AMD Instinct MI300 vs AMD Radeon PRO W7700 Comparison

AMD Instinct MI300 is a data center compute accelerator built on CDNA 3.0 architecture, while AMD Radeon PRO W7700 is a workstation graphics card built on RDNA 3.0 architecture. Both share a 5 nm TSMC manufacturing process, but they diverge sharply in purpose, memory design, and feature set. The database contains benchmark scores only for the Radeon PRO W7700, so direct measured comparisons are limited, but the specification records provide a clear picture of their respective roles.

Architecture Differences

The Instinct MI300 is built on CDNA 3.0, an architecture designed for dense compute and memory throughput. It uses 14080 shading units, 880 texture mapping units, and 0 ROPs, which indicates it is not intended for rasterization. Its pixel rate is recorded as 0 MPixel/s, confirming the absence of a traditional graphics output pipeline. The texture rate is 1,496.0 GTexel/s, a large figure driven by the high shading unit count.

The Radeon PRO W7700 uses RDNA 3.0, a graphics-first architecture. It has 3072 shading units, 192 TMUs, 96 ROPs, and 48 ray tracing cores. Its pixel rate is 249.6 GPixel/s and its texture rate is 499.2 GTexel/s. The presence of ROPs and ray tracing cores makes it a fully featured GPU for real-time rendering, while the Instinct MI300 lacks these units entirely.

Memory architecture separates the two products more than any other factor. The Instinct MI300 uses 128 GB of HBM3 with an 8192-bit bus, producing 5.32 TB/s of bandwidth. The Radeon PRO W7700 uses 16 GB of GDDR6 with a 256-bit bus, producing 576.0 GB/s. That is a 9.2x difference in memory capacity and a similar magnitude difference in bandwidth. For workloads that stream large datasets through the GPU, the MI300 holds a decisive structural advantage.

The MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz, with memory clocked at 1300 MHz (5.2 Gbps effective). The Radeon PRO W7700 runs a base clock of 1900 MHz and a boost clock of 2600 MHz, with memory at 2250 MHz (18 Gbps effective). The workstation card operates at dramatically higher frequencies, which suits latency-sensitive graphics tasks.

Compute throughput also differs in type. The Instinct MI300 achieves 47.87 TFLOPS FP32 and 47.87 TFLOPS FP16 (1:1 ratio). The Radeon PRO W7700 achieves 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1 ratio). The MI300 has more FP32 throughput, while the W7700 has more FP16 throughput due to its 2:1 rate. The 1:1 ratio on the MI300 suggests its FP16 path is not doubled relative to FP32, which is a common design for compute accelerators that prioritize consistent throughput.

The MI300 uses a PCIe 5.0 x16 interface, while the W7700 uses PCIe 4.0 x16. The newer bus standard on the MI300 provides higher transfer ceiling for host-to-device communication. The W7700 is a dual-slot card measuring 241 mm (9.5 inches) in length and 111 mm (4.4 inches) in height. The MI300 measures 267 mm (10.5 inches) in length and 111 mm (4.4 inches) in height. The MI300 is physically longer.

Power requirements are recorded differently. The MI300 has a TDP of 600 W, uses 2x 8-pin power connectors, and recommends a 1000 W power supply. The W7700 has a TDP of 190 W, uses a single 8-pin connector, and recommends a 450 W power supply. The MI300 demands more than three times the board power of the W7700.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark records between the Instinct MI300 and Radeon PRO W7700. The head-to-head section in the record is empty, and the wins counter shows 0 for both devices. Consequently, there are no measured performance deltas to report from direct comparisons.

The Radeon PRO W7700 does have standalone benchmark scores. Its Geekbench OpenCL score is 108,245, and its Geekbench Vulkan score is 129,706. The average of those two runs is 118,976. These numbers place the W7700 at the 95th percentile among all GPUs, which is a strong position in the database.

The nearest rivals for the W7700 provide context. The NVIDIA GB10 has an average score of 117,393, which is 1.3% lower than the W7700. The NVIDIA RTX 4000 SFF Ada Generation has an average score of 117,088, 1.6% lower. The NVIDIA Tesla V100 SXM2 16 GB scores 114,395, 4% lower. The NVIDIA RTX A5500 Mobile scores 113,944, 4.4% lower. The W7700 leads all four of these recorded rivals, with margins ranging from 1.3% to 4.4%.

Because the Instinct MI300 has no benchmark entries, its percentile is listed at 50, which reflects the absence of measured data rather than a performance estimate. The average benchmark score for the MI300 is recorded as 0, again indicating no measurements exist in this database. Any direct performance comparison between the two cards must rely on architectural specifications rather than measured results.

The FP32 throughput difference favors the MI300: 47.87 TFLOPS versus 31.95 TFLOPS, a 49.8% advantage. The FP16 throughput favors the W7700: 63.90 TFLOPS versus 47.87 TFLOPS, a 33.5% advantage. These are theoretical peak figures, not application benchmarks, but they indicate which device has more raw compute in each precision class.

Memory bandwidth is the largest head-to-head specification gap. The MI300 delivers 5.32 TB/s against the W7700's 576.0 GB/s, which is roughly 9.2x higher. For memory-bound workloads, that difference is more consequential than raw TFLOPS.

The Verdict

The data shows two devices engineered for different segments. The Instinct MI300 is a compute accelerator with no display outputs, no graphics API support, and an enormous HBM3 memory pool. The Radeon PRO W7700 is a workstation graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus four DisplayPort 2.1 outputs.

For compute workloads that fit within the MI300's design parameters, the specification record points strongly toward that card. It has 128 GB of HBM3, 5.32 TB/s bandwidth, 47.87 TFLOPS FP32, and a PCIe 5.0 x16 interface. The absence of graphics pipelines is not a flaw for such tasks; it is a sign of specialization.

For graphics workloads, the W7700 is the clear choice from the recorded data. It has 96 ROPs, 48 ray tracing cores, 249.6 GPixel/s pixel rate, and 63.90 TFLOPS FP16. It also has a 95th percentile ranking among all GPUs, with an average benchmark score of 118,976. The MI300 has no graphics benchmarks or outputs recorded.

The power requirements also separate the two. The MI300 needs 600 W and a 1000 W power supply recommendation. The W7700 needs 190 W and a 450 W recommendation. A system builder targeting a single-slot workstation with moderate power draw would find the W7700 more practical based on these figures.

The verdict is not about which card is faster in absolute terms, but which one serves a given task. The MI300 is built for memory-intensive compute acceleration. The W7700 is built for interactive graphics and rendering. The recorded data supports that distinction clearly.

Where Each One Wins

The Instinct MI300 wins in compute-heavy scenarios that depend on raw memory throughput and large working sets. Its 128 GB HBM3 pool and 5.32 TB/s bandwidth are unmatched in this comparison. The 47.87 TFLOPS FP32 figure also exceeds the W7700's 31.95 TFLOPS by 49.8%. The PCIe 5.0 x16 interface provides a faster host connection. The 153,000 million transistor count and 1017 mm² die size indicate a device built for maximum parallel compute density.

The Radeon PRO W7700 wins in graphics and rendering workloads. It has 96 ROPs, 48 ray tracing cores, and a 249.6 GPixel/s pixel rate, while the MI300 has 0 ROPs and 0 MPixel/s. The W7700 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it drives four DisplayPort 2.1 outputs. Its FP16 throughput of 63.90 TFLOPS is 33.5% higher than the MI300's 47.87 TFLOPS, which helps in workloads that use FP16 math. The 190 W TDP and 450 W PSU recommendation make it far easier to integrate into a workstation.

The W7700 also has measured benchmark data. It sits at the 95th percentile among all GPUs, with an average score of 118,976. It leads its nearest recorded rivals by margins of 1.3% to 4.4%. The MI300 has no recorded benchmarks, so its percentile of 50 is a placeholder for missing data, not a performance verdict.

For memory-bound compute, the MI300 is the logical pick based on specifications. For interactive graphics, ray tracing, and display output, the W7700 is the only viable option between the two. The data does not support using the MI300 for any task that requires a visible frame buffer, and it does not support using the W7700 for tasks that need hundreds of gigabytes of on-board memory. Each device wins in the domain it was designed to serve.
