AMD Radeon RX 7800M vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon RX 7800M and the Intel Arc G3. The head-to-head benchmark array is empty, and neither component records a win in a direct matchup. The AMD Radeon RX 7800M, however, has a substantial set of recorded benchmark scores, while the Intel Arc G3 has no recorded benchmark scores at all.

The AMD Radeon RX 7800M's average benchmark score across all recorded tests is 27,883. Its percentile ranking against all GPUs is 73, meaning it outperforms roughly three-quarters of the database's tracked graphics processors. Its nearest rivals in the database, based on average score, are the AMD Radeon Pro Vega 20 at 27,839 (a delta of 0.2%, meaning the RX 7800M is effectively tied), the AMD Radeon Pro W5500X at 27,973 (delta of -0.3%, effectively tied), the NVIDIA GeForce GTX 980 Ti at 28,020 (delta of -0.5%, effectively tied), and the AMD FirePro S7150 at 28,117 (delta of -0.8%, effectively tied). These deltas are all within a single percentage point, indicating that the RX 7800M sits in a performance cluster where small variations in test conditions can reorder results.

Looking at the RX 7800M's individual benchmark scores, the strongest showings come in compute-oriented workloads. The Geekbench Vulkan score is 126,668, and the Geekbench OpenCL score is 120,778. These two scores are close, suggesting the architecture delivers consistent compute performance across different API frontends. The 3DMark Steel Nomad DX12 score is 2,994, which is a lower number but represents a different, more graphics-intensive workload. In PassMark tests, the G3D score is 17,613, while the GPU compute score is 9,342. The DirectX 11 score is 176, DirectX 9 is 174, and DirectX 10 is 99, while DirectX 12 is 89. The G2D score is 892. The contrast between the high Vulkan and OpenCL scores and the lower DirectX scores indicates that the RX 7800M's compute throughput is strong, but its raw graphics pipeline performance in legacy DirectX tests is comparatively modest.

The Intel Arc G3, by contrast, has an empty benchmark array. It records an average benchmark score of 0 and a percentileVsAllGpus of 50, which is a default placeholder rather than a measured result. The database shows no nearest rivals for the Arc G3, which means there is no comparative data to establish its position. The absence of recorded scores for the Arc G3 prevents any quantitative head-to-head analysis between the two parts. All comparisons must therefore rely on architectural specifications and the RX 7800M's own benchmark results.

Architecture Differences

The AMD Radeon RX 7800M and Intel Arc G3 diverge fundamentally in their design philosophies. The RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, codenamed Wheat Nas, and belongs to the Navi Mobile (RX 7000M) generation. It is fabricated on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The Arc G3 uses the Panther Lake chip built on Xe3-LPG architecture, belongs to the Arc Graphics-M (Panther Lake) generation, and is fabricated on a 3 nm process at Intel. Its transistor count and die size are listed as unknown, with no density figure recorded.

The RX 7800M has 3,840 shading units, 240 texture mapping units, 96 raster output units, and 60 ray tracing cores. The Arc G3 has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. This is a 3x difference in shading units, a 6x difference in TMUs, and a 4.8x difference in ROPs. The RX 7800M's raw execution resources are substantially larger. The RX 7800M also has dedicated GDDR6 memory: 12 GB on a 192-bit bus with 432.0 GB/s bandwidth. The Arc G3 uses System Shared memory, with the bus width and type both listed as System Shared and the bandwidth as System Dependent. The RX 7800M's memory clock is 2250 MHz (18 Gbps effective), while the Arc G3's memory clock is listed as System Shared.

Clock speeds tell a different story. The RX 7800M has a base clock of 1295 MHz, a boost clock of 2335 MHz, and a game clock of 2145 MHz. The Arc G3 has a base clock of just 300 MHz and a boost clock of 2400 MHz. The Arc G3's boost clock is slightly higher than the RX 7800M's, but its base clock is much lower.

The Verdict

The data presents a clear performance hierarchy, but the comparison is incomplete. The AMD Radeon RX 7800M has extensive recorded benchmark scores, including a Geekbench Vulkan score of 126,668, a Geekbench OpenCL score of 120,778, and a PassMark G3D score of 17,613. Its percentile rank of 73 places it above the majority of tracked GPUs. The Intel Arc G3 has no recorded benchmarks, an average score of 0, and a default percentile of 50. Without measured scores, the Arc G3 cannot be positioned against the RX 7800M quantitatively.

The architectural specifications favor the RX 7800M in nearly every compute and graphics resource category. It has 3x the shading units, 6x the TMUs, 4.8x the ROPs, 6x the ray tracing cores, 5.8x the FP32 throughput, and 4.7x the pixel rate. Its dedicated 12 GB GDDR6 memory with 432.0 GB/s bandwidth provides predictable bandwidth, whereas the Arc G3's System Shared memory has System Dependent bandwidth. The RX 7800M's 346 mm² die with 28,100 million transistors on a 5 nm TSMC process is a large, high-power part at 180 W. The Arc G3's 3 nm Intel process at 25 W is a low-power integrated solution.

The release dates are separated by roughly 20 months, with the RX 7800M launching on 2024-09-10 and the Arc G3 dated 2026-05-31. The Arc G3 is a newer design on a smaller process node, but its resource counts and power envelope indicate a fundamentally different target. The RX 7800M is a discrete-class mobile GPU with high throughput and dedicated memory. The Arc G3 is an integrated GPU meant for low-power portable devices, sharing system memory.

The verdict from the recorded data is straightforward: the RX 7800M is the superior performer in absolute terms. Its benchmark scores, while not directly compared to the Arc G3, place it in the 73rd percentile of all GPUs, with nearest rivals clustered within 0.8% of its average score. The Arc G3's lack of recorded benchmarks means it has no demonstrated performance. The Arc G3's advantage lies in power efficiency and process technology, but the database provides no performance data to validate its capability.

Where Each One Wins

The AMD Radeon RX 7800M wins in every measurable performance category. Its benchmark scores demonstrate strength in compute workloads, with Geekbench Vulkan (126,668) and OpenCL (120,778) scores that show high throughput. The 3DMark Steel Nomad DX12 score of 2,994 indicates capable graphics rendering. The PassMark G3D score of 17,613 and GPU compute score of 9,342 confirm solid general-purpose and compute performance. Its nearest rivals are all within 0.8% of its average score, meaning it trades places with the AMD Radeon Pro Vega 20, AMD Radeon Pro W5500X, NVIDIA GeForce GTX 980 Ti, and AMD FirePro S7150. The RX 7800M's 12 GB GDDR6 memory with 432.0 GB/s bandwidth provides dedicated resources for texture-heavy and bandwidth-sensitive workloads.

The Intel Arc G3 wins in power efficiency and integration. Its 25 W TDP is 7.2x lower than the RX 7800M's 180 W. Its 3 nm Intel process node is more advanced than the 5 nm TSMC node used by the RX 7800M. Its boost clock of 2400 MHz is 65 MHz higher than the RX 7800M's 2335 MHz boost, suggesting it can reach high frequencies when needed despite the low base clock of 300 MHz. The System Shared memory architecture means it has no fixed memory allocation, which can be an advantage in systems where unified memory is preferred. The Arc G3's FP16 throughput of 12.29 TFLOPS (2:1) is half its FP32 rate, whereas the RX 7800M's FP16 is equal to its FP32, but the Arc G3's FP16 number is still substantial relative to its FP32.

The RX 7800M is the choice for workloads requiring high sustained throughput: large compute tasks, high-resolution texturing, and heavy ray tracing. The Arc G3 is the choice for ultra-low-power portable devices where 25 W is the ceiling and system shared memory is acceptable. The database shows no recorded benchmarks for the Arc G3, so its real-world performance remains unverified. The RX 7800M's recorded scores and 73rd percentile ranking give it a demonstrated performance profile, while the Arc G3's profile is entirely speculative. The data indicates that these are not competing products in the same segment; they serve different power and performance tiers.
