AMD Radeon RX 6600S vs NVIDIA GeForce GTX 460 v2 Comparison

Head-to-Head Benchmarks

The recorded database contains a single common benchmark between these two parts: Geekbench OpenCL. In that test, the AMD Radeon RX 6600S delivers a score of 66,435, while the NVIDIA GeForce GTX 460 v2 manages 8,743. The result is a decisive 659.9% advantage for the AMD part, a margin that reflects the generational gulf between the two products.

To put that score in context, the RX 6600S sits at the 49th percentile among all GPUs in the database, with an average benchmark score of 10,629 across all recorded tests. Its nearest rivals include the AMD Radeon R9 M275X (10,582, a 0.4% gap), the NVIDIA GeForce GTX 560 Ti (10,690, a 0.6% deficit), and the AMD Radeon RX 550X (10,481, a 1.4% lead). The GTX 460 v2, by contrast, holds the 44th percentile with an average score of 8,743. Its nearest rivals are the NVIDIA GeForce RTX 3050 A Mobile (8,746, effectively a tie), the NVIDIA Quadro P2200 (8,686, a 0.7% deficit), and the AMD Radeon R9 M265X (8,851, a 1.2% gap).

The head-to-head data shows one win for the RX 6600S and zero for the GTX 460 v2. This is not a close contest. The AMD part is over seven and a half times faster in the sole shared workload. Even accounting for the fact that the GTX 460 v2 has only one recorded benchmark in the database, the scale of the delta leaves little room for ambiguity about which part is faster in raw compute throughput.

Architecture Differences

The two GPUs come from different architectural eras entirely. The AMD Radeon RX 6600S is built on RDNA 2.0, using the Navi 23 chip, fabricated on a 7 nm process at TSMC. The NVIDIA GeForce GTX 460 v2 uses the Fermi 2.0 architecture with the GF114 chip, built on a 40 nm process, also at TSMC. The process node difference alone, 7 nm versus 40 nm, explains a substantial portion of the performance and efficiency gap.

Transistor counts and die sizes reinforce the generational split. The Navi 23 chip packs 11,060 million transistors into a 237 mm² die, yielding a density of 46.7 million transistors per square millimeter. The GF114 chip holds 1,950 million transistors across a larger 332 mm² die, resulting in just 5.9 million transistors per square millimeter. The AMD part achieves roughly eight times the transistor density on a smaller physical die, a direct consequence of the more advanced manufacturing process.

Memory subsystems also differ sharply. The RX 6600S uses 4 GB of GDDR6 on a 128-bit bus, with a memory clock of 1750 MHz (14 Gbps effective) and bandwidth of 224.0 GB/s. The GTX 460 v2 uses 1 GB of GDDR5 on a 192-bit bus, with a memory clock of 1002 MHz (4 Gbps effective) and bandwidth of 96.19 GB/s. The AMD part has four times the capacity and over twice the bandwidth, despite the narrower bus, thanks to the faster memory type.

Compute resources are similarly lopsided. The RX 6600S has 1,792 shading units, 112 texture mapping units, and 64 ROPs. It also includes 28 ray tracing cores, a feature class entirely absent from the Fermi-based GTX 460 v2. The NVIDIA part has 336 shading units, 56 TMUs, and 24 ROPs. Pixel rate for the AMD part is 128.0 GPixel/s versus 10.91 GPixel/s for the NVIDIA part. Texture rate is 224.0 GTexel/s versus 43.62 GTexel/s. FP32 throughput is 7.168 TFLOPS versus 1,046.3 GFLOPS (roughly 1.05 TFLOPS). The AMD part also supports FP16 at 14.34 TFLOPS (2:1 ratio), while the GTX 460 v2 has no recorded FP16 capability.

API support further separates the pair. The RX 6600S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GTX 460 v2 supports DirectX 12 (11_0), OpenGL 4.6, and has no Vulkan support listed. The AMD part also uses PCIe 4.0 x8, while the NVIDIA part uses the older PCIe 2.0 x16 interface.

Power and physical design are in different categories. The RX 6600S is rated at 80 W TDP, is an IGP-class slot width, and requires no power connectors. The GTX 460 v2 is rated at 160 W TDP, is a dual-slot card, requires two 6-pin power connectors, and lists a 450 W suggested PSU. The NVIDIA card measures 210 mm (8.3 inches) in length. The AMD part has no recorded physical dimensions.

Where Each One Wins

The RX 6600S wins in every measurable category where both parts have data. In the single shared benchmark, Geekbench OpenCL, it holds a 659.9% lead. In architecture, it wins on process node, transistor density, memory capacity, memory bandwidth, compute unit count, ray tracing support, API level, and power efficiency. The 80 W TDP versus 160 W TDP is particularly notable: the AMD part delivers dramatically higher performance while consuming half the power.

The GTX 460 v2 has no recorded wins in the database. Its only benchmark score, 8,743 in Geekbench OpenCL, places it below the RX 6600S in every comparison available. Its nearest rivals in the database are all in the 8,700 to 8,900 range, which underscores that it sits in a performance tier that the RX 6600S far exceeds.

For use cases, the RX 6600S is suited to modern workloads that leverage DirectX 12 Ultimate features, including ray tracing and variable rate shading. Its 4 GB GDDR6 memory and 224.0 GB/s bandwidth can handle modern game textures at moderate resolutions. The GTX 460 v2, with 1 GB GDDR5 and 96.19 GB/s bandwidth, is limited to older titles or low-detail settings. Its lack of Vulkan support and older DirectX 12 (11_0) feature level restrict it to legacy applications.

The RX 6600S also wins on portability: it is an IGP-class part with no power connectors, designed for laptops or compact systems. The GTX 460 v2 is a dual-slot desktop card with external power requirements and a 450 W PSU recommendation. For any scenario where size, power, or thermals matter, the AMD part is the clear choice.
