AMD Radeon RX 6600 LE vs Intel Arc Pro B370 Comparison

AMD Radeon RX 6600 LE is a discrete graphics card built on the RDNA 2.0 architecture, using the Navi 23 chip on a 7 nm TSMC process. Intel Arc Pro B370 is an integrated graphics processor based on the Xe3-LPG architecture, using the Panther Lake chip on Intel's 3 nm process. The two products occupy different segments of the graphics hardware spectrum, and their recorded benchmark data reflects that distinction.

Where Each One Wins

The AMD Radeon RX 6600 LE delivers all of its measurable performance in dedicated benchmark tests. The database contains two benchmark results for this card: a Geekbench OpenCL score of 69,229 and a Geekbench Vulkan score of 72,428. The average benchmark score across these two tests is 70,829. This places the RX 6600 LE at the 91st percentile among all GPUs in the database, meaning it outperforms roughly nine out of ten recorded graphics processors.

The Intel Arc Pro B370 has no recorded benchmark scores in the database. Its average benchmark score is listed as zero, and its percentile rank sits at 50, which is the median position among all GPUs. Without any recorded test results, the Arc Pro B370 cannot claim a win in any benchmark category. The data shows that the RX 6600 LE wins every available comparison by default, since the Arc Pro B370 has no scores to compare.

Looking at the use-case split, the RX 6600 LE shows a slight advantage in Vulkan workloads over OpenCL. The Vulkan score of 72,428 is 4.6% higher than the OpenCL score of 69,229. This indicates the card handles Vulkan API tasks with a modest edge in efficiency. For the Arc Pro B370, no such comparison is possible because no benchmark data exists.

The nearest rivals for the RX 6600 LE provide additional context for its performance tier. The AMD Radeon RX 6650M averages 71,768 points, which is 1.3% above the RX 6600 LE. The NVIDIA RTX A3000 Mobile averages 70,140 points, just 1% higher. The NVIDIA Quadro P6000 averages 69,986 points, 1.2% higher than the RX 6600 LE. The AMD Radeon Pro WX 8200 averages 69,870 points, 1.4% lower than the RX 6600 LE. These deltas show the RX 6600 LE sits in a tightly contested performance band where the closest competitors are within a couple of percentage points.

Architecture Differences

The architectural split between these two products is substantial. The RX 6600 LE uses the Navi 23 chip with RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. The chip contains 11,060 million transistors on a 237 mm² die, resulting in a transistor density of 46.7 million transistors per square millimeter. The Arc Pro B370 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel. The transistor count and die size for the Panther Lake chip are listed as unknown in the database, so no direct density comparison is possible.

The RX 6600 LE has 1,792 shading units, 112 texture mapping units, and 64 raster output units. It also includes 28 ray tracing cores. The Arc Pro B370 has 1,280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. In every unit count, the RX 6600 LE holds a numerical advantage: 40% more shading units, 180% more TMUs, 220% more ROPs, and 180% more ray tracing cores.

Memory architecture diverges sharply. The RX 6600 LE carries 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The memory clock runs at 1750 MHz, which translates to 14 Gbps effective. The Arc Pro B370 uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent. This means the Intel part relies on the host system's memory rather than dedicated VRAM, which typically introduces latency and bandwidth constraints that dedicated memory avoids.

Clock behavior differs as well. The RX 6600 LE has a base clock of 1626 MHz, a boost clock of 2495 MHz, and a game clock of 2045 MHz. The Arc Pro B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed. The RX 6600 LE boosts 4% higher than the Arc Pro B370, while its base clock runs over five times higher.

Compute throughput follows the same pattern. The RX 6600 LE delivers 8.942 TFLOPS of FP32 performance and 17.88 TFLOPS of FP16 performance at a 2:1 ratio. The Arc Pro B370 delivers 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16, also at a 2:1 ratio. The RX 6600 LE is 45.5% ahead in FP32 and 45.5% ahead in FP16. Pixel fill rate for the RX 6600 LE is 159.7 GPixel/s versus 48.00 GPixel/s for the Arc Pro B370, a gap of 233%. Texture fill rate is 279.4 GTexel/s versus 96.00 GTexel/s, a gap of 191%.

Both products support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 6600 LE was released on December 7, 2023, while the Arc Pro B370 has a release date of January 26, 2026. The RX 6600 LE belongs to the Radeon RX 6000 series with the Navi II generation, and its predecessor is Navi with successor Navi III. The Arc Pro B370 belongs to the Arc Graphics-WM (Panther Lake) generation, with predecessor HD Graphics-WM and no successor listed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the RX 6600 LE and the Arc Pro B370. The head-to-head benchmark array is empty, and the win counts for both products are zero. This means no direct comparison scores exist in the recorded data.

However, the individual benchmark results for the RX 6600 LE provide the only measurable performance data. The Geekbench OpenCL test produced a score of 69,229, and the Geekbench Vulkan test produced a score of 72,428. These two results average to 70,829. The Arc Pro B370 has no benchmark entries, so its performance cannot be quantified from the database.

The nearest rival data for the RX 6600 LE shows how it performs against other GPUs in the database. The AMD Radeon RX 6650M scores 71,768, which is 1.3% higher than the RX 6600 LE. The NVIDIA RTX A3000 Mobile scores 70,140, which is 1% higher. The NVIDIA Quadro P6000 scores 69,986, which is 1.2% higher. The AMD Radeon Pro WX 8200 scores 69,870, which is 1.4% lower. These rival comparisons show the RX 6600 LE performs within a narrow band around 70,000 points, with all four nearest rivals within 1.4% of its average score.

The Vulkan score of 72,428 stands 4.6% above the OpenCL score of 69,229 for the RX 6600 LE. This suggests the card responds favorably to the Vulkan API in synthetic workloads. The Arc Pro B370 has no such data, so no API-specific behavior can be assessed.

The specification gaps between the two products are large in every compute category. The RX 6600 LE delivers 45.5% more FP32 throughput than the Arc Pro B370. Its pixel fill rate is 233% higher, and its texture fill rate is 191% higher. The shading unit advantage of 40% translates directly into the compute throughput advantage, since both architectures use a scalar shader model. The memory bandwidth situation is not comparable because the Arc Pro B370 depends on system memory, while the RX 6600 LE has dedicated GDDR6 with a fixed 224.0 GB/s figure.

The RX 6600 LE also holds advantages in clock speeds, with a boost clock of 2495 MHz versus 2400 MHz for the Arc Pro B370. The base clock difference is more pronounced: 1626 MHz versus 300 MHz. The RX 6600 LE has a game clock of 2045 MHz, which the Arc Pro B370 lacks entirely.

In the database context, the RX 6600 LE ranks at the 91st percentile among all GPUs, while the Arc Pro B370 sits at the 50th percentile. This percentile gap reflects the absence of benchmark scores for the Intel part rather than any measured performance deficit. The RX 6600 LE's average score of 70,829 places it in a competitive tier with mobile workstation GPUs and professional cards from NVIDIA, as shown by its nearest rivals.

The production status for both products is listed as active. The RX 6600 LE has a release date in December 2023, while the Arc Pro B370 has a release date in January 2026. The RX 6600 LE is a discrete card with its own power connector and cooling solution, while the Arc Pro B370 is an integrated processor with no power connector and no physical dimensions.

Given the available data, the RX 6600 LE is the only product with measurable benchmark performance. The Arc Pro B370 lacks recorded scores, leaving its actual performance outside the scope of the database. The specification differences confirm that these are different classes of hardware: one dedicated discrete GPU, one integrated graphics solution.
