AMD Radeon RX 7400 vs Intel Arc G3 Extreme Comparison

Where Each One Wins

The recorded data presents a stark contrast between these two graphics solutions. The AMD Radeon RX 7400 has a complete set of benchmark scores across eight tests, while the Intel Arc G3 Extreme has no recorded benchmark entries in the database. This means the AMD part wins every measurable comparison by default, not because of a narrow technical edge, but because the Intel part lacks any submitted performance data.

The AMD Radeon RX 7400 delivers its strongest showing in PassMark G3D with a score of 11,897, which is its highest raw performance figure. The PassMark G2D score of 1,209 indicates the 2D and desktop composition workload is handled comfortably. Compute performance is substantial as well, with a PassMark GPU Compute score of 5,152, showing the architecture can handle general purpose workloads beyond just graphics rendering.

The legacy DirectX tests reveal an interesting pattern. The PassMark DirectX 9 score of 176 is the highest among the DirectX API tests, while DirectX 10 drops to 59, DirectX 11 comes in at 97, and DirectX 12 falls to 44. This suggests the Radeon RX 7400 maintains strong compatibility with older API workloads, though the modern DirectX 12 result is comparatively lower. The 3DMark Steel Nomad DX12 score of 1,103 provides a modern gaming metric, and the average benchmark score across all tests sits at 2,467.

The Intel Arc G3 Extreme, by contrast, has a percentile rank of 50 against all GPUs, which is notably higher than the AMD part's 17th percentile. However, this percentile is derived from its hardware classification rather than measured performance, since the database contains zero benchmark entries for the Intel product. The average benchmark score for the Intel part is recorded as 0, confirming the absence of test data.

Architecture Differences

The fundamental architectural split between these two parts is substantial. The AMD Radeon RX 7400 uses the Navi 33 chip built on the RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III generation within the RX 7000 series. It is manufactured by TSMC on a 6 nm process node with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter.

The Intel Arc G3 Extreme uses the Panther Lake chip built on the Xe3-LPG architecture and belongs to the Arc Graphics-M generation for Panther Lake. It is manufactured by Intel on a 3 nm process node. The transistor count and die size are listed as unknown in the database, so no direct comparison of those physical characteristics is possible.

The compute resources differ significantly. The AMD part contains 1,792 shading units, 112 texture mapping units, and 64 raster operation units, along with 28 ray tracing cores. The Intel part has 1,536 shading units, 48 texture mapping units, and 24 raster operation units, with 12 ray tracing cores. This means the AMD chip has roughly 17% more shading units, but more than double the texture mapping units and significantly more raster operation units.

Clock behavior is another major differentiator. The AMD Radeon RX 7400 runs at a base clock of 1,452 MHz, a game clock of 2,200 MHz, and a boost clock of 2,300 MHz. The Intel Arc G3 Extreme has a much lower base clock of 300 MHz but a higher boost clock of 2,500 MHz. The wide gap between base and boost on the Intel part suggests a power management strategy that relies heavily on boost states, while the AMD part maintains a higher sustained clock floor.

The memory subsystems are entirely different in philosophy. The AMD Radeon RX 7400 has dedicated 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth at 2,250 MHz with 18 Gbps effective speed. The Intel Arc G3 Extreme uses system shared memory, with the memory type, bus width, and bandwidth all dependent on the host system. This is a fundamental design distinction: one is a discrete GPU with its own memory pool, the other is an integrated graphics processor that borrows from system memory.

Head-to-Head Benchmarks

The head-to-head benchmark data contains no entries, and the wins counter shows zero for both parts. This means the database has no direct comparative tests between the AMD Radeon RX 7400 and the Intel Arc G3 Extreme. The only performance data available is the AMD part's eight individual benchmark scores.

The AMD Radeon RX 7400's benchmark results show a clear performance hierarchy across different workloads. The PassMark G3D score of 11,897 is the dominant figure, indicating strong overall 3D rendering capability. The PassMark G2D score of 1,209 shows 2D acceleration is roughly one-tenth the performance of the 3D score, which is a typical ratio for discrete GPUs.

In the DirectX API tests, the scores vary substantially. The DirectX 9 score of 176 is nearly four times the DirectX 12 score of 44. The DirectX 11 score of 97 sits between the two, while the DirectX 10 score of 59 rounds out the legacy API results. This pattern suggests the architecture's efficiency degrades as the API abstraction layer becomes more complex, with modern DirectX 12 workloads proving the most demanding.

The 3DMark Steel Nomad DX12 score of 1,103 provides a standardized modern gaming metric. Combined with the PassMark GPU Compute score of 5,152, it indicates the card handles both gaming and compute workloads, though compute performance is substantially higher than the DirectX 12 gaming score would suggest.

The nearest rivals for the AMD Radeon RX 7400, based on average benchmark score, are the AMD Radeon 8040S at 2,440 with a 1.1% delta, the NVIDIA GeForce 710M at 2,433 with a 1.4% delta, the Intel HD Graphics 610 at 2,425 with a 1.8% delta, and the NVIDIA GeForce GT 710M at 2,422 with a 1.9% delta. The Radeon RX 7400's average score of 2,467 places it just ahead of all four rivals, but the margins are extremely tight, ranging from 1.1% to 1.9%. This indicates the Radeon RX 7400 sits in a performance tier where its closest competitors are all within a 2% band.

The Intel Arc G3 Extreme has no benchmark scores and no nearest rivals recorded. Its percentile rank of 50 against all GPUs is based on its hardware characteristics rather than measured performance. The absence of test data means no quantitative comparison can be made between the two parts beyond the specification differences already detailed.

The recorded data confirms that the AMD Radeon RX 7400 is a fully measured, shipping product with eight benchmark results, while the Intel Arc G3 Extreme is a hardware entry without performance validation. Any performance comparison between the two must therefore rely on the architectural specifications, where the AMD part shows advantages in shading units, texture mapping units, raster operation units, ray tracing cores, fill rates, and compute throughput, while the Intel part counters with a smaller process node, a higher boost clock, and a higher TDP envelope.
