AMD Radeon RX 6600 LE vs Intel Arc G3 Comparison

Where Each One Wins

The benchmark data presents a clear separation between these two graphics solutions. The AMD Radeon RX 6600 LE is a discrete, actively produced desktop graphics card with recorded performance measurements. The Intel Arc G3 is an integrated graphics processor (IGP) that, at the time of data collection, has no recorded benchmark scores. The database shows the RX 6600 LE with two completed tests: Geekbench OpenCL at 69,229 points and Geekbench Vulkan at 72,428 points. The Arc G3 has an empty benchmark array, which means the database has no measured performance data for it.

The RX 6600 LE holds the percentile advantage as well. It sits at the 91st percentile among all GPUs in the database, while the Arc G3 sits at the 50th percentile. That percentile gap indicates that the RX 6600 LE outperforms roughly 41 percent more of the database's GPU population than the Arc G3 does, based on recorded scores. The Arc G3's average benchmark score is listed as 0, with no rivals recorded, whereas the RX 6600 LE has an average score of 70,829.

In terms of compute resources, the RX 6600 LE delivers 8.942 TFLOPS of FP32 performance, 17.88 TFLOPS of FP16 performance, 279.4 GTexel/s of texture rate, and 159.7 GPixel/s of pixel rate. The Arc G3 delivers 6.144 TFLOPS FP32, 12.29 TFLOPS FP16, 96.00 GTexel/s, and 48.00 GPixel/s. For every one of these throughput metrics, the RX 6600 LE is ahead. The texture rate gap is particularly wide: the RX 6600 LE is roughly 2.9 times the Arc G3's texture throughput. The pixel rate gap is even larger, at roughly 3.3 times.

The Arc G3 wins in the specific category of power efficiency per the recorded TDP figures. Its TDP is 25 W, while the RX 6600 LE is rated at 132 W. That is a 107 W difference in favor of the Intel part. The Arc G3 also uses no power connectors and is an IGP, meaning it draws from the host platform rather than requiring a dedicated supply. The RX 6600 LE requires a single 8-pin connector and a 300 W suggested power supply. The Arc G3 is built on a 3 nm Intel process, while the RX 6600 LE uses a 7 nm TSMC process, so the process node advantage also belongs to the Intel part.

The Verdict

The data supports a straightforward choice for users who need measured graphics performance: the AMD Radeon RX 6600 LE. It has recorded benchmark results in both OpenCL and Vulkan, a 91st percentile ranking, and an average benchmark score of 70,829. The Intel Arc G3 has no recorded benchmarks, an average score of 0, and a 50th percentile ranking. Any workload that relies on compute throughput, texture processing, or pixel fill will favor the AMD part based on the recorded specifications.

The Intel Arc G3 is the appropriate selection for systems where power draw is the dominant constraint. Its 25 W TDP is dramatically lower than the RX 6600 LE's 132 W. It is an IGP with no slot width, no power connectors, and no suggested PSU, so it fits into portable or low-power platforms without additional cooling or power delivery hardware. Its memory is system shared, which removes the need for dedicated VRAM and simplifies the overall system design.

For gaming and general graphics workloads, the RX 6600 LE's 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth gives it a dedicated memory subsystem. The Arc G3 relies on system shared memory with bandwidth described as system dependent, which introduces variability based on the host platform. The RX 6600 LE also has more shading units (1,792 versus 1,280), more texture mapping units (112 versus 40), more raster operations units (64 versus 20), and more ray tracing cores (28 versus 10).

The verdict from the database is not ambiguous: the RX 6600 LE is the only one of the two with measured performance data, and it dominates the throughput metrics. The Arc G3 is the only one of the two that qualifies as a low-power integrated solution with a 3 nm process, but its performance is unmeasured in this database.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries between the RX 6600 LE and the Arc G3 in the database. The headToHeadBenchmarks array is empty, and neither winsA nor winsB registers a value. The comparison must therefore rely on the individual recorded scores and specifications.

The RX 6600 LE's Geekbench OpenCL score is 69,229. Its Geekbench Vulkan score is 72,428. The Vulkan result is 3,199 points higher than the OpenCL result, indicating a 4.6 percent advantage for the Vulkan API on this card. The average of the two scores is 70,829, which is the card's avgBenchmarkScore.

Relative to its nearest rivals in the database, the RX 6600 LE sits within a tight cluster. The NVIDIA RTX A3000 Mobile averages 70,140, which is 1 percent below the RX 6600 LE. The NVIDIA Quadro P6000 averages 69,986, which is 1.2 percent below. The AMD Radeon Pro WX 8200 averages 69,870, which is 1.4 percent below. The only rival that scores higher is the AMD Radeon RX 6650M at 71,768, which is 1.3 percent above the RX 6600 LE. This means the RX 6600 LE is competitive with mobile and workstation GPUs in its immediate performance neighborhood, with deltas ranging from 1.4 percent behind to 1.3 percent ahead.

The Arc G3 has no nearest rivals recorded and no average score, so it cannot be positioned within any competitive performance band. Its only ranking data is the 50th percentile, which places it at the median of the database's GPU population, but without benchmark scores, that percentile appears to be derived from specification-based classification rather than measured results.

The largest specification-based wins for the RX 6600 LE are in texture rate and pixel rate. The texture rate difference is 279.4 GTexel/s versus 96.00 GTexel/s, a 183.4 GTexel/s gap. The pixel rate difference is 159.7 GPixel/s versus 48.00 GPixel/s, a 111.7 GPixel/s gap. The FP32 throughput gap is 2.798 TFLOPS, and the FP16 gap is 5.59 TFLOPS.

Architecture Differences

The two GPUs come from different manufacturers and different architectural generations. The AMD Radeon RX 6600 LE uses the Navi 23 chip based on RDNA 2.0 architecture, belonging to the Navi II generation of the RX 6000 series. The Intel Arc G3 uses the Panther Lake chip based on Xe3-LPG architecture, belonging to the Arc Graphics-M generation for Panther Lake.

Process technology differs substantially. The RX 6600 LE is fabricated on a 7 nm process at TSMC, with 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million transistors per square millimeter. The Arc G3 is fabricated on a 3 nm process at Intel, with its transistor count and die size listed as unknown in the database.

Compute unit counts diverge across every major category. The RX 6600 LE has 1,792 shading units, 112 texture mapping units, 64 raster operations units, and 28 ray tracing cores. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 raster operations units, and 10 ray tracing cores. Neither part lists tensor cores.

Clock behavior is also different. The RX 6600 LE has a base clock of 1626 MHz, a boost clock of 2495 MHz, and a game clock of 2045 MHz. Its memory clock is 1750 MHz with 14 Gbps effective data rate. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed and memory clock described as system shared.

Memory architecture is a fundamental split. The RX 6600 LE uses dedicated 8 GB GDDR6 with a 128-bit bus and fixed 224.0 GB/s bandwidth. The Arc G3 uses system shared memory with system shared bus width and system dependent bandwidth. This means the Intel part's memory performance cannot be stated as a fixed number.

Power delivery and physical design differ completely. The RX 6600 LE is a dual-slot card measuring 190 mm in length, 110 mm in height, and 40 mm in width, with one 8-pin power connector and a 300 W suggested power supply. The Arc G3 is an IGP with no slot width, no dimensions listed, no power connectors, and no suggested PSU. Its display outputs are described as portable device dependent.

API support is identical. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release timing is far apart. The RX 6600 LE was released on 2023-12-07. The Arc G3 is dated 2026-05-31 in the database, which places it more than two years later in the product timeline. The RX 6600 LE has a listed predecessor (Navi) and successor (Navi III), while the Arc G3 has neither. Production status for both is active.
