Architecture Differences

The NVIDIA A10G is built on the GA102 chip using the Ampere architecture, fabricated on an 8 nm Samsung process. It contains 28,300 million transistors on a 628 mm² die, yielding a density of 45.1 million transistors per square millimeter. The AMD Radeon RX 6600 LE uses the Navi 23 chip with RDNA 2.0 architecture, manufactured on TSMC’s 7 nm node. This smaller die measures 237 mm² and houses 11,060 million transistors, with a slightly higher density of 46.7 million per mm².

Compute resources differ dramatically. The A10G features 9,216 shading units, 288 texture mapping units, 96 ROPs, 72 RT cores, and 288 tensor cores. The RX 6600 LE has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, with no tensor cores listed. This structural disparity explains the significant FP32 throughput gap: the A10G delivers 31.52 TFLOPS, while the RX 6600 LE achieves 8.942 TFLOPS. In FP16, the A10G maintains a 1:1 ratio at 31.52 TFLOPS, whereas the RX 6600 LE uses a 2:1 ratio to reach 17.88 TFLOPS.

Memory subsystems also diverge. The A10G carries 24 GB of GDDR6 on a 384-bit bus, providing 600.2 GB/s of bandwidth. The RX 6600 LE has 8 GB of GDDR6 on a 128-bit bus, with 224.0 GB/s. Clock behavior differs as well: the A10G runs a base of 1320 MHz and boost of 1710 MHz, while the RX 6600 LE starts at 1626 MHz base, 2495 MHz boost, with a game clock of 2045 MHz. Memory clocks are 1563 MHz (12.5 Gbps effective) for the A10G and 1750 MHz (14 Gbps effective) for the RX 6600 LE.

Physical and power characteristics are not identical. The A10G is a single-slot card, 267 mm long and 112 mm high, with a 150 W TDP and an 8-pin EPS connector. The RX 6600 LE is dual-slot, 190 mm long, 110 mm high, and 40 mm wide, with a 132 W TDP and a single 8-pin connector. The A10G has no display outputs, while the RX 6600 LE includes 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both use PCIe 4.0, but the A10G runs x16 while the RX 6600 LE runs x8.

Head-to-Head Benchmarks

The database records two head-to-head tests, and the NVIDIA A10G wins both by a wide margin. In Geekbench OpenCL, the A10G posts 158,063 points against the RX 6600 LE’s 69,229, a delta of 128.3%. This means the A10G more than doubles the RX 6600 LE’s raw compute score. In Geekbench Vulkan, the A10G scores 145,863 versus 72,428, a delta of 101.4%, again exceeding double the rival’s result.

These margins align with the broader benchmark averages. The A10G’s average of 151,963 is 114.5% higher than the RX 6600 LE’s 70,829. To contextualize, the A10G sits within 1.1% of the Tesla V100 and 6.5% below the A100, while the RX 6600 LE is nearly tied with the RTX A3000 Mobile (1% delta) and the Quadro P6000 (1.2% delta). The RX 6600 LE’s closest competitor, the RX 6650M, beats it by only 1.3%, so the RX 6600 LE is firmly in the mid-range compute tier.

The A10G’s strength comes from its massive shading and tensor core count, plus its 24 GB memory pool. The RX 6600 LE’s higher boost clock (2495 MHz versus 1710 MHz) does not compensate for the 5x difference in shading units. Even in Vulkan, which often favors efficient driver overhead, the A10G maintains a 101.4% lead. The data shows no test where the RX 6600 LE closes the gap below 100%.

It is worth remembering the RX 6600 LE’s pixel rate (159.7 GPixel/s) is close to the A10G’s (164.2 GPixel/s), and its texture rate (279.4 GTexel/s) is more than half of the A10G’s (492.5 GTexel/s). However, these fillrate metrics do not translate into competitive Geekbench scores, likely due to the A10G’s superior memory bandwidth and compute throughput.

The Verdict

The recorded data points to a clear split in purpose. The NVIDIA A10G is a server-oriented accelerator with no display outputs, designed for compute workloads that benefit from 24 GB of memory, tensor cores, and 31.52 TFLOPS of FP32 performance. Its 97th percentile rank and proximity to the A100 and Tesla V100 confirm that it belongs in the high-end compute segment.

The AMD Radeon RX 6600 LE, by contrast, is an active consumer RDNA 2 part with display outputs, a dual-slot cooler, and a 132 W TDP. Its 91st percentile rank and near-tie with mobile and workstation GPUs like the RTX A3000 Mobile and Quadro P6000 indicate a mid-range profile. It wins no head-to-head benchmarks against the A10G, but it is not designed to compete in that class.

For buyers needing raw compute, large memory capacity, and server integration, the A10G is the only choice based on the benchmarks. For those needing a compact, display-capable card with lower power draw, the RX 6600 LE is the relevant option. The database shows a 128.3% and 101.4% lead for the A10G in the two recorded tests, and no scenario where the RX 6600 LE overtakes it.

The production status reinforces this: the A10G is end-of-life, while the RX 6600 LE is still active. This suggests the A10G is a legacy server part, whereas the RX 6600 LE is a current retail product. The predecessor and successor fields also differ: the A10G follows Tesla Turing and precedes Server Ada, while the RX 6600 LE follows Navi and precedes Navi III.
