AMD Instinct MI455X vs AMD Radeon PRO V710 Comparison

The Verdict

The database comparison between the AMD Instinct MI455X and the AMD Radeon PRO V710 presents two radically different products with almost no overlap in intended use. The MI455X is a compute-oriented accelerator built on the CDNA 5.0 architecture, designed for massive parallel workloads that can use its 32768 shading units and 432 GB of HBM4 memory. The Radeon PRO V710 is a workstation card built on RDNA 3.0, optimized for professional graphics tasks with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support.

The recorded data shows the MI455X has no benchmark scores, no nearest rivals, and a 50th percentile ranking among all GPUs. The V710 has two recorded benchmark scores, an 88th percentile ranking, and four nearest rivals. Anyone choosing between these two cards should base the decision on whether the workload is compute-oriented or graphics-oriented. The MI455X targets environments where raw FP32 throughput, memory capacity, and bandwidth dominate. The V710 targets environments where API compatibility, established benchmark performance, and practical power delivery matter.

Architecture Differences

The MI455X uses the CDNA 5.0 architecture, a compute-focused design with a 2 nm process node from TSMC. It packs 320,000 million transistors on a 2990 mm² die, giving a transistor density of 107.0M per mm². This is a massive chip built for scale. The V710 uses the RDNA 3.0 architecture with the Navi 32 chip, built on a 5 nm process node from TSMC. It has 28,100 million transistors on a 346 mm² die, with a transistor density of 81.2M per mm².

The MI455X includes 32768 shading units, 1024 texture mapping units, and no ROPs. Its pixel rate is listed as 0 MPixel/s, which means it has no traditional rasterization output pipeline. The V710 has 3456 shading units, 216 TMUs, 96 ROPs, and 54 ray tracing cores. Its pixel rate is 192.0 GPixel/s, confirming it has a full graphics pipeline.

The MI455X supports no graphics APIs: DirectX, OpenGL, and Vulkan are all listed as N/A. The V710 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This difference is central to understanding the two products. The MI455X is not a graphics card in the traditional sense. The V710 is a fully featured workstation GPU with modern API support.

Memory architecture also differs sharply. The MI455X uses 432 GB of HBM4 on a 24576-bit bus, with 23.3 TB/s of bandwidth. The V710 uses 28 GB of GDDR6 on a 224-bit bus, with 504.0 GB/s of bandwidth. The MI455X has roughly 15.4 times the memory capacity and roughly 46.2 times the memory bandwidth, based on the recorded figures.

The MI455X has no display outputs. The V710 also has no display outputs. Both cards are designed for non-display workloads, but the V710 retains graphics API support for compute-in-graphics contexts.

Clock behavior differs substantially. The MI455X has a 1000 MHz base clock and a 2400 MHz boost clock. The V710 has a 1900 MHz base clock and a 2000 MHz boost clock. The V710 has a higher base clock by 900 MHz, but the MI455X has a higher boost clock by 400 MHz. Memory clocks are listed as 1900 MHz (7.6 Gbps effective) for the MI455X and 2250 MHz (18 Gbps effective) for the V710.

Power requirements diverge completely. The MI455X is rated at 2300 W TDP with a suggested PSU of 2700 W. It uses an EAM Module slot width and has no power connectors listed, meaning it draws power through its mounting interface. The V710 is rated at 158 W TDP with a suggested PSU of 450 W. It uses a single-slot design and a single 8-pin power connector.

Head-to-Head Benchmarks

The database has no direct head-to-head benchmark entries for these two cards. The MI455X has no benchmarks at all, so no score comparisons can be made between the two. However, the V710 has its own recorded measurements that provide context for its performance tier.

The V710 scores 853 in 3DMark Steel Nomad DX12. This is a modern DirectX 12 workload that stresses the full graphics pipeline. The V710's 96 ROPs, 54 ray tracing cores, and 192.0 GPixel/s pixel rate contribute to this result. The MI455X has no graphics pipeline, so it cannot run this test.

The V710 scores 116460 in Geekbench OpenCL. This measures general compute performance using the OpenCL API. The V710's FP32 throughput of 27.65 TFLOPS and FP16 throughput of 27.65 TFLOPS (1:1) inform this score. The MI455X lists no OpenCL support and no benchmark results.

The MI455X's FP32 figure of 157.3 TFLOPS is 5.7 times the V710's 27.65 TFLOPS, based on the recorded numbers. Its texture rate of 2,457.6 GTexel/s is 5.7 times the V710's 432.0 GTexel/s. These are theoretical peak figures, not measured scores. The database does not contain measured results for the MI455X.

The V710's average benchmark score of 58657 places it in the 88th percentile of all GPUs. Its nearest rival, the NVIDIA P102-100, scores 58528, a delta of 0.2%. The AMD Radeon RX 6950 XT scores 58392, a delta of 0.5%. The Intel Arc A570M scores 58239, a delta of 0.7%. The AMD Radeon RX 5600 OEM scores 58085, a delta of 1%. All four rivals are within one percent of the V710, indicating a tightly clustered performance band.

The MI455X sits at the 50th percentile with an average benchmark score of 0. This reflects the absence of recorded benchmarks, not a measured performance level.

Where Each One Wins

The MI455X wins decisively on raw compute specifications. Its FP32 throughput of 157.3 TFLOPS exceeds the V710's 27.65 TFLOPS by a factor of 5.7. Its memory bandwidth of 23.3 TB/s versus 504.0 GB/s gives it a 46.2 times advantage. Its 432 GB of HBM4 memory versus 28 GB of GDDR6 provides 15.4 times the capacity. For workloads that can use massive memory pools and extreme bandwidth, such as large-scale AI training, scientific simulation, or data center compute, the MI455X is the clear choice based on the recorded specifications.

The MI455X also wins on transistor scale. Its 320,000 million transistors on a 2990 mm² die are orders of magnitude beyond the V710's 28,100 million on 346 mm². The 2 nm process node with 107.0M transistors per mm² density indicates a more advanced manufacturing approach than the V710's 5 nm node with 81.2M per mm².

The V710 wins on practical deployability and measured performance. Its 158 W TDP and 450 W suggested PSU make it compatible with standard workstation power supplies. The MI455X requires a 2300 W TDP and a 2700 W suggested PSU, which demands specialized infrastructure. The V710 uses a single-slot form factor and one 8-pin connector. The MI455X uses an EAM Module slot width with no power connectors, indicating a proprietary mounting system.

The V710 wins on graphics feature support. It has 96 ROPs, 54 ray tracing cores, and a 192.0 GPixel/s pixel rate. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI455X has no ROPs, no ray tracing cores, and no graphics API support. Any workload that requires rasterization, ray tracing, or graphics API compatibility must use the V710.

The V710 wins on measured benchmark presence. Its 88th percentile ranking and average score of 58657 come from real test results. The MI455X has zero recorded benchmarks and sits at the 50th percentile by default. The V710's nearest rival comparisons show it performing within one percent of the NVIDIA P102-100, AMD Radeon RX 6950 XT, Intel Arc A570M, and AMD Radeon RX 5600 OEM.

The V710 wins on interface compatibility. It uses PCIe 4.0 x16, which is widely supported in existing systems. The MI455X uses PCIe 6.0 x16, a newer standard with limited deployment. The V710 also has a higher base clock of 1900 MHz versus 1000 MHz, which helps in latency-sensitive workloads.

The release dates differ by roughly two years, with the V710 releasing on 2024-10-02 and the MI455X on 2026-07-22. The V710 has an established track record. The MI455X is a newer product targeting a different segment. The predecessor names reflect this: the V710 follows the Radeon Pro Vega line, while the MI455X follows the Radeon Instinct line.

In summary, the MI455X is for compute environments that need maximum FP32 throughput, enormous memory capacity, and extreme bandwidth, accepting the infrastructure cost of a 2300 W device. The V710 is for professional graphics and compute workloads that require API support, ray tracing, practical power delivery, and verified benchmark performance. The data does not support using either card for the other's intended role.
