AMD Radeon Instinct MI60 vs AMD Radeon PRO W7600 Comparison

The data presents a fascinating generational clash between two very different AMD workstation philosophies. The AMD Radeon Instinct MI60, a 2018 data-center heavyweight, and the AMD Radeon PRO W7600, a 2023 workstation card, are separated by nearly five years of architecture evolution but land in the same performance percentile. The benchmark results show a split decision: the MI60 dominates in OpenCL compute, while the W7600 edges ahead in Vulkan, making the choice entirely dependent on the specific workload.

Head-to-Head Benchmarks

The most significant performance gap between these two cards appears in the Geekbench OpenCL test. The AMD Radeon Instinct MI60 scores 92,488 points, defeating the AMD Radeon PRO W7600's 81,528 points by a decisive 13.4%. This is a substantial margin that highlights the MI60's raw compute advantage in this specific API. The MI60's 14.75 TFLOPS of FP32 performance and 1.02 TB/s of memory bandwidth clearly translate into superior OpenCL throughput, making it the stronger choice for compute-heavy applications that rely on this framework.

However, the story flips in the Geekbench Vulkan test. Here, the AMD Radeon PRO W7600 scores 92,688 points, narrowly edging out the MI60's 92,444 points by a razor-thin 0.3% margin. While this delta is almost within the margin of error, it still represents a win for the newer architecture. The W7600's Vulkan 1.4 support and RDNA 3.0 design give it a slight edge in this more modern graphics API, suggesting better optimization for contemporary rendering workloads.

When placed in the broader context of their respective rival pools, the picture becomes clearer. The MI60's average benchmark score of 92,466 places it 0.9% ahead of the NVIDIA RTX A4500 (91,671) and 1.5% ahead of the RTX A4500 Mobile (91,134). However, it trails the AMD Radeon Pro VII (97,131) by 4.8% and the AMD Radeon RX 7900M (97,487) by 5.2%. This indicates that while the MI60 is competitive with professional NVIDIA offerings, it sits below the top tier of AMD's own lineup in raw average performance.

The W7600's average score of 87,108 tells a different story. It is essentially tied with the NVIDIA Quadro GP100 (87,445), trailing by just 0.4%. It beats the NVIDIA CMP 40HX (85,637) by 1.7%, but falls behind the RTX A4500 Mobile (91,134) by 4.4% and the RTX A4500 (91,671) by 5%. This positions the W7600 as a mid-tier performer, closer in raw benchmark terms to older NVIDIA flagship cards rather than the current professional lineup. Both cards achieve a 93rd percentile ranking among all GPUs, confirming they are both high-performance solutions, but their strengths are clearly compartmentalized.

The Verdict

The benchmark data delivers a clear verdict: the AMD Radeon Instinct MI60 is the superior choice for OpenCL-based compute workloads, while the AMD Radeon PRO W7600 is the better option for Vulkan-driven tasks and modern graphics pipelines. If your primary applications rely on OpenCL acceleration, the MI60's 13.4% lead in that specific benchmark is the decisive factor. Its 32 GB of HBM2 memory with 1.02 TB/s bandwidth provides a massive advantage for large datasets and memory-intensive compute, a feature set that the 8 GB GDDR6 configuration of the W7600 cannot match.

Conversely, if your workflow is centered on Vulkan rendering, the W7600's win, however marginal, signals better architectural compatibility. Its RDNA 3.0 architecture with 32 ray accelerators and support for DirectX 12 Ultimate makes it a more future-proof option for graphics-centric applications. The 0.3% lead in Vulkan, while small, is backed by the card's modern feature set, including DisplayPort 2.1 outputs and a significantly lower 130 W TDP. The data suggests that for a general-purpose workstation where power efficiency is a concern and Vulkan is the primary API, the W7600 is the pragmatic pick. For pure compute density and memory capacity, the MI60 remains the undisputed champion in this pairing.

Where Each One Wins

The AMD Radeon Instinct MI60 wins decisively in scenarios demanding maximum compute throughput on legacy or widely-deployed APIs. Its OpenCL score of 92,488 is the standout metric, making it the ideal candidate for scientific simulation, machine learning inference, or any workload that leverages OpenCL for general-purpose GPU computing. The 32 GB memory pool and 1.02 TB/s bandwidth are critical for handling data sets that exceed the capacity of smaller cards, and the 4096 shading units provide massive parallel processing capability. This is a card for large-scale compute, not for rendering a frame on a desktop.

The AMD Radeon PRO W7600 wins in modern graphics and efficiency-focused environments. Its Vulkan score of 92,688, while only slightly higher, demonstrates better optimization for the latest graphics API, which is increasingly used in professional DCC (digital content creation) tools and game engines. The inclusion of 32 ray accelerators and support for DirectX 12 Ultimate indicates readiness for ray-traced workflows. Furthermore, its 130 W TDP and single-slot design make it a far more manageable addition to a workstation, requiring only a 300 W power supply compared to the MI60's 700 W suggestion. The four DisplayPort 2.1 outputs also offer superior multi-monitor connectivity for professional visualization.

Architecture Differences

The two cards represent distinct architectural generations from AMD. The Radeon Instinct MI60 is built on the Vega 20 chip, utilizing the GCN 5.1 architecture. This is a mature design manufactured on a 7 nm process at TSMC, packing 13,230 million transistors onto a die size of 331 mm². The architecture is compute-oriented, with 4096 shading units and no dedicated ray tracing cores, reflecting its data-center origins. Its memory subsystem is a defining feature: 4096-bit HBM2 memory, which allows for the remarkable 1.02 TB/s bandwidth.

In contrast, the AMD Radeon PRO W7600 uses the Navi 33 chip, built on the newer RDNA 3.0 architecture. This "Hotpink Bonefish" codename design is manufactured on a more advanced 6 nm process, also by TSMC, and packs 13,300 million transistors into a smaller 204 mm² die. The RDNA 3.0 architecture is a significant departure, featuring a chiplet-inspired design philosophy and a focus on power efficiency. It includes 2048 shading units and 32 dedicated ray accelerators, which are absent on the MI60. The memory interface is narrower at 128-bit, using GDDR6 memory, which contributes to its lower power draw.

The architectural philosophies are clear: the MI60's GCN 5.1 is built for raw, sustained compute throughput with a massive memory pipeline, while the W7600's RDNA 3.0 is optimized for higher clock speeds, efficiency, and modern graphics features like ray tracing. The MI60's 7 nm node and 40.0M / mm² transistor density contrast with the W7600's 6 nm node and 65.2M / mm² density, demonstrating the leap in manufacturing efficiency between 2018 and 2023. The MI60 supports Vulkan 1.3, while the W7600 supports Vulkan 1.4, and the W7600 also supports DirectX 12 Ultimate (12_2) compared to the MI60's DirectX 12 (12_1).

Specification Differences

The specifications of these two cards diverge sharply across nearly every measurable category. The AMD Radeon Instinct MI60 has a base clock of 1200 MHz and a boost clock of 1800 MHz, while the AMD Radeon PRO W7600 runs significantly faster with a 1720 MHz base and a 2440 MHz boost. This clock speed advantage helps the W7600 achieve its higher FP32 performance of 19.99 TFLOPS, compared to the MI60's 14.75 TFLOPS. The FP16 performance follows the same pattern: the W7600 delivers 39.98 TFLOPS (2:1) versus the MI60's 29.49 TFLOPS (2:1).

The memory configuration is where the MI60 asserts its dominance. It features 32 GB of HBM2 memory on a 4096-bit bus, resulting in 1.02 TB/s of bandwidth. The W7600 has only 8 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth. The MI60's memory clock is 1000 MHz (2 Gbps effective), while the W7600's is 2250 MHz (18 Gbps effective). Despite the W7600's higher effective memory speed, the MI60's enormous bus width provides a 3.5x bandwidth advantage over the W7600.

The power and physical characteristics also differ drastically. The MI60 has a TDP of 300 W, requires a 700 W power supply, and uses 1x 6-pin + 1x 8-pin power connectors. It is a dual-slot card measuring 267 mm in length. The W7600 is far more efficient, with a 130 W TDP, a 300 W power supply recommendation, and a single 1x 6-pin connector. It is a single-slot card measuring 241 mm. The MI60 has a single mini-DisplayPort 1.4a output, whereas the W7600 offers four DisplayPort 2.1 outputs. The MI60 uses a PCIe 4.0 x16 interface, while the W7600 uses a PCIe 4.0 x8 interface. The MI60 was released on 2018-11-17 and is end-of-life, while the W7600 was released on 2023-08-02 and is active. The W7600 has a launch MSRP of 599 USD.
