AMD Radeon RX 6600S vs NVIDIA GeForce GTX 760 Comparison

The Verdict

The recorded data presents a decisive outcome: the AMD Radeon RX 6600S holds a commanding lead over the NVIDIA GeForce GTX 760 in the only directly comparable benchmark, Geekbench OpenCL. The RX 6600S scores 66,435, which is 488% higher than the GTX 760's 11,299. This is not a marginal difference; it represents a generational leap in raw compute performance.

Looking at the broader database averages, the RX 6600S posts an average benchmark score of 10,629, placing it in the 49th percentile of all GPUs. The GTX 760 averages 9,458, sitting in the 46th percentile. While both cards are near the middle of the distribution, the RX 6600S is clearly ahead. Its nearest rivals in the database include the AMD Radeon R9 M275X (0.4% ahead), the NVIDIA GeForce GTX 560 Ti (0.6% behind), and the NVIDIA Quadro K2200 (1.2% behind). The GTX 760's nearest rivals are the NVIDIA GeForce GTX TITAN BLACK (0.2% behind), the AMD Radeon R7 M380 (1.6% ahead), and the NVIDIA GeForce GTX 850M (1.7% ahead).

For users choosing between these two, the RX 6600S is the clear pick for any workload involving OpenCL compute, which is the only head-to-head test available. The GTX 760, however, was a desktop card from an older generation and may still be relevant for legacy DirectX 9 or 10 workloads where the RX 6600S has no recorded comparable data. The RX 6600S is also the only one of the two with DirectX 12 Ultimate support, making it the forward-looking choice.

Architecture Differences

The architectural gap between these two GPUs is vast, reflecting nearly a decade of development. The AMD Radeon RX 6600S uses the Navi 23 chip built on RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. The chip contains 11,060 million transistors on a 237 mm² die, yielding a transistor density of 46.7 million per square millimeter. In contrast, the NVIDIA GeForce GTX 760 uses the GK104 chip based on Kepler architecture, built on a 28 nm process, also at TSMC. That chip holds 3,540 million transistors on a larger 294 mm² die, with a density of just 12.0 million per square millimeter.

The RX 6600S is a mobile part (Navi Mobile, RX 6000M generation) with an integrated form factor (IGP), no power connectors, and a TDP of 80 W. The GTX 760 is a desktop dual-slot card from the GeForce 700 generation, requiring 2x 6-pin power connectors and a 450 W suggested PSU, with a TDP of 170 W. The RX 6600S is markedly more power-efficient per unit of performance.

Memory configurations differ substantially. The RX 6600S has 4 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The GTX 760 has 2 GB of GDDR5 on a 256-bit bus, delivering 192.3 GB/s. Despite the narrower bus, the newer memory type gives the RX 6600S a bandwidth advantage. Clock speeds also favor the AMD part: the RX 6600S runs at a base of 1700 MHz, a boost of 2000 MHz, and a game clock of 1881 MHz, with memory at 14 Gbps effective. The GTX 760 operates at 980 MHz base and 1032 MHz boost, with memory at 6 Gbps effective.

Compute resources are heavily skewed toward the RX 6600S. It has 1,792 shading units, 112 texture mapping units, 64 raster output units, and 28 ray tracing cores. The GTX 760 has 1,152 shading units, 96 TMUs, and 32 ROPs, with no ray tracing cores. The RX 6600S achieves 7.168 TFLOPS FP32 and 14.34 TFLOPS FP16 (2:1 ratio), while the GTX 760 manages 2.378 TFLOPS FP32 and has no recorded FP16 capability. Pixel and texture rates also favor the AMD card: 128.0 GPixel/s and 224.0 GTexel/s versus 24.77 GPixel/s and 99.07 GTexel/s.

Interface and API support differ as well. The RX 6600S uses PCIe 4.0 x8, while the GTX 760 uses PCIe 3.0 x16. The AMD card supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the NVIDIA card supports DirectX 12 (11_0) and Vulkan 1.2.175. Both support OpenGL 4.6. The GTX 760 has a launch MSRP of 249 USD, a detail recorded in the database but not central to performance analysis.

Where Each One Wins

The RX 6600S wins the only recorded head-to-head benchmark, Geekbench OpenCL, by 488%. This is its clear domain. The architecture is designed for modern compute workloads, with FP16 support and ray tracing cores that the GTX 760 entirely lacks. For any task leveraging OpenCL, whether scientific compute, rendering, or modern game effects, the RX 6600S is overwhelmingly faster.

The GTX 760 has no recorded head-to-head wins. However, its benchmark portfolio includes Geekbench Metal (4,524) and Geekbench Vulkan (12,551), tests that the RX 6600S has no recorded scores for. In those specific API environments, the GTX 760 demonstrates functional capability, but without comparable RX 6600S data, no direct conclusion can be drawn. The GTX 760 also has a longer physical footprint at 241 mm (9.5 inches) and a dual-slot design, making it a traditional desktop card. The RX 6600S, being an IGP, is portable-device dependent and has no fixed dimensions.

For legacy DirectX 9 and 10 workloads, the GTX 760's architecture from 2013 may have mature driver paths, but the RX 6600S has no recorded PassMark DirectX 9 or 10 scores in the database. The RX 6600S does have PassMark scores for DirectX 11 (105), DirectX 12 (56), G2D (647), G3D (12,649), and GPU Compute (4,879). The GTX 760 has no PassMark scores recorded at all. This means the RX 6600S is the only one of the two with measurable legacy DirectX performance in the database.

Head-to-Head Benchmarks

The single recorded head-to-head benchmark is Geekbench OpenCL, and the result is emphatic. The RX 6600S scores 66,435, while the GTX 760 scores 11,299. The delta is 488%, meaning the AMD card is nearly six times faster in this workload. This is the largest margin in the entire comparison and reflects the fundamental architectural differences: the RX 6600S uses a 7 nm RDNA 2.0 design with 7.168 TFLOPS FP32 throughput, versus the GTX 760's 28 nm Kepler design at 2.378 TFLOPS.

The RX 6600S also holds a decisive edge in every resource category. Its 1,792 shading units outnumber the GTX 760's 1,152 by more than 50%. Its 64 ROPs double the GTX 760's 32. The texture rate of 224.0 GTexel/s is more than double the GTX 760's 99.07 GTexel/s. Pixel rate is even more lopsided: 128.0 GPixel/s versus 24.77 GPixel/s, a factor of over five. Memory bandwidth favors the RX 6600S at 224.0 GB/s versus 192.3 GB/s, a smaller but still meaningful advantage.

The GTX 760 does have recorded scores in Geekbench Metal (4,524) and Geekbench Vulkan (12,551), but the RX 6600S has no recorded scores in those tests. Therefore, no head-to-head comparison is possible for those APIs. The GTX 760's Vulkan score of 12,551 is higher than its OpenCL score of 11,299, suggesting the Kepler architecture handles Vulkan reasonably well. However, the RX 6600S's OpenCL dominance indicates that in any modern compute scenario, the AMD card will be vastly superior.

In terms of overall database standing, the RX 6600S's average score of 10,629 puts it 12.4% ahead of the GTX 760's 9,458. The percentile ranks confirm this: 49th versus 46th. The nearest rival data further contextualizes the RX 6600S: it is 0.4% ahead of the Radeon R9 M275X and 1.4% ahead of the Radeon RX 550X, while trailing the GTX 560 Ti by 0.6% and the Quadro K2200 by 1.2%. The GTX 760 sits 0.2% behind the GTX TITAN BLACK and 1.6% to 1.8% ahead of the R7 M380, GTX 850M, and GTX 465. These tight margins around each card indicate that both occupy competitive positions within their own eras, but the RX 6600S is clearly in a higher performance tier.

The production status of both cards is end-of-life. The RX 6600S was released in January 2022, while the GTX 760 was released in June 2013. The GTX 760's successor is the GeForce 900 series, and its predecessor was the GeForce 600. The RX 6600S's predecessor was Polaris Mobile, and it has no recorded successor. For anyone deciding today based on the recorded data, the RX 6600S is the only rational choice for compute performance. The GTX 760 remains a historical artifact with niche relevance only in APIs where the RX 6600S has no recorded scores.
