AMD Radeon RX 6700S vs Intel Arc A750 Comparison

The AMD Radeon RX 6700S and Intel Arc A750 are two very different graphics cards that end up near each other in average benchmark scores, but they achieve that status through opposite strategies. The RX 6700S is a mobile-first, power-sipping part from the Radeon RX 6000 series, while the Arc A750 is a desktop-focused, power-hungry card from Intel’s Alchemist generation. The data shows the AMD card wins 6 of the 10 head-to-head benchmark comparisons, yet the Intel card takes the more demanding modern workloads. For a builder prioritizing a compact, low-power system with strong legacy API performance, the RX 6700S is the pick. For someone with a standard desktop PSU and a focus on DirectX 12 or compute-heavy tasks, the Arc A750 offers higher raw throughput.

The Verdict

The benchmark results indicate a split decision based on your system constraints and workload. The AMD Radeon RX 6700S is the better choice for portable or small-form-factor builds. Its 80 W TDP and IGP slot width mean it needs no power connectors and fits into the tightest chassis. It wins 6 out of 10 head-to-head tests, including a dominant 86.1% lead in Passmark DirectX 11 and a 20.2% lead in Passmark G3D. Its average benchmark score is 22154, which places it in the 67th percentile of all GPUs, slightly ahead of the Arc A750’s 20582 average and 66th percentile ranking.

The Intel Arc A750 is the better choice for a conventional desktop tower with a 550 W suggested PSU and a dual-slot slot width. It wins the most important future-facing test, 3DMark Steel Nomad DX12, by a massive 44.4% margin (2612 vs 1451). It also leads in Geekbench OpenCL by 28% and Vulkan by 11.1%. If your software leverages DirectX 12 or compute APIs, the Arc A750 is clearly the stronger performer, despite losing the overall head-to-head count. The RX 6700S is end-of-life, but the Arc A750 is also marked end-of-life, with a successor named Battlemage.

Where Each One Wins

The AMD Radeon RX 6700S dominates in legacy and 2D workloads. It wins Passmark DirectX 10 by 33.8%, DirectX 11 by 86.1%, DirectX 9 by 7.7%, and G2D by a narrow 1% (739 vs 732). Its Passmark G3D score of 15066 is 20.2% higher than the Arc A750’s 12534, suggesting better overall rasterization performance in older or less optimized game engines. It also wins Passmark GPU Compute by 11.6% (5990 vs 5368), which is surprising given the Intel card’s much higher theoretical FP32 output.

The Intel Arc A750 wins in modern, compute-oriented benchmarks. The 3DMark Steel Nomad DX12 result is its biggest victory, with a 44.4% higher score. It also takes Geekbench OpenCL with 98554 vs 70965, a 28% advantage, and Geekbench Vulkan with 85631 vs 76150, an 11.1% lead. The Passmark DirectX 12 test also goes to Intel, with a 17.1% margin (70 vs 58). This pattern shows Intel’s architecture is optimized for newer APIs and compute shaders, while AMD’s card excels in the older DirectX feature levels.

Architecture Differences

The two cards come from fundamentally different design philosophies. The AMD Radeon RX 6700S uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. It packs 11,060 million transistors into a 237 mm² die, giving a transistor density of 46.7 million per square millimeter. The Intel Arc A750 uses the DG2-512 chip with Xe-HPG architecture, made on a more advanced 6 nm TSMC process. It contains 21,700 million transistors on a much larger 406 mm² die, with a higher density of 53.4 million per square millimeter.

The compute resources are starkly different. The RX 6700S has 1792 shading units, 112 TMUs, and 64 ROPs, while the Arc A750 has exactly double the shading units at 3584, double the TMUs at 224, and double the ROPs at 112. Both have 28 ray tracing cores. The FP32 throughput reflects this: the Arc A750 delivers 17.20 TFLOPS versus 7.168 TFLOPS for the RX 6700S, and FP16 is 34.41 TFLOPS vs 14.34 TFLOPS. Memory configurations also differ: both have 8 GB of GDDR6, but the AMD card uses a 128-bit bus for 224.0 GB/s bandwidth, while the Intel card uses a 256-bit bus for 512.0 GB/s bandwidth. The Arc A750 also has a higher boost clock of 2400 MHz versus 2000 MHz, and a base clock of 2050 MHz versus 1700 MHz.

Power and interface requirements are the biggest practical difference. The RX 6700S is rated at 80 W TDP, requires no power connectors, and uses a PCIe 4.0 x8 interface. The Arc A750 is rated at 225 W TDP, needs a 1x 6-pin plus 1x 8-pin power connection, and uses a full PCIe 4.0 x16 slot. Display outputs also differ: the AMD card is “Portable Device Dependent,” while the Intel card offers 1x HDMI 2.1 and 3x DisplayPort 2.0.

Head-to-Head Benchmarks

The single biggest win for the Intel Arc A750 is in 3DMark Steel Nomad DX12. The Intel card scores 2612, which is 44.4% higher than the AMD card’s 1451. This is a decisive victory in a modern API test and suggests the Arc A750 has a significant architectural advantage in DirectX 12 workloads. The Geekbench OpenCL result follows a similar pattern, with Intel scoring 98554 versus AMD’s 70965, a 28% lead. Geekbench Vulkan is closer but still favors Intel, with 85631 vs 76150, an 11.1% margin. Passmark DirectX 12 also goes to Intel, with 70 vs 58, a 17.1% advantage.

The AMD Radeon RX 6700S has its largest win in Passmark DirectX 11, scoring 134 versus the Arc A750’s 72, a massive 86.1% difference. This is the most lopsided result in either direction. Passmark DirectX 10 also favors AMD, with 87 vs 65, a 33.8% win. Passmark G3D is another strong AMD result: 15066 vs 12534, a 20.2% margin. The AMD card also wins Passmark GPU Compute with 5990 vs 5368, an 11.6% lead, and Passmark DirectX 9 with 195 vs 181, a 7.7% edge. Passmark G2D is nearly tied, with AMD winning 739 vs 732, just a 1% difference.

Overall, the pattern is clear: Intel wins the modern, high-level API tests by large margins, while AMD wins the legacy DirectX 9/10/11 tests and the overall G3D score. The wins are split 6 for AMD and 4 for Intel, but the Intel wins are often larger in magnitude, particularly the 44.4% Steel Nomad and 28% OpenCL victories.

Specification Differences

The most obvious difference is in the process node and die size. The AMD Radeon RX 6700S uses a 7 nm process with an 11,060 million transistor count on a 237 mm² die. The Intel Arc A750 uses a 6 nm process with 21,700 million transistors on a 406 mm² die. The transistor density is 46.7 million per mm² for AMD and 53.4 million per mm² for Intel.

Clock speeds differ significantly. The RX 6700S has a base clock of 1700 MHz, a game clock of 1890 MHz, and a boost clock of 2000 MHz. The Arc A750 has a base clock of 2050 MHz and a boost clock of 2400 MHz, with no game clock listed. The memory clock is 1750 MHz (14 Gbps effective) for AMD and 2000 MHz (16 Gbps effective) for Intel.

Core counts are doubled on the Intel card: 3584 shading units vs 1792, 224 TMUs vs 112, and 112 ROPs vs 64. Both have 28 ray tracing cores. The pixel rate is 268.8 GPixel/s for Intel versus 128.0 GPixel/s for AMD, and the texture rate is 537.6 GTexel/s versus 224.0 GTexel/s. FP32 is 17.20 TFLOPS for Intel versus 7.168 TFLOPS for AMD, with FP16 at 34.41 TFLOPS vs 14.34 TFLOPS.

Power and physical specs are the biggest differentiators for real-world use. The RX 6700S has an 80 W TDP, an IGP slot width, and no power connectors. The Arc A750 has a 225 W TDP, a dual-slot width, and requires a 1x 6-pin + 1x 8-pin power connector, with a suggested PSU of 550 W. The bus interface is PCIe 4.0 x8 for AMD versus PCIe 4.0 x16 for Intel. Display outputs are portable-device-dependent for AMD, while Intel offers 1x HDMI 2.1 and 3x DisplayPort 2.0. The release dates are also different: January 2022 for the AMD card and October 2022 for the Intel card. The Intel Arc A750 has a launch MSRP of 289 USD, while the AMD card has no listed launch MSRP.
