Intel Arc Pro B370 vs NVIDIA GeForce RTX 5080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries for the Intel Arc Pro B370 and the NVIDIA GeForce RTX 5080 Mobile. The Intel part has no benchmark scores in the database, while the NVIDIA adapter has a full suite of results across DirectX, OpenCL, Vulkan, and compute workloads. The RTX 5080 Mobile's average benchmark score of 38,349 places it at the 81st percentile among all GPUs, indicating strong overall performance relative to the broader database population. Its nearest rivals include the NVIDIA GeForce MX570 with an average score of 38,299 and a delta of 0.1%, the NVIDIA GeForce RTX 4080 Mobile at 38,135 with a 0.6% delta, the NVIDIA GeForce MX570 A at 38,691 with a -0.9% delta, and the AMD Radeon Pro 580X at 38,706 with a -0.9% delta. These close margins, all within roughly one percent, show that the RTX 5080 Mobile clusters tightly with these competitors in aggregate scoring.

The most dominant result for the RTX 5080 Mobile comes from Geekbench Vulkan, where it scores 169,754, and Geekbench OpenCL, where it scores 166,986. These two results lead the benchmark suite by a wide margin over the DirectX entries. In PassMark testing, the G3D score of 27,711 is the strongest legacy graphics result, while the GPU compute score of 12,134 shows solid compute throughput. The DirectX 9 score of 314, the DirectX 11 score of 253, and the DirectX 10 score of 171 represent older API workloads. The DirectX 12 score of 116 is the lowest graphics test result, and the G2D score of 1,095 covers 2D operations. Since the Intel Arc Pro B370 has no recorded benchmark scores, no direct wins can be attributed to it in this comparison. The data simply confirms that the NVIDIA part has measurable results, while the Intel integrated graphics adapter currently has none.

Architecture Differences

The Intel Arc Pro B370 is built on the Panther Lake chip with the Xe3-LPG architecture, produced on Intel's 3 nm process node. The NVIDIA GeForce RTX 5080 Mobile uses the GB203 chip with the Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. The Intel part is listed as part of the Arc Graphics-WM generation for Panther Lake, while the NVIDIA part belongs to the GeForce 50 Mobile generation. The Intel processor has a base clock of 300 MHz and a boost clock of 2400 MHz, whereas the NVIDIA processor runs at a base clock of 975 MHz and a boost clock of 1500 MHz. The Intel adapter operates within a 25 W TDP, while the NVIDIA adapter is rated at 80 W TDP.

The NVIDIA chip contains 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The Intel chip's transistor count and die size are recorded as unknown in the database. The RTX 5080 Mobile supports PCIe 5.0 x16 as its bus interface, while the Intel part uses an integrated graphics processor interface with no bus interface specification beyond IGP. Both adapters are marked as IGP slot width, meaning they are not discrete add-in cards. Neither uses external power connectors, and both have display outputs listed as portable device dependent.

The Intel Arc Pro B370 features 1,280 shading units, 40 texture mapping units, 20 raster operation units, and 10 ray tracing cores. The NVIDIA GeForce RTX 5080 Mobile features 7,680 shading units, 240 texture mapping units, 96 raster operation units, 60 ray tracing cores, and 240 tensor cores. The Intel part has no tensor core listing in the database. The NVIDIA part's shading unit count is six times that of the Intel part, while its texture mapping units are also six times higher and its raster operation units are nearly five times higher. The ray tracing core count is six times higher on the NVIDIA side.

Where Each One Wins

The NVIDIA GeForce RTX 5080 Mobile wins on every measurable axis in the database because the Intel Arc Pro B370 has no benchmark results to compare. The RTX 5080 Mobile's 81st percentile ranking versus all GPUs indicates it outperforms the vast majority of recorded adapters. Its compute capabilities are demonstrated by the Geekbench OpenCL score of 166,986 and the PassMark GPU compute score of 12,134. The Vulkan result of 169,754 reinforces strength in modern low-level graphics APIs. Legacy DirectX performance is present but uneven, with the DirectX 9 score of 314 exceeding the DirectX 11 score of 253, the DirectX 10 score of 171, and the DirectX 12 score of 116.

In terms of raw throughput, the RTX 5080 Mobile delivers 23.04 TFLOPS of FP32 performance and 23.04 TFLOPS of FP16 with a 1:1 ratio. Pixel rate is 144.0 GPixel/s and texture rate is 360.0 GTexel/s. The Intel Arc Pro B370 delivers 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16 with a 2:1 ratio. Its pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s. The NVIDIA part is ahead in every throughput figure, roughly 3.75 times in FP32, 1.87 times in FP16, 3 times in pixel rate, and 3.75 times in texture rate. The Intel part's higher boost clock of 2400 MHz versus 1500 MHz does not compensate for the much lower execution resource count.

Memory is another decisive area. The RTX 5080 Mobile uses 16 GB of GDDR7 on a 256 bit bus with 896.0 GB/s of bandwidth. The Intel Arc Pro B370 uses system shared memory with a system dependent bandwidth, making its memory performance entirely dependent on the host platform. The NVIDIA part's dedicated graphics memory with a 256 bit interface allows for predictable bandwidth, while the Intel part relies on shared system resources. The RTX 5080 Mobile has no launch MSRP recorded in the database. The Intel part also has no launch MSRP recorded.
