AMD Radeon Pro W6600M vs AMD Radeon RX 9070 GRE Comparison

AMD Radeon Pro W6600M and AMD Radeon RX 9070 GRE occupy opposite ends of AMD’s GPU spectrum, with the former being an end-of-life mobile workstation part and the latter an active desktop gaming card. The data shows a clear separation in raw compute, memory capacity, and architectural maturity, but each card has a distinct purpose based on its benchmark profile and physical design. The Pro W6600M, built on RDNA 2.0, is a 90 W IGP solution with 8 GB of GDDR6, while the RX 9070 GRE, using RDNA 4.0, is a 220 W dual-slot card with 12 GB of GDDR6 and a PCIe 5.0 interface. Their head-to-head benchmark results, though limited, reveal a decisive winner in compute workloads, yet the W6600M’s integrated form factor and lower power envelope make it relevant for specific mobile applications.

Where Each One Wins

The AMD Radeon RX 9070 GRE is the clear victor in every measured benchmark category. In the only direct head-to-head test available—Geekbench OpenCL—the RX 9070 GRE scores 109,309, which is 48.6% higher than the Pro W6600M’s 56,140. This is a massive gap that reflects the newer architecture’s advantages: the RX 9070 GRE has 3,072 shading units versus 1,792 on the W6600M, 192 TMUs versus 112, 96 ROPs versus 64, and 48 RT cores versus 28. The FP32 compute throughput tells the same story: 34.28 TFLOPS for the RX 9070 GRE compared to 7.290 TFLOPS for the W6600M, a 4.7x difference. Memory bandwidth also heavily favors the RX 9070 GRE, with 432.0 GB/s against 224.0 GB/s, and its 12 GB frame buffer exceeds the W6600M’s 8 GB.

However, the Pro W6600M wins in the context of power efficiency and physical footprint. Its 90 W TDP is less than half of the RX 9070 GRE’s 220 W, and its IGP slot width means it requires no dedicated power connectors, whereas the RX 9070 GRE needs two 8-pin connectors and a 550 W suggested PSU. For mobile workstations where thermal headroom and battery life are critical, the W6600M’s lower power draw is a practical advantage, even if its performance is far lower. The W6600M also has a higher percentile rank among all GPUs (89th) compared to the RX 9070 GRE’s 87th, indicating that despite being older, the workstation card’s relative performance in its niche is slightly stronger than the gaming card’s in its own.

The RX 9070 GRE also wins on architectural features, supporting PCIe 5.0 x16 versus PCIe 4.0 x16 on the W6600M, and offering a game clock of 2220 MHz with a boost of 2790 MHz, compared to the W6600M’s base of 1224 MHz and boost of 2034 MHz. The newer card’s memory operates at 18 Gbps effective versus 14 Gbps, and its FP16 throughput is 34.28 TFLOPS (1:1), while the W6600M’s FP16 is 14.58 TFLOPS (2:1), meaning the RX 9070 GRE handles half-precision workloads without the rate penalty.

The Verdict

The data points to a simple conclusion: the AMD Radeon RX 9070 GRE is the superior GPU for almost any task that requires raw compute, memory bandwidth, or modern feature support. Its OpenCL score is 48.6% higher, its FP32 output is 4.7x greater, and its memory bandwidth is nearly double. For gaming, content creation, or general-purpose compute, the RX 9070 GRE is the definitive choice. Its 12 GB VRAM is 50% larger than the W6600M’s 8 GB, which matters for high-resolution textures or large datasets. The card’s active production status and 2025 release date also mean ongoing driver support and availability.

The Pro W6600M, by contrast, is only viable in scenarios where its IGP form factor and 90 W power draw are non-negotiable. It is designed for thin-and-light mobile workstations where a discrete card with external power connectors cannot fit. Its 89th percentile ranking suggests it performs well relative to all GPUs, but that ranking is diluted by the fact that it competes against integrated graphics and older mobile parts. In a direct performance comparison, the W6600M loses on every metric, and its end-of-life status means it should only be considered for legacy systems or specific OEM deployments.

For a builder or user choosing between these two, the decision is straightforward: pick the RX 9070 GRE unless the system physically cannot accommodate a dual-slot, 220 W card. The RX 9070 GRE’s launch MSRP is 549 USD, which positions it as a mid-range desktop option, while the W6600M has no MSRP listed, reflecting its OEM-only mobile focus. The Verdict is not close—the RX 9070 GRE wins on raw performance, memory, and future-proofing, while the W6600M retains value only as a low-power integrated solution for portable workstations where performance expectations are modest.

Head-to-Head Benchmarks

The single head-to-head benchmark available is Geekbench OpenCL, and it is a decisive win for the AMD Radeon RX 9070 GRE. The RX 9070 GRE scores 109,309, while the Pro W6600M scores 56,140, yielding a delta of -48.6% for the W6600M. This means the RX 9070 GRE is 94.7% faster in OpenCL compute, a near-doubling of performance. This result is consistent with the underlying specifications: the RX 9070 GRE has 1,280 more shading units, 80 more TMUs, 32 more ROPs, and 20 more RT cores than the W6600M. The clock speeds also favor the RX 9070 GRE, with a boost of 2790 MHz versus 2034 MHz, and its FP32 throughput of 34.28 TFLOPS dwarfs the W6600M’s 7.290 TFLOPS.

There is no Geekbench Vulkan score for the RX 9070 GRE, but the W6600M’s Vulkan score is 67,652, which is higher than its OpenCL score, suggesting the older card performs relatively better in Vulkan workloads. However, without a direct comparison, this cannot be verified. The RX 9070 GRE also has a 3DMark Steel Nomad DX12 score of 5,424, which is a modern gaming benchmark, while the W6600M has no such score, indicating it was not tested in that scenario. The average benchmark score across all tests reinforces the RX 9070 GRE’s edge: 57,367 for the RX 9070 GRE versus 61,896 for the W6600M, but note that the W6600M’s average is skewed by its inclusion of both OpenCL and Vulkan scores, while the RX 9070 GRE’s average includes the lower 3DMark score.

The deltaPct values in the nearestRivals data provide context. The W6600M’s closest rival is the AMD Radeon 8050S (avg score 62,108, delta -0.3%), meaning the W6600M is essentially tied with that card. The RX 9070 GRE’s closest rival is the Intel Arc A580 (avg score 57,756, delta -0.7%), showing it is also in a tight competitive band. Notably, the RX 9070 GRE’s nearest rivals include the AMD Radeon RX 6950 XT (avg score 58,392, delta -1.8%), which is a previous-generation high-end card, yet the RX 9070 GRE trails it by only 1.8% on average, despite being a newer and differently positioned product. This suggests the RX 9070 GRE’s performance is competitive with older flagship parts.

Architecture Differences

The two GPUs are built on entirely different architectures and process nodes. The Pro W6600M uses the Navi 23 chip with RDNA 2.0 architecture, fabricated on a 7 nm TSMC process, while the RX 9070 GRE uses the Navi 48 chip with RDNA 4.0, on a 4 nm TSMC process. The transistor counts reflect the generational leap: the W6600M has 11,060 million transistors on a 237 mm² die, giving a density of 46.7 million transistors per mm². In contrast, the RX 9070 GRE packs 53,900 million transistors onto a 357 mm² die, achieving a density of 151.0 million per mm²—more than triple the transistor density of the older chip. This explains the RX 9070 GRE’s massive compute advantage despite a die that is only 50% larger.

Memory architecture also differs significantly. The W6600M uses GDDR6 on a 128-bit bus with 8 GB capacity, while the RX 9070 GRE uses GDDR6 on a 192-bit bus with 12 GB, resulting in bandwidth of 224.0 GB/s and 432.0 GB/s, respectively. The RX 9070 GRE’s memory clock is 2250 MHz (18 Gbps effective), versus 1750 MHz (14 Gbps effective) on the W6600M. The newer card also supports PCIe 5.0 x16, doubling the interface bandwidth of the W6600M’s PCIe 4.0 x16.

Compute and feature-set differences are stark. The RX 9070 GRE has 3,072 shading units, 192 TMUs, 96 ROPs, and 48 RT cores, compared to 1,792, 112, 64, and 28 on the W6600M. The FP32 performance is 34.28 TFLOPS on the RX 9070 GRE versus 7.290 TFLOPS on the W6600M, and the FP16 throughput is 34.28 TFLOPS (1:1) versus 14.58 TFLOPS (2:1). Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but the RX 9070 GRE offers newer display outputs (1x HDMI 2.1b and 3x DisplayPort 2.1a) while the W6600M’s outputs are portable-device dependent. The RX 9070 GRE also has a game clock of 2220 MHz and a boost of 2790 MHz, while the W6600M’s base is 1224 MHz and boost is 2034 MHz. The W6600M’s predecessor is FirePro Mobile, while the RX 9070 GRE’s predecessor is Navi III, indicating a full generational shift in AMD’s product stack.
