Intel Arc B370 vs NVIDIA GeForce RTX 5090 SE Comparison

The Verdict

The database comparison between the Intel Arc B370 and the NVIDIA GeForce RTX 5090 SE reveals two products engineered for entirely different purposes. The Arc B370 is an integrated graphics processor within Intel's Panther Lake mobile platform, consuming just 25 W and sharing system memory. The RTX 5090 SE is a discrete flagship-class GPU with a 500 W TDP, 24 GB of dedicated GDDR7 memory, and a 384-bit memory bus. The recorded benchmark data shows the Arc B370 scoring 1184 in the 3DMark Steel Nomad DX12 test, placing it in the 5th percentile of all GPUs. The RTX 5090 SE has no recorded benchmark scores in the database, but its specifications indicate a fundamentally different performance class. The Arc B370 is positioned for portable devices where power efficiency and integration matter, while the RTX 5090 SE targets high-end desktop systems requiring maximum throughput.

Architecture Differences

The Intel Arc B370 uses the Xe3-LPG architecture built on Intel's 3 nm process node, featuring the Panther Lake chip. It belongs to the Arc Graphics-M (Panther Lake) generation. The RTX 5090 SE uses the Blackwell 2.0 architecture on TSMC's 5 nm process, with the GB202 chip and belongs to the GeForce 50-series.

The transistor counts illustrate the scale difference. The RTX 5090 SE packs 92,200 million transistors on a 750 mm² die with a density of 122.9M per mm². The Arc B370's transistor count and die size are listed as unknown in the database, but its integrated nature suggests a much smaller footprint. The Arc B370 operates with a base clock of 300 MHz and a boost clock of 2400 MHz, while the RTX 5090 SE runs at 1740 MHz base and 2377 MHz boost.

Memory architecture diverges sharply. The Arc B370 uses system shared memory, meaning its memory size, type, and bus width are all system dependent. The RTX 5090 SE has 24 GB of GDDR7 memory on a 384-bit bus with 1.34 TB/s bandwidth. The RTX 5090 SE's memory clock is listed at 1750 MHz with 28 Gbps effective speed.

The compute resources show a massive disparity. The Arc B370 has 1280 shading units, 40 texture mapping units, 20 raster operation units, 10 ray tracing cores, and no dedicated tensor cores. The RTX 5090 SE has 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5090 SE uses a PCIe 5.0 x16 bus interface, while the Arc B370 uses an integrated IGP interface. The RTX 5090 SE requires a 1x 16-pin power connector and a suggested 900 W PSU, whereas the Arc B370 requires no power connectors.

Where Each One Wins

The Arc B370 wins in power efficiency and integration. Its 25 W TDP allows it to function without external power connectors, and its IGP bus interface means it is embedded directly into the processor package. The database lists its display outputs as "Portable Device Dependent," confirming its target use case in laptops and portable systems. The Arc B370's 3 nm process node represents a newer manufacturing technology compared to the RTX 5090 SE's 5 nm node, which contributes to its low power draw.

The RTX 5090 SE wins in almost every raw performance metric. Its FP32 compute of 66.94 TFLOPS dwarfs the Arc B370's 6.144 TFLOPS. The pixel rate of 380.3 GPixel/s versus 48.00 GPixel/s shows a 7.9x advantage in rasterization throughput. The texture rate of 1,045.9 GTexel/s versus 96.00 GTexel/s represents a 10.9x advantage. The RTX 5090 SE's FP16 performance of 66.94 TFLOPS at 1:1 ratio contrasts with the Arc B370's 12.29 TFLOPS at 2:1 ratio, indicating the NVIDIA GPU can maintain full throughput for FP16 workloads.

The RTX 5090 SE supports dedicated tensor cores, which the Arc B370 lacks entirely. The 440 tensor cores on the NVIDIA GPU enable AI-accelerated workloads that the Intel integrated solution cannot match. The RTX 5090 SE also provides 110 RT cores versus 10 on the Arc B370, offering 11x the ray tracing hardware.
