Architecture Differences

The RX 7900 GRE uses the Navi 31 chip under the RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Navi III generation and is manufactured on a 5 nm process at TSMC. The Intel Arc Graphics 1 Xe Mobile uses the Wildcat Lake chip under the Xe3-LPG architecture and belongs to the Arc Graphics-M generation. Intel fabricates this chip on a 3 nm process at its own foundry. The manufacturing process difference is notable: the AMD part uses 5 nm, while the Intel part uses 3 nm.

The RX 7900 GRE is a discrete card with a dual-slot design, a 276 mm length, a 110 mm height, and a 51 mm width. It connects via PCIe 4.0 x16 and requires two 8-pin power connectors. The Intel part is an IGP, meaning integrated graphics processor, with no slot width, no dimensions, no power connectors, and an IGP bus interface. It is designed for portable devices.

Compute resources differ by orders of magnitude. The RX 7900 GRE has 5120 shading units, 320 texture mapping units, 160 ROPs, and 80 ray tracing cores. The Intel Arc Graphics 1 Xe Mobile has 128 shading units, 8 TMUs, 4 ROPs, and 1 ray tracing core. Neither GPU lists tensor cores in the database.

The AMD card runs at a base clock of 1287 MHz, a game clock of 1880 MHz, and a boost clock of 2245 MHz. Its memory clock is 2250 MHz, which translates to 18 Gbps effective. The Intel part has a base clock of 300 MHz and a boost clock of 2300 MHz; it has no game clock listed and its memory clock is marked System Shared.

Pixel and texture rates reinforce the gap. The RX 7900 GRE delivers 359.2 GPixel/s and 718.4 GTexel/s. The Intel part delivers 9.200 GPixel/s and 18.40 GTexel/s. Floating-point performance shows the RX 7900 GRE at 45.98 TFLOPS for FP32 and 91.96 TFLOPS for FP16 (2:1). The Intel part reaches 588.8 GFLOPS for FP32 and 1,177.6 GFLOPS for FP16 (2:1).

The RX 7900 GRE has a release date of 2023-07-26, a predecessor in the Navi II series, and a successor in Navi IV. The Intel part has a release date of 2026-04-15 and lists HD Graphics-M as its predecessor. Both are currently marked as Active in production status.

The Verdict

The data positions these two GPUs for completely different use cases. The AMD Radeon RX 7900 GRE is a discrete desktop graphics card with a 260 W TDP, 16 GB of dedicated GDDR6 memory, and a 57,700 million transistor chip. It is built for high-end gaming and compute workloads where raw throughput matters. Its 77th percentile ranking and an average benchmark score of 32456 place it well above the median.

The Intel Arc Graphics 1 Xe Mobile is a 25 W integrated solution with 128 shading units and system-shared memory. It has no dedicated VRAM, no discrete dimensions, and no power connectors. Its 50th percentile ranking reflects a middle-of-the-pack position, but that ranking comes with an average benchmark score of 0 in the database due to the absence of recorded benchmark entries.

For a user building a desktop system with a dedicated power supply and expecting high frame rates or heavy compute, the RX 7900 GRE is the only viable option based on the recorded specifications. For a thin-and-light portable device where power efficiency and integration matter, the Intel Arc Graphics 1 Xe Mobile fits the IGP form factor. The two do not compete in the same market segment. The RX 7900 GRE has a launch MSRP of 549 USD. The Intel part has no launch MSRP listed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The wins counter shows 0 for both sides. However, the AMD Radeon RX 7900 GRE has a full set of recorded benchmark scores, while the Intel Arc Graphics 1 Xe Mobile has an empty benchmark array.

In 3DMark Steel Nomad DX12, the RX 7900 GRE scores 4814 points. In Geekbench OpenCL, it scores 175758 points. In Geekbench Vulkan, it scores 99850 points. Passmark results for the RX 7900 GRE are as follows: DirectX 10 scores 139, DirectX 11 scores 300, DirectX 12 scores 107, DirectX 9 scores 310, G2D scores 1180, G3D scores 27089, and GPU Compute scores 15016.

The average benchmark score for the RX 7900 GRE is 32456. Its nearest rivals in the database are the AMD FirePro S10000 with an average score of 32388 and a delta of 0.2 percent, the AMD FirePro S9300 X2 with an average score of 32540 and a delta of negative 0.3 percent, the AMD Radeon RX 590 GME with an average score of 32601 and a delta of negative 0.4 percent, and the AMD Radeon Pro 570X with an average score of 32176 and a delta of 0.9 percent. These deltas are all within one percent, indicating that the RX 7900 GRE sits in a tightly packed performance cluster among these rival cards.

The Intel Arc Graphics 1 Xe Mobile has no benchmark scores, no average score, and no nearest rivals in the database. Its percentile of 50 is a positional value, but without measured results, direct numerical comparison is impossible. The recorded data confirms that the RX 7900 GRE delivers 45.98 TFLOPS of FP32 compute, 576.0 GB/s of memory bandwidth, and a 359.2 GPixel/s pixel rate. The Intel part delivers 588.8 GFLOPS of FP32 compute, system-dependent bandwidth, and a 9.200 GPixel/s pixel rate.

The RX 7900 GRE is ahead of the Intel part in every recorded compute metric: roughly 78 times the FP32 throughput, roughly 39 times the pixel rate, roughly 39 times the texture rate, 40 times the shading units, 40 times the TMUs, and 40 times the ROPs. The Intel part has a higher boost clock at 2300 MHz versus 2245 MHz, but that advantage does not compensate for the far smaller execution resource pool. The RX 7900 GRE also carries 80 ray tracing cores versus 1 on the Intel part.

Memory bandwidth is a decisive separator. The RX 7900 GRE sustains 576.0 GB/s from dedicated GDDR6, while the Intel part relies on system-shared memory with system-dependent bandwidth. A discrete GPU with dedicated memory and a 256-bit bus will not behave like an IGP borrowing host memory, regardless of clock speeds. The RX 7900 GRE also consumes 260 W versus 25 W, a 10.4 times difference in power draw, which explains the performance differential.

In terms of production status, both are Active. The RX 7900 GRE launched on 2023-07-26 with a launch MSRP of 549 USD. The Intel part launches on 2026-04-15 with no MSRP recorded. The RX 7900 GRE has a successor in Navi IV, while the Intel part has no successor listed. The recorded data shows a clear hierarchy: the RX 7900 GRE is a high-throughput discrete card, and the Intel Arc Graphics 1 Xe Mobile is a low-power integrated unit. Every measured specification, from shading units to memory bandwidth to FP32 throughput, places the AMD card in a different performance class.
