AMD Radeon RX 6900 XT vs Intel Arc A730M Comparison

The AMD Radeon RX 6900 XT and Intel Arc A730M represent two very different approaches to graphics hardware, separated by market segment, physical design, and raw compute capability. The data shows a clear and consistent performance gap across every shared benchmark, with the desktop-focused AMD part dominating the mobile Intel part by margins that range from roughly 130% to 167%. The RX 6900 XT records 3 benchmark wins against 0 for the Arc A730M, establishing a definitive hierarchy in raw performance, though the architectural and specification differences explain why these two parts exist in entirely different product categories.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test is the most demanding shared workload, and it illustrates the performance chasm between the two GPUs. The AMD Radeon RX 6900 XT scores 4079 points, while the Intel Arc A730M manages only 1732 points. This translates to a 135.5% delta in favor of the AMD card, meaning the RX 6900 XT delivers more than double the performance in this modern DirectX 12 rasterization test. The margin is substantial enough that the Intel part appears to target a completely different performance tier, one more aligned with mid-range mobile gaming rather than enthusiast desktop rendering.

Compute workloads show an even wider gap. In Geekbench OpenCL, the RX 6900 XT scores 187673, which is 166.8% higher than the Arc A730M’s 70352. The 117,321-point absolute difference dwarfs the total score of the Intel GPU, indicating that the AMD architecture holds a massive advantage in general-purpose compute throughput. The Geekbench Vulkan result follows a similar pattern: the RX 6900 XT posts 148525 points versus 64693 for the Arc A730M, a 129.6% delta. While the Vulkan margin is the narrowest of the three tests, it still represents a performance ratio of roughly 2.3:1 in favor of AMD.

When placed in context with their respective peer groups, both GPUs sit at similar percentile rankings but with different absolute scores. The RX 6900 XT holds an 86th percentile ranking across all GPUs, with an average benchmark score of 50951. Its nearest rival is the NVIDIA CMP 50HX at 51790, which sits just 1.6% higher. The Arc A730M, meanwhile, holds an 84th percentile ranking with an average score of 45592, placing it 0.5% ahead of the AMD Radeon Pro 5500 XT and 1% behind the NVIDIA GeForce RTX 5090 Mobile. Despite the similar percentile placement, the 5359-point gap in average benchmark score between the two cards in question is significant, representing roughly a 12% difference in overall performance when averaged across all available tests.

Architecture Differences

The foundational architecture differs completely between these two parts. The RX 6900 XT uses AMD’s RDNA 2.0 architecture on the Navi 21 chip, part of the Navi II (RX 6000) generation. The Arc A730M uses Intel’s Xe-HPG architecture on the DG2-512 chip, belonging to the Alchemist (Arc 7 Mobile) generation. These are not just different implementations of similar ideas; they represent distinct design philosophies targeting different power envelopes and use cases.

Manufacturing processes also diverge. The AMD chip is built on a 7 nm process at TSMC, while the Intel chip uses a more advanced 6 nm process, also at TSMC. This process advantage helps Intel pack more transistors per square millimeter: the Arc A730M achieves a density of 53.4M transistors per mm², compared to 51.5M for the RX 6900 XT. However, the AMD chip is physically much larger, with a die size of 520 mm² versus 406 mm² for the Intel part. The total transistor count reflects this: the RX 6900 XT contains 26,800 million transistors, while the Arc A730M has 21,700 million, a difference of 5,100 million transistors in favor of AMD.

The memory subsystem also differs in capacity, type, and bandwidth. The RX 6900 XT features 16 GB of GDDR6 memory on a 256-bit bus, yielding a bandwidth of 512.0 GB/s. The Arc A730M has 12 GB of GDDR6 on a narrower 192-bit bus, resulting in 336.0 GB/s of bandwidth. The AMD card’s memory clock is 2000 MHz (16 Gbps effective), while the Intel card runs at 1750 MHz (14 Gbps effective). The 176 GB/s bandwidth advantage for the RX 6900 XT is substantial and directly impacts performance in memory-bound scenarios.

DirectX and Vulkan support are identical at the API level, with both GPUs supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software compatibility is not a differentiator; the performance gap comes from hardware execution resources rather than API feature support.

FAQ

A: The RX 6900 XT achieves a pixel rate of 288.0 GPixel/s and a texture rate of 720.0 GTexel/s. The Arc A730M achieves 196.8 GPixel/s and 393.6 GTexel/s, representing 46% lower pixel throughput and 83% lower texture throughput.

Specification Differences

The two GPUs differ across nearly every measurable specification. The RX 6900 XT uses a 7 nm process node, while the Arc A730M uses 6 nm. Transistor counts are 26,800 million versus 21,700 million, with die sizes of 520 mm² versus 406 mm². Transistor density is slightly higher on the Intel part at 53.4M per mm², compared to 51.5M per mm² for AMD.

Clock speeds show the AMD card running at 1825 MHz base and 2250 MHz boost, while the Intel card runs at 1100 MHz base and 2050 MHz boost. The RX 6900 XT also has a game clock of 2015 MHz, which the Arc A730M does not list. Memory clocks are 2000 MHz (16 Gbps effective) for AMD versus 1750 MHz (14 Gbps effective) for Intel.

Execution resources differ substantially. The RX 6900 XT has 5120 shading units, 320 TMUs, 128 ROPs, and 80 ray tracing cores. The Arc A730M has 3072 shading units, 192 TMUs, 96 ROPs, and 24 ray tracing cores. The AMD card holds a 67% advantage in shading units, a similar margin in TMUs, 33% more ROPs, and more than triple the ray tracing cores.

Memory configuration differs in size (16 GB versus 12 GB), bus width (256-bit versus 192-bit), and bandwidth (512.0 GB/s versus 336.0 GB/s). The power envelope is dramatically different: 300 W TDP with a triple-slot design and dual 8-pin power connectors for the RX 6900 XT, versus 80 W TDP with an IGP form factor and no power connectors for the Arc A730M. The AMD card requires a 700 W suggested PSU, while the Intel part lists no such requirement. Display outputs also differ: the RX 6900 XT offers 1x HDMI 2.1, 2x DisplayPort 1.4a, and 1x USB Type-C, while the Arc A730M lists "Portable Device Dependent" outputs.

Where Each One Wins

The AMD Radeon RX 6900 XT wins decisively in every performance category measured. It leads in 3DMark Steel Nomad DX12 by 135.5%, in Geekbench OpenCL by 166.8%, and in Geekbench Vulkan by 129.6%. It also holds advantages in FP32 compute (23.04 TFLOPS versus 12.60 TFLOPS), pixel rate (288.0 GPixel/s versus 196.8 GPixel/s), texture rate (720.0 GTexel/s versus 393.6 GTexel/s), and memory bandwidth (512.0 GB/s versus 336.0 GB/s). For desktop gaming, content creation, or any workload that demands maximum throughput, the RX 6900 XT is the clear choice.

The Intel Arc A730M wins in power efficiency and physical integration. Its 80 W TDP is 220 W lower than the RX 6900 XT’s 300 W, making it suitable for laptops and compact mobile systems where thermal and power constraints are critical. Its IGP form factor means it can be embedded directly into a motherboard without requiring expansion slots or external power connectors, which is impossible for the triple-slot RX 6900 XT. The Intel part also uses a more advanced 6 nm process, achieving higher transistor density per square millimeter, which is an engineering advantage even if it does not translate to higher performance in this comparison.

The Verdict

The benchmark data presents an unambiguous picture: the AMD Radeon RX 6900 XT outperforms the Intel Arc A730M by margins of 129.6% to 166.8% across all shared tests. The RX 6900 XT’s average benchmark score of 50951 sits 5359 points higher than the Arc A730M’s 45592, a 12% overall advantage. For users seeking maximum desktop performance, the RX 6900 XT is the only rational choice, provided the 300 W TDP and triple-slot form factor are acceptable.

The Arc A730M, however, is not without its merits. Its 80 W TDP and IGP design make it suitable for thin-and-light laptops where the RX 6900 XT cannot physically fit. The 6 nm process node and higher transistor density suggest Intel prioritized efficiency and integration over raw throughput. For mobile users who need a discrete-class GPU without the power requirements of a desktop card, the Arc A730M serves a purpose, but it cannot compete on absolute performance. The data shows that any workload that stresses the GPU will see a 2.3x to 2.7x advantage for the AMD part, making the choice between these two a matter of form factor and power budget rather than performance.
