AMD Radeon RX 7700 XT vs Intel Arc G3 Comparison

The Verdict

The AMD Radeon RX 7700 XT and Intel Arc G3 occupy entirely different segments of the graphics market. The RX 7700 XT is a discrete add-in board with a 245 W TDP, 12 GB of dedicated GDDR6 memory, and a full PCIe 4.0 x16 interface. The Arc G3 is an integrated graphics processor (IGP) built into Intel's Panther Lake mobile platform, with a 25 W TDP and system-shared memory. The recorded data shows the RX 7700 XT delivers an average benchmark score of 22549, placing it in the 67th percentile of all GPUs. The Arc G3 has no recorded benchmark scores in the database and sits at the 50th percentile, which reflects its status as an integrated solution rather than a performance comparison.

The RX 7700 XT is the only one of the two with measurable performance data. Its nearest rivals in the database are the NVIDIA GeForce RTX 5060 Mobile at 22435 (0.5% behind the AMD card), the NVIDIA GeForce RTX 4060 Mobile at 22729 (0.8% ahead), the NVIDIA GeForce RTX 2080 at 22895 (1.5% ahead), and the AMD Radeon RX 5700 at 22170 (1.7% behind). These deltas are all within roughly two percentage points, indicating the RX 7700 XT sits in a tightly contested performance band. For the Arc G3, the database contains no nearest rivals and no benchmark entries, so no direct comparative verdict can be made from measured data. The data indicates the RX 7700 XT is the choice for any workload requiring discrete GPU performance, while the Arc G3 serves as a low-power integrated option for portable systems where dedicated graphics are not present.

Architecture Differences

The RX 7700 XT uses the Navi 32 chip built on TSMC's 5 nm process, featuring RDNA 3.0 architecture under the "Wheat Nas" codename. It integrates 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The chip contains 3456 shading units, 216 texture mapping units, 96 raster operation pipelines, and 54 ray tracing cores. Its FP32 compute reaches 35.17 TFLOPS, with FP16 running at the same 35.17 TFLOPS in a 1:1 ratio.

The Arc G3 uses the Panther Lake chip built on Intel's 3 nm process, employing Xe3-LPG architecture from the Arc Graphics-M generation. The database lists its transistor count and die size as unknown. It has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. FP32 throughput is 6.144 TFLOPS, while FP16 reaches 12.29 TFLOPS in a 2:1 ratio. The shading unit count difference is substantial: the RX 7700 XT has 2.7 times more shaders, 5.4 times more TMUs, and 4.8 times more ROPs than the Arc G3.

Memory architecture separates the two decisively. The RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective). The Arc G3 uses system-shared memory, with bus width, type, and capacity all listed as system dependent. Its bandwidth is likewise system dependent. The RX 7700 XT achieves a pixel rate of 244.2 GPixel/s and a texture rate of 549.5 GTexel/s, while the Arc G3 manages 48.00 GPixel/s and 96.00 GTexel/s respectively.

Clock behavior also differs. The RX 7700 XT runs a 1435 MHz base clock, a 2171 MHz game clock, and a 2544 MHz boost clock. The Arc G3 has a 300 MHz base clock and a 2400 MHz boost clock, with no game clock listed. Power delivery reflects their roles: the RX 7700 XT draws 245 W with dual 8-pin connectors and a suggested 550 W PSU, while the Arc G3 draws 25 W, uses no power connectors, and has no suggested PSU. The RX 7700 XT is dual-slot with dimensions of 267 mm by 135 mm by 50 mm; the Arc G3 is an IGP with portable-device-dependent outputs and no listed dimensions.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the RX 7700 XT provides one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C, while the Arc G3's outputs are portable device dependent. The RX 7700 XT launched on 2023-09-05 and is active; the Arc G3 is scheduled for release on 2026-05-31 and is also listed as active. The RX 7700 XT has a launch MSRP of 449 USD. The Arc G3 has no launch MSRP recorded.

Where Each One Wins

The RX 7700 XT wins in every measured category because it is the only one with benchmark data. Its 3DMark Steel Nomad DX12 score is 3316. Geekbench OpenCL returns 138383, and Geekbench Vulkan returns 46443. Passmark results show 119 in DirectX 10, 232 in DirectX 11, 79 in DirectX 12, 294 in DirectX 9, 1161 in G2D, 22547 in G3D, and 12912 in GPU compute. The average benchmark score across all tests is 22549.

The Arc G3 has no recorded entries in any of these tests, so the database shows zero wins for it. The data cannot confirm any workload where the Arc G3 outperforms the RX 7700 XT. However, the Arc G3's specifications point to its intended role: a 25 W IGP with system-shared memory and no power connectors. It is designed for mobile platforms where the RX 7700 XT's 245 W draw, dual-slot footprint, and external power requirements are not viable. The RX 7700 XT, by contrast, is a desktop-oriented card with a 267 mm length and a 550 W suggested PSU.

The FP16 ratio also differs. The RX 7700 XT runs FP16 at a 1:1 ratio with FP32, both at 35.17 TFLOPS. The Arc G3 runs FP16 at a 2:1 ratio, delivering 12.29 TFLOPS versus 6.144 TFLOPS FP32. In compute workloads that can use FP16, the Arc G3's architecture provides double the throughput of its own FP32, but the absolute numbers remain far below the RX 7700 XT. The RX 7700 XT's 35.17 TFLOPS FP32 is 5.7 times the Arc G3's 6.144 TFLOPS.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RX 7700 XT and the Arc G3. The Arc G3 has an empty benchmark array, so all comparative analysis must rely on the RX 7700 XT's absolute scores and its nearest rivals.

The RX 7700 XT's 3DMark Steel Nomad DX12 score of 3316 represents its strongest single test in the DirectX 12 path. In Passmark's DirectX 11 test, it scores 232, which is nearly three times its DirectX 12 score of 79. The DirectX 9 result of 294 is the highest among the Passmark DirectX tests, followed by DirectX 10 at 119. Passmark G3D returns 22547, while G2D returns 1161. The GPU compute score of 12912 shows the card's throughput in non-graphics workloads.

Geekbench results show a large gap between OpenCL and Vulkan: 138383 in OpenCL versus 46443 in Vulkan. This means the OpenCL score is roughly three times the Vulkan score. The average benchmark score of 22549 sits close to the Passmark G3D result of 22547, indicating that the G3D test dominates the overall average.

Against its nearest rivals, the RX 7700 XT is 0.5% ahead of the NVIDIA GeForce RTX 5060 Mobile, whose average score is 22435. It trails the RTX 4060 Mobile by 0.8% (22729) and the RTX 2080 by 1.5% (22895). It leads the AMD Radeon RX 5700 by 1.7% (22170). These margins are narrow, and the data shows the RX 7700 XT performing within a two percent band of all four rivals. The RTX 2080 is the strongest competitor in the group, while the RX 5700 is the weakest.

The Arc G3's lack of benchmark data means no measured comparison can be made. Its 50th percentile ranking among all GPUs is based on no recorded scores, so it should not be interpreted as a performance level. The RX 7700 XT's 67th percentile, by contrast, is derived from its 22549 average across ten tests. The Arc G3's 6.144 TFLOPS FP32 and 48.00 GPixel/s pixel rate are the only quantitative performance indicators available, and both are far below the RX 7700 XT's 35.17 TFLOPS and 244.2 GPixel/s. The pixel rate difference is a factor of 5.1, and the FP32 difference is a factor of 5.7.

The RX 7700 XT also leads in texture rate: 549.5 GTexel/s versus 96.00 GTexel/s, a factor of 5.7. Its 54 ray tracing cores outnumber the Arc G3's 10 by a factor of 5.4. The RX 7700 XT's 28,100 million transistors on a 346 mm² die give it a density of 81.2 million per square millimeter; the Arc G3's transistor count is unknown. The RX 7700 XT's memory bandwidth of 432.0 GB/s is not comparable to the Arc G3's system-dependent figure. The RX 7700 XT uses a PCIe 4.0 x16 interface, while the Arc G3 is an IGP with no bus interface beyond the integrated path.
