factor. In fact, the 265's 20 cores and 20 threads, with a boost clock of 5.30 GHz, provide far more headroom than Doom's engine requires. The bottleneck is the GPU's 8 GB of VRAM and its 128-bit memory bus, which constrains performance at higher resolutions and settings. This is a classic pairing where a mid-range GPU holds back a high-end CPU, and the rank reflects that imbalance.

FAQ

Q: Is the Intel Core Ultra 7 265 overkill for this GPU?

A: Yes. The CPU scores in the 93rd percentile of all processors, while the GPU sits in the 65th percentile. In Doom, the GPU is the limiting component, so the CPU's extra headroom goes unused.

Q: Can this combo handle Doom at 4K?

A: Yes, but with compromises. At 4K Ultra, the average FPS drops to 42, which is below the 60 FPS threshold. Dropping to 4K High raises it to 51 FPS, and 4K Medium hits 61 FPS. Only 4K Low reaches a comfortable 70 FPS average.

Q: What is the best resolution for this pairing?

A: 1440p is the sweet spot. At 1440p High, the average FPS is 95, and at 1440p Ultra it drops to 78 FPS. Both are playable, but 1440p High offers a better balance of visual quality and smoothness.

Q: How does the RX 6650 XT compare to its nearest rivals in synthetic benchmarks?

A: The GPU's average score of 19,765 is within 0.8% of all four nearest rivals. The NVIDIA Tesla K40m is 0.6% higher, the AMD FirePro D300 is 0.7% lower, the AMD FirePro W7000 is 0.7% higher, and the NVIDIA Quadro K5200 is 0.8% lower. These are essentially statistical ties.

Q: Does the CPU's 20-core configuration help in Doom?

A: No. Doom is a GPU-bound title at the settings tested. The CPU's multi-core strength, shown by a Cinebench R23 multi-core score of 42,216, does not translate to higher FPS because the GPU saturates first.

Q: Is there a significant FPS gap between Low and Ultra settings?

A: Yes. At 1080p, Low averages 200 FPS while Ultra averages 120 FPS, a 40% drop. At 1440p, the gap is from 129 FPS (Low) to 78 FPS (Ultra), a 39.5% drop. At 4K, Low averages 70 FPS and Ultra averages 42 FPS, a 40% drop. The scaling is consistent across resolutions.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip. It features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The memory clock runs at 2190 MHz, which translates to 17.5 Gbps effective. The GPU's base clock is 2055 MHz, with a boost clock of 2635 MHz and a game clock of 2410 MHz. These clocks are competitive for the card's class, but the 8 GB VRAM capacity is the key limitation in Doom at higher settings.

The card has 2048 shading units, 128 texture mapping units, and 64 raster operation units. It also includes 32 ray tracing cores, though Doom (2016) does not use ray tracing, so those cores go unused. The pixel rate is 168.6 GPixel/s and the texture rate is 337.3 GTexel/s. The FP32 performance is 10.79 TFLOPS, which is adequate for a game of Doom's era.

In the measured FPS data, the GPU's role is clear. At 1080p Low, the card pushes 200 FPS average, showing it can handle light loads easily. At 1080p Ultra, it drops to 120 FPS, a 40% reduction. The same pattern holds at 1440p (129 FPS Low to 78 FPS Ultra) and 4K (70 FPS Low to 42 FPS Ultra). The GPU is the sole determinant of these swings; the CPU's performance is constant across all runs.

The 8 GB VRAM is sufficient for Doom at 1080p and 1440p, but at 4K Ultra, the card likely runs into memory pressure. The fact that 4K Medium produces 61 FPS while 4K Ultra produces 42 FPS suggests that the higher settings require more memory bandwidth and capacity than the 128-bit bus can efficiently provide. The GPU's 65th percentile ranking among all GPUs confirms it is a mid-tier part, and Doom's results align with that placement.

Measured FPS Breakdown

At 1080p, the RX 6650 XT delivers strong performance across all settings. Low settings average 200 FPS, which is the highest measured value in the entire dataset. Medium settings average 174 FPS with a minimum of 148 FPS and a maximum of 200 FPS. High settings average 147 FPS, and Ultra settings average 120 FPS. The jump from Low to Ultra is a 40% performance loss, but even the lowest value of 120 FPS is well above the 60 FPS standard for smooth gameplay.

At 1440p, the card shows its mid-range nature. Low settings average 129 FPS, which is still excellent. Medium settings average 113 FPS with a minimum of 96 FPS and a maximum of 129 FPS. High settings average 95 FPS, and Ultra settings average 78 FPS. Every setting at 1440p remains playable, with Ultra still holding above 75 FPS. The scaling from 1080p to 1440p is roughly a 35% drop at each setting level, which is typical for a card with this memory bandwidth.

At 4K, the card struggles to maintain high frame rates. Low settings average 70 FPS, which is playable but not ideal. Medium settings average 61 FPS with a minimum of 52 FPS and a maximum of 70 FPS, putting it right at the edge of the 60 FPS target. High settings average 51 FPS, and Ultra settings drop to 42 FPS. The 4K Ultra result is the weakest in the dataset, and it clearly shows the GPU's limitations at this resolution.

The Medium settings rows are the only ones that include minimum and maximum FPS values. At 1080p Medium, the range is 148 to 200 FPS. At 1440p Medium, it is 96 to 129 FPS. At 4K Medium, it is 52 to 70 FPS. These ranges show that frame pacing is consistent; the minimums are not egregiously lower than the averages, which indicates stable performance without major hitches.

Resolution Scaling

The FPS drop from 1080p to 4K is consistent and predictable. At Low settings, 1080p averages 200 FPS, 1440p averages 129 FPS (a 35.5% drop), and 4K averages 70 FPS (a 45.7% drop from 1440p). At Medium settings, the progression is 174 FPS to 113 FPS (35.1% drop) to 61 FPS (46.0% drop). At High settings, it is 147 FPS to 95 FPS (35.4% drop) to 51 FPS (46.3% drop). At Ultra settings, it is 120 FPS to 78 FPS (35.0% drop) to 42 FPS (46.2% drop).

The pattern is remarkably uniform: moving from 1080p to 1440p costs roughly 35% of the frame rate, and moving from 1440p to 4K costs another 46%. This indicates that the GPU is scaling with the pixel count in a linear fashion, which is expected for a card that is fully utilized at all resolutions. The CPU is not introducing any bottlenecks, as the FPS drops are purely a function of the GPU's rendering workload.

The uniform scaling also reveals that the limiting component is the GPU. If the CPU were the bottleneck, we would expect to see smaller FPS drops at higher resolutions, because the GPU would become more saturated and the CPU would have more time to feed it. Instead, the FPS drops are proportional to the pixel count increase, which confirms that the RX 6650 XT is running at near-maximum utilization even at 1080p.

The 4K results are particularly telling. The card cannot maintain 60 FPS at 4K High or Ultra, and even 4K Medium only hits 61 FPS on average with a 52 FPS minimum. This means that for 4K gaming, the user would need to use Low settings to stay above 60 FPS, which defeats the purpose of 4K resolution. The 8 GB VRAM and 128-bit bus are simply not enough for 4K at higher presets.

Settings Recommendations

For the best experience with this combo, the data points strongly toward 1440p High. This setting averages 95 FPS, which is smooth and responsive, while still offering a significant visual upgrade over Low settings. The 1440p Ultra preset averages 78 FPS, which is also playable, but the 17 FPS gain from dropping from Ultra to High is worth the minor visual compromise. If you have a 1440p monitor, High is the clear choice.

At 1080p, the situation is different. The card has enough headroom to run Ultra at 120 FPS, which is excellent. If you are on a 1080p display, there is no reason to use anything below Ultra, as the 120 FPS average is well above the refresh rate of most monitors. The 1080p Medium setting at 174 FPS is overkill for standard 60 Hz or 144 Hz displays, so Ultra provides the best visual quality without sacrificing playability.

At 4K, the recommendations are more constrained. The only setting that maintains a 60 FPS average is Low, which hits 70 FPS. Medium averages 61 FPS but has a 52 FPS minimum, which could cause noticeable stutters in fast-paced combat. If you must play at 4K, Low settings are the safe choice. High and Ultra are not recommended, as 51 FPS and 42 FPS averages will feel sluggish in Doom's action-heavy gameplay.

The Medium settings rows provide the only min/max data in the dataset, which gives insight into frame consistency. At 1440p Medium, the 96 FPS minimum is close to the 113 FPS average, indicating stable performance. At 4K Medium, the 52 FPS minimum is concerning, as it falls below the 60 FPS threshold. This suggests that 4K Medium is borderline, and users prone to motion sickness or frame pacing sensitivity should avoid it.

Overall, the best experience per the measured rows is 1440p High. It offers a 95 FPS average with no min/max data to suggest instability, and it sits comfortably above the 60 FPS standard. For users with 1080p displays, Ultra is the pick. For 4K users, Low is the only acceptable option, and even then, the experience will not match what the card delivers at lower resolutions.
