AMD Radeon Pro 455 vs AMD Radeon RX 7600 Comparison

Head-to-Head Benchmarks

The benchmark database records two direct comparisons between the AMD Radeon RX 7600 and the AMD Radeon Pro 455. The results are decisively one-sided. In Geekbench OpenCL, the RX 7600 scores 88,051 against the Pro 455's 10,336. That is a delta of 751.9% in favor of the RX 7600, a margin that reflects not merely a generational step but a fundamental difference in compute capability. The RX 7600 delivers nearly nine times the OpenCL throughput of the older Pro card.

The second recorded test, Geekbench Vulkan, shows a smaller but still commanding gap. The RX 7600 posts 34,401, while the Pro 455 manages 12,240. The resulting delta is 181.1%. Vulkan is a lower-level API that can expose raw hardware efficiency, and even there the RX 7600 more than doubles the Pro 455's score. Across the two shared benchmarks, the RX 7600 wins both, giving it a clean 2-0 record in the head-to-head data.

Looking at the broader database averages, the RX 7600 holds an average benchmark score of 15,171 across all recorded tests, while the Pro 455 averages 12,831. That is a difference of roughly 18% in aggregate performance. The RX 7600 also sits at the 57th percentile among all GPUs, versus the Pro 455's 52nd percentile. These percentile figures place both cards in the mid-range of the database, but the RX 7600's raw scores are consistently higher, especially in compute-heavy workloads where the architectural gap becomes most apparent.

Architecture Differences

The two cards come from entirely different design eras. The RX 7600 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. It is fabricated on a 6 nm process at TSMC with 13,300 million transistors spread across a 204 mm² die. That yields a transistor density of 65.2 million per square millimeter. The Pro 455, by contrast, uses the Baffin chip on GCN 4.0 architecture, part of the Radeon Pro Mac (400 Series) generation. It is built on a 14 nm process at GlobalFoundries with 3,000 million transistors on a 123 mm² die, giving a density of 24.4 million per square millimeter. The process node difference alone explains a large part of the performance gap: the RX 7600 packs more than four times the transistors into less than twice the die area.

The compute resources reinforce this divide. The RX 7600 has 2,048 shading units, 128 texture mapping units, and 64 render output units. The Pro 455 has 768 shading units, 48 TMUs, and only 16 ROPs. The RX 7600 also includes 32 ray tracing cores, a feature entirely absent from the Pro 455. This is not a minor addition; ray tracing support changes the types of workloads each card can handle, particularly in modern DirectX 12 Ultimate titles. The RX 7600 supports DirectX 12 Ultimate (12_2), while the Pro 455 is limited to DirectX 12 (12_0). Vulkan support also differs: the RX 7600 lists Vulkan 1.4, the Pro 455 lists Vulkan 1.3. OpenGL support is identical at 4.6.

Memory architecture is another clear separator. The RX 7600 comes with 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Pro 455 has 2 GB of GDDR5 memory on the same 128-bit bus, but only 81.28 GB/s of bandwidth. The RX 7600's memory clock is recorded at 2250 MHz (18 Gbps effective), while the Pro 455's memory runs at 1270 MHz (5.1 Gbps effective). The bandwidth difference is roughly 3.5 to 1, which directly impacts texture-heavy scenes and high-resolution framebuffers.

The RX 7600's pixel rate is 169.9 GPixel/s and its texture rate is 339.8 GTexel/s. The Pro 455 manages only 13.68 GPixel/s and 41.04 GTexel/s. FP32 compute is listed at 21.75 TFLOPS for the RX 7600 versus 1,313.3 GFLOPS for the Pro 455. Both cards list FP16 at the same ratio as FP32 (1:1), but the absolute numbers are vastly different. The RX 7600 is a modern discrete GPU designed for gaming and general compute; the Pro 455 is a low-power mobile workstation part from 2016, now marked end-of-life in the database.

The Verdict

The data points to an unambiguous conclusion: the AMD Radeon RX 7600 outperforms the AMD Radeon Pro 455 in every recorded benchmark. The OpenCL delta of 751.9% and the Vulkan delta of 181.1% are not close calls. The RX 7600 also has a higher average benchmark score (15,171 vs 12,831) and a higher percentile rank (57th vs 52nd). For any workload that relies on compute shaders, rendering, or modern graphics APIs, the RX 7600 is the superior choice.

The Pro 455, however, is not without its own niche. It is a 35 W MXM module with no power connectors, making it suitable for compact or portable systems where the RX 7600's 165 W TDP and dual-slot footprint would be impractical. The Pro 455's end-of-life status and 2 GB memory limit cap its usefulness in current software, but for legacy applications or low-power embedded uses, it may still function. The RX 7600, by contrast, is an active product with a 204 mm length, 115 mm height, and a single 8-pin power connector. It requires a 450 W suggested PSU. The choice is clear for performance: the RX 7600. The choice is clear for low-power integration: the Pro 455.

Where Each One Wins

The AMD Radeon RX 7600 wins in every measured performance category. It dominates compute workloads, as shown by the 751.9% OpenCL lead, and it is far ahead in graphics API performance, as shown by the 181.1% Vulkan lead. It also offers modern features like ray tracing, DirectX 12 Ultimate support, and a higher Vulkan version. For gaming, rendering, machine learning inference, or any GPU-accelerated task, the RX 7600 is the clear pick. Its 8 GB memory buffer and 288.0 GB/s bandwidth also make it viable for current titles and moderate-resolution textures.

The AMD Radeon Pro 455 wins only in low-power and form-factor constrained scenarios. Its 35 W TDP and MXM module design allow integration into systems where the RX 7600's 165 W dual-slot card would not fit or would exceed thermal budgets. The Pro 455's lack of power connectors simplifies installation in proprietary or compact chassis. However, its 2 GB GDDR5 memory and 81.28 GB/s bandwidth limit it to older or lighter workloads. The database shows no benchmark where the Pro 455 beats the RX 7600; its advantage is purely physical and thermal, not computational. For users who need maximum performance, the RX 7600 is the only choice. For users who need a low-profile, low-power GPU for legacy applications, the Pro 455 remains functional but obsolete.
