The Verdict

The recorded data separates these two GPUs into distinct performance classes. The RX 6600 LE shows a 91st percentile ranking among all GPUs, with an average benchmark score of 70829. Its nearest rivals in the database include the AMD Radeon RX 6650M at 71768 (1.3% ahead), the NVIDIA RTX A3000 Mobile at 70140 (1% behind), and the NVIDIA Quadro P6000 at 69986 (1.2% behind). This cluster of scores indicates the RX 6600 LE performs within a tight band of mobile and professional workstation GPUs.

The Arc A310E has no benchmark entries, making direct performance comparison impossible from the database. Its 50th percentile ranking reflects the median position of all GPUs, but without measured scores, that percentile cannot be tied to actual compute results. The RX 6600 LE delivers 2.9 times the FP32 throughput of the Arc A310E (8.942 TFLOPS versus 3.072 TFLOPS) and 1.8 times the memory bandwidth (224.0 GB/s versus 124.0 GB/s). The RX 6600 LE also carries 8 GB of GDDR6 memory compared to 4 GB on the Arc A310E.

For users requiring sustained compute performance, the RX 6600 LE is the only option with measured results. For applications constrained by power draw and physical space, the Arc A310E uses 57 W less, fits in a single slot, and requires no external power connector. The RX 6600 LE is a dual-slot card with a single 8-pin connector. The Arc A310E, despite its end-of-life status, remains available in active production terms, while the RX 6600 LE shows active production status.

Where Each One Wins

The RX 6600 LE wins on every metric with a recorded number. Its FP32 compute of 8.942 TFLOPS exceeds the Arc A310E's 3.072 TFLOPS by a factor of 2.9. Texture rate follows the same pattern: 279.4 GTexel/s versus 64.00 GTexel/s, a 4.4 times advantage. Pixel rate is 159.7 GPixel/s against 32.00 GPixel/s, a 5.0 times margin. The RX 6600 LE has 1792 shading units, 112 texture mapping units, and 64 render output units; the Arc A310E has 768 shading units, 32 TMUs, and 16 ROPs. Ray tracing cores also differ: 28 on the RX 6600 LE versus 6 on the Arc A310E.

Memory capacity favors the RX 6600 LE with 8 GB GDDR6 on a 128-bit bus, versus 4 GB GDDR6 on a 64-bit bus. Bandwidth of 224.0 GB/s versus 124.0 GB/s means the RX 6600 LE can feed its shader array more effectively. Clock speeds show the Arc A310E runs a constant 2000 MHz base and boost, while the RX 6600 LE has a 1626 MHz base, 2045 MHz game clock, and 2495 MHz boost. The higher boost clock on the RX 6600 LE contributes to its compute advantage.

The Arc A310E wins in power efficiency and physical footprint. Its 75 W TDP versus 132 W represents a 43% reduction. The single-slot design at 20 mm width contrasts with the RX 6600 LE's 40 mm dual-slot width. The Arc A310E measures 168 mm in length and 69 mm in height, while the RX 6600 LE measures 190 mm by 110 mm. No power connector on the Arc A310E simplifies installation, whereas the RX 6600 LE needs a 1x 8-pin connector. The suggested PSU for the Arc A310E is 250 W versus 300 W for the RX 6600 LE.

Architecture Differences

The RX 6600 LE uses the Navi 23 chip manufactured on a 7 nm process at TSMC, containing 11,060 million transistors on a 237 mm² die. Transistor density is 46.7M per mm². The architecture is RDNA 2.0, part of the Navi II generation (RX 6000 series). The Arc A310E uses the DG2-128 chip on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die. Transistor density is 45.9M per mm². The architecture is Xe-HPG, part of the Alchemist generation (Arc 3).

The node difference is one generation apart: 7 nm versus 6 nm. Despite the smaller node, the Arc A310E has fewer transistors (7,200 million versus 11,060 million) and a smaller die (157 mm² versus 237 mm²). Transistor density is nearly identical, with the RX 6600 LE at 46.7M per mm² and the Arc A310E at 45.9M per mm². This suggests the RX 6600 LE packs more logic per area despite the older node.

Memory subsystems differ fundamentally. The RX 6600 LE uses GDDR6 at 1750 MHz with 14 Gbps effective data rate, producing 224.0 GB/s across a 128-bit bus. The Arc A310E uses GDDR6 at 1937 MHz with 15.5 Gbps effective, producing 124.0 GB/s across a 64-bit bus. The Arc A310E has a higher memory clock but half the bus width, resulting in 45% less bandwidth. FP16 compute on the RX 6600 LE is 17.88 TFLOPS (2:1 ratio), versus 6.144 TFLOPS on the Arc A310E.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the RX 6600 LE provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Arc A310E provides 4x mini-DisplayPort 2.0. Both use PCIe 4.0 x8 interfaces. The RX 6600 LE has a game clock of 2045 MHz, a feature absent in the Arc A310E's specifications. The Arc A310E's predecessor is Xe Graphics, and its successor is Battlemage; the RX 6600 LE's predecessor is Navi and successor is Navi III.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark entries between these two GPUs, and the Arc A310E has zero recorded benchmark scores. The only measurable comparison comes from the RX 6600 LE's own benchmarks and its nearest rivals. In Geekbench OpenCL, the RX 6600 LE scores 69229; in Geekbench Vulkan, it scores 72428. The average of these two is 70829, which aligns closely with the nearest rival scores.

The RX 6600 LE's nearest rival, the AMD Radeon RX 6650M, averages 71768, which is 1.3% higher. The NVIDIA RTX A3000 Mobile averages 70140, 1% lower. The NVIDIA Quadro P6000 averages 69986, 1.2% lower. The AMD Radeon Pro WX 8200 averages 69870, 1.4% lower. These four rivals bracket the RX 6600 LE within a 2.7% total spread, indicating the RX 6600 LE sits in a competitive performance tier.

Against the Arc A310E, the RX 6600 LE's compute advantage is decisive in raw throughput. The FP32 figure of 8.942 TFLOPS versus 3.072 TFLOPS means the RX 6600 LE processes nearly three times as many floating-point operations per second. Texture rate of 279.4 GTexel/s versus 64.00 GTexel/s gives the RX 6600 LE a 4.4 times advantage in texturing workloads. Pixel rate of 159.7 GPixel/s versus 32.00 GPixel/s gives a 5.0 times edge in fill-rate-bound scenarios.

The Arc A310E does not close the gap in any compute metric. Its 768 shading units are 43% of the RX 6600 LE's 1792 units. Its 32 TMUs are 29% of the RX 6600 LE's 112 TMUs. Its 16 ROPs are 25% of the RX 6600 LE's 64 ROPs. Ray tracing cores number 6 versus 28, a 21% ratio. The memory bandwidth deficit of 124.0 GB/s versus 224.0 GB/s means the Arc A310E cannot sustain data delivery comparable to the RX 6600 LE.

Clock behavior differs meaningfully. The Arc A310E holds a flat 2000 MHz base and boost, with no game clock specified. The RX 6600 LE ramps from 1626 MHz base to 2045 MHz game and 2495 MHz boost. The 2495 MHz boost is 25% higher than the Arc A310E's boost, contributing to the RX 6600 LE's higher peak throughput. The RX 6600 LE also has a higher pixel rate per ROP: 159.7 GPixel/s divided by 64 ROPs equals 2.5 GPixel/s per ROP, versus 32.00 GPixel/s divided by 16 ROPs equals 2.0 GPixel/s per ROP on the Arc A310E.

Both GPUs support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software written to those APIs can run on either card, but the RX 6600 LE's hardware resources will execute those workloads faster. The Arc A310E's advantage lies in its 43% lower TDP, single-slot form factor, and lack of a power connector, which suits compact systems. The RX 6600 LE's advantage is measured performance, with a 91st percentile ranking and benchmark scores that place it among established rivals like the RTX A3000 Mobile and Quadro P6000.
