Architecture Differences

The two GPUs differ fundamentally in design philosophy, process technology, and execution resources. The AMD Radeon RX 7900 GRE is built on TSMC's 5 nm process and packs 57,700 million transistors into a 529 mm² die, yielding a transistor density of 109.1M per mm². The Intel Arc Graphics 4 Xe Mobile is fabricated on Intel's 3 nm process, but the database records no transistor count, die size, or density figures for the chip.

The AMD part uses the RDNA 3.0 architecture with 5,120 shading units, 320 TMUs, 160 ROPs, and 80 ray tracing cores. The Intel part uses the Xe3-LPG architecture with 512 shading units, 32 TMUs, 16 ROPs, and 4 ray tracing cores. These execution resource counts differ by an order of magnitude, and the resulting compute rates reflect that gap. The AMD GPU delivers 45.98 TFLOPS of FP32 compute and 91.96 TFLOPS of FP16 compute (2:1 ratio). The Intel GPU delivers 2.355 TFLOPS of FP32 and 4.710 TFLOPS of FP16, again at a 2:1 ratio.

Memory architecture separates the two completely. The AMD Radeon RX 7900 GRE uses dedicated 16 GB GDDR6 memory on a 256-bit bus, with memory clocks at 2250 MHz and 18 Gbps effective, producing 576.0 GB/s of bandwidth. The Intel Arc Graphics 4 Xe Mobile integrates into the system with System Shared memory, System Shared type, System Shared bus width, and System Dependent bandwidth. The AMD card also shows a 1287 MHz base clock and 1880 MHz game clock, while the Intel part runs a 300 MHz base clock and a 2300 MHz boost clock.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Physical characteristics differ sharply: the AMD card is dual-slot with 2x 8-pin power connectors, a 600 W suggested PSU, PCIe 4.0 x16 interface, and dimensions of 276 mm length, 110 mm height, and 51 mm width. The Intel part is an IGP with no power connectors, no suggested PSU, and no recorded dimensions. The AMD GPU produces 359.2 GPixel/s pixel rate and 718.4 GTexel/s texture rate, while the Intel GPU produces 36.80 GPixel/s and 73.60 GTexel/s.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins in every scenario that demands dedicated graphics throughput. Its 16 GB GDDR6 frame buffer with 576.0 GB/s bandwidth supports high-resolution rendering and large texture sets. The 5,120 shading units and 80 ray tracing cores place it in a class for discrete desktop gaming and compute workloads. Its pixel rate of 359.2 GPixel/s and texture rate of 718.4 GTexel/s indicate the throughput needed for modern 3D applications.

The Intel Arc Graphics 4 Xe Mobile wins in scenarios constrained by power and physical footprint. At 25 W TDP with no power connectors and IGP implementation, it fits into portable devices where a 260 W dual-slot card cannot operate. The 2300 MHz boost clock shows that Intel's design compensates for its lower execution unit count with higher clock headroom. The System Shared memory model eliminates dedicated VRAM costs and allows the GPU to scale with system memory capacity.

The recorded benchmark data shows the AMD GPU has 10 individual benchmark scores, including 3DMark Steel Nomad DX12 at 4,814, Geekbench OpenCL at 175,758, Geekbench Vulkan at 99,850, and Passmark GPU Compute at 15,016. The Intel GPU has no recorded benchmark scores in the database, with an average benchmark score of 0 and a 50th percentile placement. The AMD GPU holds the 77th percentile among all GPUs.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the AMD Radeon RX 7900 GRE and Intel Arc Graphics 4 Xe Mobile. The head-to-head results list zero entries, and both win counters stand at zero. The Intel GPU has no individual benchmark scores of any kind.

The AMD Radeon RX 7900 GRE's standalone benchmark results provide the only measurable performance data. In 3DMark Steel Nomad DX12 it scores 4,814. In Geekbench OpenCL it scores 175,758 and in Geekbench Vulkan 99,850. Passmark results include DirectX 10 at 139, DirectX 11 at 300, DirectX 12 at 107, DirectX 9 at 310, G2D at 1,180, G3D at 27,089, and GPU Compute at 15,016. The average benchmark score across these tests is 32,456.

The nearest rivals for the AMD card show how its average score sits in context. The AMD FirePro S10000 averages 32,388 with a delta of 0.2%, meaning the RX 7900 GRE is effectively tied with it. The AMD FirePro S9300 X2 averages 32,540 with a delta of -0.3%, and the AMD Radeon RX 590 GME averages 32,601 with a delta of -0.4%. The AMD Radeon Pro 570X averages 32,176 with a delta of 0.9%. These deltas place the RX 7900 GRE within a narrow band of roughly 1% of its nearest rivals.

The Intel Arc Graphics 4 Xe Mobile has no rivals listed and no average score to compare. Its 50th percentile placement among all GPUs comes without supporting benchmark data, and its average benchmark score of 0 reflects the absence of recorded tests.

The Verdict

The data supports a clear split between these two products. The AMD Radeon RX 7900 GRE is a discrete, high-power desktop GPU with 5,120 shading units, 16 GB of dedicated GDDR6 memory, and 45.98 TFLOPS of FP32 compute. It holds the 77th percentile among all GPUs, has an average benchmark score of 32,456, and carries a launch MSRP of 549 USD. Its nearest rivals in the database all score within 0.9% of its average, confirming that the card sits in a competitive performance tier.

The Intel Arc Graphics 4 Xe Mobile is an integrated GPU for portable devices, built on a 3 nm process with a 25 W TDP and no power connectors. It has 512 shading units, 4 ray tracing cores, and a 2300 MHz boost clock, but it relies on System Shared memory with System Dependent bandwidth. The database contains no benchmark scores for this part, no average score, and no rival comparisons.

Users seeking a discrete GPU for demanding rendering tasks should select the AMD Radeon RX 7900 GRE based on its recorded performance data. Users constrained to integrated graphics in portable systems should consider the Intel Arc Graphics 4 Xe Mobile for its low power envelope and IGP form factor, but the absence of benchmark data means no quantitative performance assessment is possible from the database.
