AMD Radeon RX 7800 XT vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The AMD Radeon RX 7800 XT has an average benchmark score of 11,627 across the recorded database tests, placing it at the 51st percentile of all GPUs. The Intel Arc Graphics 2 Xe Mobile currently has no recorded benchmark scores in the database, so direct numerical comparisons are impossible. However, the available data for the RX 7800 XT shows a strong spread across individual tests. In 3DMark Steel Nomad DX12, it records 4,157 points. Geekbench OpenCL returns 18,290, while Geekbench Vulkan reaches 54,228. Passmark G3D shows 24,176, and Passmark GPU Compute delivers 13,473.

The RX 7800 XT's closest measured rival is the NVIDIA GeForce GTX 1660 with an average score of 11,680, a delta of -0.5 percent relative to the RX 7800 XT. That puts the two essentially at parity in aggregate terms. The AMD Radeon Pro 5500M trails by 0.9 percent with 11,528, the NVIDIA Tesla K20c trails by 1.3 percent with 11,479, and the AMD Radeon RX 6500 XT leads by 1.8 percent with 11,842. These four rivals all sit within roughly two percent of the RX 7800 XT, meaning the database places the card in a tightly packed performance cluster despite its modern architecture.

Because the Intel Arc Graphics 2 Xe Mobile has an empty benchmark array, the head-to-head section is one-sided. The data shows the RX 7800 XT as the only part with measurable performance, and the Intel part's percentile rating of 50 with an average score of 0 reflects no recorded results rather than a literal zero-performance outcome. The wins tally in the database is 0 for both parts, which is consistent with no overlapping test results.

Architecture Differences

The two GPUs come from different design philosophies. The AMD Radeon RX 7800 XT uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas, and belongs to the Navi III (RX 7000) generation. It is fabricated by TSMC on a 5 nm process with 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2 million per mm². The Intel Arc Graphics 2 Xe Mobile uses the Wildcat Lake chip on Xe3-LPG architecture, belongs to the Arc Graphics-M (Wildcat Lake) generation, and is fabricated by Intel on a 3 nm process. Its transistor count, die size, and density are recorded as unknown in the database.

Shading resources differ massively. The RX 7800 XT carries 3,840 shading units, 240 texture mapping units, 96 ROPs, and 60 ray tracing cores. The Intel part has 256 shading units, 16 TMUs, 8 ROPs, and 2 RT cores. Neither part lists tensor cores in the database. The RX 7800 XT reaches 37.32 TFLOPS FP32 and 37.32 TFLOPS FP16 at a 1:1 ratio. The Intel part delivers 1,280.0 GFLOPS FP32 and 2.560 TFLOPS FP16 at a 2:1 ratio. Pixel rate for the RX 7800 XT is 233.3 GPixel/s with a texture rate of 583.2 GTexel/s; the Intel part produces 20.00 GPixel/s and 40.00 GTexel/s.

Memory architecture is completely different. The RX 7800 XT uses 16 GB of GDDR6 on a 256 bit bus with 624.1 GB/s bandwidth and a memory clock of 2438 MHz, described as 19.5 Gbps effective. The Intel part uses system shared memory with system dependent bandwidth, no dedicated bus width, and no dedicated memory clock. Clock behavior also diverges: the RX 7800 XT has a 1295 MHz base, 2430 MHz boost, and 2124 MHz game clock; the Intel part has a 300 MHz base and 2500 MHz boost with no game clock recorded.

Power and physical design are opposites. The RX 7800 XT has a 263 W TDP, uses a dual-slot cooler, requires two 8-pin power connectors, and suggests a 600 W power supply. It measures 267 mm in length, 111 mm in height, and 50 mm in width. The Intel part has a 25 W TDP, is an integrated graphics processor with no slot width, no power connectors, no suggested PSU, and no recorded dimensions. The RX 7800 XT connects via PCIe 4.0 x16; the Intel part uses an IGP bus interface. Display outputs on the RX 7800 XT are one HDMI 2.1a and three DisplayPort 2.1; the Intel part lists portable device dependent outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The database shows two parts with almost no common ground. The AMD Radeon RX 7800 XT is a fully measured discrete GPU with an average score of 11,627 and a 51st percentile ranking. The Intel Arc Graphics 2 Xe Mobile is an integrated part with no recorded benchmarks, a 50th percentile placeholder, and system shared memory. Any user requiring recorded performance data should look to the RX 7800 XT, since the Intel part has zero measured results in the database. The RX 7800 XT also holds massive resource advantages: 3,840 shading units versus 256, 60 RT cores versus 2, and 16 GB of dedicated GDDR6 versus shared system memory.

The Intel part is the only one of the two that fits an integrated form factor with a 25 W TDP, no power connectors, and no dimensions. That makes it suitable for portable devices where the RX 7800 XT's 263 W TDP, dual-slot cooler, two 8-pin connectors, and 267 mm length would be physically impossible. The RX 7800 XT is the only part with a launch MSRP, listed at 499 USD. The Intel part has no launch MSRP recorded.

Where Each One Wins

The AMD Radeon RX 7800 XT wins on every measurable performance category in the database. It has the only recorded benchmark scores, the only dedicated memory subsystem, the higher compute throughput, the higher pixel and texture rates, and the larger shading and RT core counts. Its 37.32 TFLOPS FP32 output and 624.1 GB/s bandwidth place it clearly ahead of the Intel part's 1,280.0 GFLOPS FP32 and system dependent bandwidth. It also wins on expansion flexibility with PCIe 4.0 x16 and fixed display outputs of one HDMI 2.1a and three DisplayPort 2.1.

The Intel Arc Graphics 2 Xe Mobile wins on integration efficiency. Its 25 W TDP with no power connectors suits systems without discrete power delivery. Its IGP bus interface and system shared memory eliminate the need for separate VRAM. The 3 nm Intel process node gives it the smaller manufacturing geometry. Its boost clock of 2500 MHz is the higher of the two parts, though its base clock of 300 MHz is far lower. The Intel part also has a later release date of 2026-04-15 versus the RX 7800 XT's 2023-09-05. For a portable device where power draw and physical footprint matter more than raw throughput, the Intel part is the only viable option in this comparison. For any workload that requires measured GPU performance, the RX 7800 XT is the only part with data to support a choice.
