AMD Radeon RX 6600 vs NVIDIA Quadro K5200 Comparison

The AMD Radeon RX 6600 decisively outperforms the NVIDIA Quadro K5200 in the benchmark data, winning both head-to-head tests by substantial margins. While the Quadro K5200 holds a marginal edge in average benchmark score when compared to the RX 6600's nearest rivals, the direct comparison reveals a generational gap in raw compute and graphics performance, with the RX 6600 leading by 34.1% in OpenCL and a staggering 70.2% in Vulkan.

Head-to-Head Benchmarks

The data presents a clear, two-test picture that favors the AMD Radeon RX 6600 overwhelmingly. In the Geekbench OpenCL test, the RX 6600 scores 28,850 against the Quadro K5200's 19,024. This represents a 34.1% advantage for the AMD card, a significant lead that indicates a substantial difference in general-purpose compute throughput. The Quadro's score of 19,024 places it in a competitive range with its nearest rivals—the AMD FirePro D300 (19,637, -0.2%) and the AMD Radeon RX 6650 XT (19,765, -0.8%)—but it is clearly outclassed by the RX 6600.

The disparity becomes even more pronounced in the Geekbench Vulkan test. Here, the RX 6600 delivers a score of 67,623, dwarfing the Quadro K5200's 20,180. The delta of -70.2% from the perspective of the Quadro highlights a massive performance gulf in modern graphics API workloads. This result is not a close contest; it is a dominant victory for the RDNA 2.0 architecture. The Quadro K5200's Vulkan score of 20,180 is far closer to its OpenCL result, whereas the RX 6600's Vulkan score is more than double its own OpenCL score, suggesting the AMD architecture is far better optimized for this modern API.

The overall win tally is 2-0 in favor of the AMD Radeon RX 6600. While the Quadro K5200 has a slightly higher average benchmark score (19,602) than the RX 6600 (19,036), this metric is skewed by the different sets of benchmarks available for each card. The direct head-to-head results are the most reliable indicator of relative performance, and they leave no room for ambiguity: the RX 6600 is the clear performance winner. The data does not show any benchmark where the Quadro K5200 manages to take a win, making the verdict on raw speed straightforward.

Architecture Differences

The two GPUs are built on fundamentally different architectures separated by seven years of technological advancement. The NVIDIA Quadro K5200 is based on the Kepler architecture, specifically the GK110B chip, manufactured on a 28 nm process node at TSMC. The AMD Radeon RX 6600 uses the RDNA 2.0 architecture with the Navi 23 chip, built on a much more advanced 7 nm process, also from TSMC. This process shrink is a core reason for the performance difference.

The transistor counts and die sizes tell a story of efficiency. The Quadro K5200 packs 7,080 million transistors on a large 561 mm² die, resulting in a transistor density of 12.6 million per square millimeter. In contrast, the RX 6600 contains 11,060 million transistors on a much smaller 237 mm² die, achieving a density of 46.7 million per square millimeter. This means the RX 6600 fits significantly more transistors into less than half the physical space, enabling higher clock speeds and greater efficiency.

The compute configurations also differ significantly. The Quadro K5200 has 2,304 shading units, 192 TMUs, and 48 ROPs. The RX 6600 has fewer shading units (1,792) and TMUs (112) but more ROPs (64). More importantly, the RX 6600 introduces 28 ray tracing cores (RT cores), a feature entirely absent from the older Kepler-based Quadro. The RX 6600 also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Quadro K5200 is limited to DirectX 12 (11_1) and Vulkan 1.2.175. This architectural leap in features is reflected in the Vulkan benchmark dominance.

Specification Differences

The specification sheets reveal a stark contrast in core technology and features. The most obvious difference is the process node: the Quadro K5200 uses 28 nm while the RX 6600 uses 7 nm. Clock speeds are dramatically different, with the Quadro's base clock at 667 MHz and boost at 771 MHz, while the RX 6600 runs at a 1626 MHz base and 2491 MHz boost clock. The RX 6600 also has a game clock of 2044 MHz, a metric the Quadro does not list.

Memory technology and bandwidth also differ. Both cards have 8 GB of memory, but the Quadro K5200 uses GDDR5 on a 256-bit bus, yielding 192.3 GB/s of bandwidth. The RX 6600 uses faster GDDR6 on a narrower 128-bit bus but achieves higher bandwidth at 224.0 GB/s. The memory clocks are 1502 MHz (6 Gbps effective) for the Quadro and 1750 MHz (14 Gbps effective) for the RX 6600.

The theoretical performance figures highlight the RX 6600's advantage. The RX 6600 has a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s, far exceeding the Quadro's 37.01 GPixel/s and 148.0 GTexel/s. FP32 performance is 8.928 TFLOPS for the RX 6600 versus 3.553 TFLOPS for the Quadro, and the RX 6600 also offers FP16 performance of 17.86 TFLOPS, which the Quadro does not list. The RX 6600 also has a lower TDP of 132 W compared to 150 W, requires a single 8-pin connector versus a 6-pin, and uses a PCIe 4.0 x8 interface versus PCIe 3.0 x16. The RX 6600 is also physically smaller at 190 mm in length compared to the Quadro's 267 mm.

Where Each One Wins

Based strictly on the data, the AMD Radeon RX 6600 wins in every measurable performance category. Its victories in both Geekbench OpenCL and Vulkan tests are substantial, making it the clear choice for any workload that benefits from high compute throughput or modern graphics API acceleration. The RX 6600's higher pixel rate, texture rate, and FP32 performance indicate it is superior for real-time rendering, gaming, and general-purpose GPU compute tasks. Its support for DirectX 12 Ultimate and ray tracing cores gives it a functional advantage in modern applications.

The NVIDIA Quadro K5200 has no wins in the head-to-head benchmarks. However, its average benchmark score of 19,602 is higher than the RX 6600's 19,036, and it sits at the 64th percentile versus the RX 6600's 63rd. This slight edge in the aggregate score, driven by its OpenCL result of 19,024, suggests that in certain narrow legacy compute scenarios, it may perform comparably to its contemporaries like the AMD FirePro D300 or NVIDIA GeForce GTX 1060 3 GB. Its 256-bit memory bus and 192.3 GB/s bandwidth, while lower than the RX 6600's, are still substantial. The Quadro's niche is its professional pedigree with display outputs including 2x DVI and 2x DisplayPort 1.2, which could be relevant for specific legacy workstation setups.

The Verdict

The data is unambiguous: the AMD Radeon RX 6600 is the superior performer. For any user prioritizing raw speed, modern API support, and efficiency, the RX 6600 is the definitive choice. Its 34.1% lead in OpenCL and 70.2% lead in Vulkan, combined with a smaller die, lower power draw, and newer feature set, make it the obvious pick from a pure performance standpoint.

The NVIDIA Quadro K5200 should only be considered by users with a specific need for its legacy professional features, such as its DVI outputs or compatibility with older Kepler-era software stacks. Its higher average benchmark score relative to the RX 6600 is a statistical artifact of the different benchmark suites and does not translate into a win in any direct comparison. For almost all modern workloads, the RX 6600 is not just a better choice; it is in a different performance class entirely.
