FAQ

Q: What is the average FPS at 1080p Ultra settings for this AMD Ryzen 5 3600 + Radeon RX 6650 XT combo in Thief?

A: The measured average FPS at 1920x1080 with Ultra settings is 88.1 frames per second. This is the lowest average at 1080p across all settings presets, with Low producing 127.9 FPS and Medium producing 114.2 FPS.

Q: How does the CPU compare to its nearest rival in overall benchmark scores?

A: The Ryzen 5 3600 has an average benchmark score of 18129, which is essentially tied with the Intel Core i5-11400 (18150, deltaPct -0.1%). It also sits within 0.3% of the AMD EPYC 9274F (18189), indicating near-identical aggregate performance among these processors.

Q: What is the GPU's percentile ranking among all tested graphics cards?

A: The AMD Radeon RX 6650 XT ranks in the 72nd percentile among all GPUs. Its average benchmark score of 29024 is effectively matched by the AMD Radeon RX 6800M (29011, deltaPct 0%) and slightly ahead of the AMD Radeon RX 470 (28996, deltaPct 0.1%).

Q: What is the performance gap between 1080p and 4K at High settings?

A: At High settings, the average FPS drops from 96.0 at 1920x1080 to 39.1 at 3840x2160, representing a 59.3% reduction in frame rate. The 4K result falls below the 40 FPS threshold, indicating the GPU becomes the limiting factor at that resolution.

Q: Does the combo rank in the top half of tested combinations for Thief?

A: Yes, this combo ranks 1200th out of 1642 tested combinations, placing it in the 73rd percentile of all combos. This aligns closely with the GPU's own 72nd percentile ranking, suggesting the pairing performs consistently with expectations.

Q: What memory configuration does the GPU use and what is its bandwidth?

A: The GPU features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of memory bandwidth. The memory clock is listed at 2190 MHz with an effective data rate of 17.5 Gbps.

GPU Role

The AMD Radeon RX 6650 XT, built on the RDNA 2.0 architecture with the Navi 23 chip, provides the graphical muscle for this pairing. Its 8 GB of GDDR6 memory across a 128-bit interface yields 280.3 GB/s of bandwidth, a figure that proves adequate for Thief's 2014-era engine demands. The GPU operates at a base clock of 2055 MHz, with a game clock of 2410 MHz and a boost clock of 2635 MHz. These clock speeds, combined with 2048 shading units, 128 texture mapping units, and 64 raster operation units, deliver a pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s.

The card's FP32 throughput of 10.79 TFLOPS places it firmly in the mid-range segment of its generation, and its 72nd percentile ranking among all GPUs confirms this positioning. Interestingly, the GPU's nearest rivals include the AMD Radeon RX 6800M (29011, deltaPct 0%) and the AMD Radeon RX 470 (28996, deltaPct 0.1%), showing that the 6650 XT's aggregate benchmark performance is remarkably close to both a mobile flagship and an older desktop part. The data also indicates the RX 6650 XT trails the Intel Arc A370M by only 0.5% (29175 vs 29024) and the AMD Radeon RX Vega M GH by 0.6% (29197 vs 29024), making this a tightly contested performance tier.

In Thief specifically, the GPU's role becomes apparent when examining the measured FPS across settings. At 1080p, the gap between Low (127.9 FPS) and Ultra (88.1 FPS) is 39.8 FPS, demonstrating that the GPU has enough headroom to handle increased graphical fidelity without collapsing. The 4K results tell a different story, where Ultra settings produce just 38.5 FPS and High produces 39.1 FPS, both below the 40 FPS mark. This indicates that at 4K, the GPU's 8 GB memory buffer and 280.3 GB/s bandwidth become constrained by the engine's demands at higher resolutions.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution scaling that shifts the bottleneck between CPU and GPU. At 1080p Low settings, the combo produces 127.9 FPS, which suggests the CPU (with its 6 cores and 12 threads based on Zen 2 architecture) is capable of feeding the GPU adequately at lower graphical loads. Moving from 1080p to 1440p at Low settings reduces average FPS from 127.9 to 109.9, a 14.1% drop. However, the jump from 1440p to 4K at Low settings is far more dramatic, falling from 109.9 to 64.7 FPS, a 41.1% reduction.

This non-linear scaling indicates that at lower resolutions and settings, the system is partially CPU-limited, while at 4K, the GPU becomes the dominant constraint. The High settings preset illustrates this even more clearly: 1080p High produces 96.0 FPS, 1440p High drops to 63.3 FPS (34.1% reduction), and 4K High falls to 39.1 FPS (38.2% reduction from 1440p). The 4K High result being below 40 FPS suggests the RX 6650 XT's 8 GB memory and 280.3 GB/s bandwidth are insufficient for smooth gameplay at that resolution with higher quality settings.

Ultra settings follow a similar trajectory but with lower absolute values: 88.1 FPS at 1080p, 63.1 FPS at 1440p, and 38.5 FPS at 4K. The percentage drop from 1080p to 1440p at Ultra is 28.4%, while the drop from 1440p to 4K is 39.0%. These figures suggest that the scaling penalty accelerates as resolution increases, a classic sign of GPU-bound rendering where the card's memory bandwidth becomes the limiting factor. The CPU's 32 MB shared L3 cache and dual-channel DDR4 memory with 51.2 GB/s bandwidth appear sufficient to avoid becoming the primary bottleneck until the GPU is fully saturated.

Measured FPS Breakdown

At 1920x1080, the combo delivers playable frame rates across all settings. Low settings produce 127.9 FPS average, Medium produces 114.2 FPS, High produces 96.0 FPS, and Ultra produces 88.1 FPS. The spread from Low to Ultra is 39.8 FPS, which represents a 31.1% performance penalty for maximum quality. All 1080p results exceed 85 FPS, making this resolution ideal for high-refresh-rate displays.

Moving to 2560x1440, the performance remains respectable but begins to show the GPU's limitations. Low settings yield 109.9 FPS, which is still above the 100 FPS mark, while Medium drops to 83.3 FPS and High falls to 63.3 FPS. Ultra settings at 1440p produce 63.1 FPS, nearly identical to High, suggesting that the engine's Ultra preset at this resolution may be hitting a memory bandwidth ceiling rather than a shading throughput limit.

At 3840x2160, the results are more challenging. Low settings produce 64.7 FPS, which is playable, but Medium drops to 49.7 FPS, High to 39.1 FPS, and Ultra to 38.5 FPS. The 4K Ultra result is 43.7% lower than the 1080p Ultra result, and both High and Ultra at 4K fall below the 40 FPS threshold, indicating that 4K gaming with this combo requires either Low settings or a reduction in resolution. The data shows that at 4K, the gap between High (39.1 FPS) and Ultra (38.5 FPS) is negligible, further confirming that the GPU is the limiting component rather than the CPU.

How This Combo Ranks

This AMD Ryzen 5 3600 + AMD Radeon RX 6650 XT combination ranks 1200th out of 1642 tested combos in Thief, placing it in the 73rd percentile. This ranking is notably consistent with the GPU's 72nd percentile position among all GPUs, suggesting that the CPU is not significantly holding back the graphics card in this title. The CPU itself ranks in the 76th percentile among all CPUs, slightly higher than the combo's overall ranking, which implies that the GPU is the more constraining component in this pairing.

The CPU's nearest rivals include the Intel Core i5-11400 (deltaPct -0.1%), AMD Ryzen 5 7535HS (deltaPct 0.2%), AMD Ryzen 5 1600 (deltaPct -0.2%), and AMD EPYC 9274F (deltaPct -0.3%). All of these processors are within 0.3% of the Ryzen 5 3600's average benchmark score of 18129, meaning that swapping to any of these CPUs would likely produce nearly identical results in Thief. This tight clustering indicates that the game is not particularly sensitive to CPU differences within this performance tier.

The GPU's nearest rivals similarly show minimal performance deltas: the AMD Radeon RX 6800M (0%), AMD Radeon RX 470 (0.1%), Intel Arc A370M (-0.5%), and AMD Radeon RX Vega M GH (-0.6%). The fact that the RX 6650 XT's aggregate performance is within 0.6% of these four different architectures reinforces that the combo's 1200th place ranking is driven more by the GPU's absolute capability than by any pairing inefficiency. The benchmark results indicate that this combo occupies a solid mid-tier position, capable of 1080p Ultra and 1440p High gameplay without compromise, but requiring settings reductions for 4K.
