Architecture Differences

The AMD Radeon RX 7900 GRE belongs to the Radeon RX 7000 series and is built on the RDNA 3.0 architecture, specifically using the Navi 31 chip with the codename Plum Bonito. It is manufactured on a 5 nm process at TSMC, integrating 57,700 million transistors on a 529 mm² die, which yields a transistor density of 109.1M per mm². The GPU is part of the Navi III generation and follows the Radeon RX 7000 series lineage, with its predecessor being Navi II and its successor being Navi IV.

The Intel Arc B370, by contrast, uses the Xe3-LPG architecture with the Panther Lake chip and belongs to the Arc Graphics-M (Panther Lake) generation. It is built on a 3 nm process at Intel, but the transistor count, die size, and transistor density are listed as unknown. The Intel part is an integrated graphics processor (IGP) with a base clock of 300 MHz and a boost clock of 2400 MHz, whereas the AMD card has a base clock of 1287 MHz and a boost clock of 2245 MHz, along with a game clock of 1880 MHz.

The AMD card features 5120 shading units, 320 texture mapping units (TMUs), 160 raster operation units (ROPs), and 80 ray tracing cores. The Intel Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The memory subsystem differs substantially: the AMD card has 16 GB of GDDR6 memory on a 256-bit bus with a bandwidth of 576.0 GB/s, while the Intel card relies on system-shared memory with system-dependent bandwidth. The AMD card's memory clock is 2250 MHz, translating to 18 Gbps effective.

Power and physical characteristics also diverge. The AMD Radeon RX 7900 GRE has a TDP of 260 W, requires a 600 W suggested power supply, uses dual-slot cooling with 2x 8-pin power connectors, and measures 276 mm in length, 110 mm in height, and 51 mm in width. The Intel Arc B370 has a TDP of 25 W, uses no power connectors, is an IGP with no slot width dimensions, and has no listed dimensions. The AMD card interfaces via PCIe 4.0 x16, while the Intel card uses an IGP bus interface. Display outputs also differ: the AMD card offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, whereas the Intel card's outputs are portable device dependent.

The Verdict

The benchmark data shows a decisive performance gap favoring the AMD Radeon RX 7900 GRE. In the only head-to-head benchmark recorded, the 3DMark Steel Nomad DX12 test, the AMD card scores 4814 against the Intel Arc B370's 1184, a delta of 306.6% in AMD's favor. The AMD card also holds a 77th percentile ranking among all GPUs, while the Intel card sits at the 5th percentile.

For users seeking discrete desktop performance with high compute throughput, the data points to the AMD Radeon RX 7900 GRE. Its average benchmark score of 32456 compares to the Intel part's 1184, and the AMD card's nearest rivals in the database, such as the AMD FirePro S10000 at 32388 (0.2% delta) and the AMD Radeon Pro 570X at 32176 (0.9% delta), all fall within a narrow range of its average score. The Intel Arc B370's nearest rivals, including the ATI Mobility Radeon HD 5570 at 1186 (-0.2% delta) and the AMD FirePro M2000 at 1168 (1.4% delta), indicate it competes in a much lower performance tier.

The Intel Arc B370 is an integrated solution with a 25 W TDP and no power connectors, suited for portable devices or low-power systems where discrete graphics are not required. The AMD card, with its 260 W TDP, dual-slot cooler, and 2x 8-pin power connectors, is a dedicated add-in board for desktop builds. The choice depends on the platform: the AMD card delivers desktop-class performance, while the Intel part serves integrated graphics roles with minimal power draw.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins in the only directly comparable benchmark, the 3DMark Steel Nomad DX12 test, with a score of 4814 versus 1184, a 306.6% advantage. This indicates the AMD card is suited for demanding DX12 workloads, including modern gaming and compute-heavy applications. The AMD card also holds a significant edge in raw compute resources, with 45.98 TFLOPS FP32 performance compared to the Intel card's 6.144 TFLOPS, and a much higher pixel rate of 359.2 GPixel/s versus 48.00 GPixel/s.

The Intel Arc B370 wins in power efficiency and integration. Its 25 W TDP is dramatically lower than the AMD card's 260 W, and it requires no power connectors, making it suitable for portable or low-power systems. The Intel card also has a higher boost clock at 2400 MHz, though this does not translate into higher benchmark scores. Its system-shared memory design eliminates the need for dedicated VRAM, which may simplify system design in integrated contexts.

For use cases, the data positions the AMD Radeon RX 7900 GRE as the choice for discrete desktop graphics where performance is the priority, such as high-end gaming or GPU-accelerated productivity. The Intel Arc B370, with its integrated design and 5th percentile ranking, is aligned with low-power, portable, or embedded scenarios where the AMD card's 260 W TDP and dual-slot cooler would be impractical. The AMD card's active production status and 77th percentile ranking confirm its place in the higher tier of the database, while the Intel card's 5th percentile places it among the lowest-performing recorded GPUs.
