AMD Steam Deck OLED GPU vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark results between the AMD Steam Deck OLED GPU and the NVIDIA RTX PRO 4500 Blackwell Workstation. Both entries list zero benchmark scores, zero wins for either side, and no nearest rival comparisons. The average benchmark score for each is zero, and both sit at the 50th percentile against all GPUs in the database.

What the database does provide is a full specification profile for each part, which allows for a direct architectural comparison. The NVIDIA RTX PRO 4500 delivers 50.53 TFLOPS of FP32 compute, while the AMD Steam Deck OLED GPU delivers 1.638 TFLOPS. That places the workstation card at roughly 31 times the raw shader throughput, a gap driven by its 10,496 shading units versus 512, and its 2,407 MHz boost clock versus 1,600 MHz.

Memory bandwidth tells a similar story. The RTX PRO 4500 offers 896.0 GB/s over a 256-bit bus with GDDR7, while the Steam Deck GPU offers 176.0 GB/s over a 128-bit bus with LPDDR5. The workstation part also has 32 GB of memory versus 16 GB, and its pixel rate of 269.6 GPixel/s dwarfs the 25.60 GPixel/s of the Steam Deck GPU. Texture rate is 789.5 GTexel/s versus 51.20 GTexel/s.

The RTX PRO 4500 also carries 82 ray tracing cores and 328 tensor cores, whereas the Steam Deck GPU has 8 ray tracing cores and no tensor core entry in the data. In shading, texturing, rasterization, ray tracing, and memory throughput, the NVIDIA part leads in every measurable category. The AMD part has no recorded category in which it exceeds the workstation card.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Workstation wins on every metric where both parts have a recorded value. Its FP32 throughput of 50.53 TFLOPS is the defining advantage for compute-heavy workloads. The 328 tensor cores provide dedicated hardware for AI inference and training tasks, with FP16 performance matching FP32 at 50.53 TFLOPS (1:1). The 32 GB GDDR7 memory with 896.0 GB/s bandwidth supports large datasets and high-resolution rendering.

The AMD Steam Deck OLED GPU wins in power efficiency territory, though the data does not include a direct performance-per-watt calculation. Its TDP is 15 W versus 200 W for the RTX PRO 4500, a 13x difference in power draw. The Steam Deck GPU also uses a smaller die at 131 mm² versus 378 mm², and it pairs with 16 GB of LPDDR5 memory. For a low-power, integrated-class solution, the AMD part delivers 1.638 TFLOPS and 25.60 GPixel/s within a 15 W envelope.

The RTX PRO 4500 is a dual-slot card requiring a 550 W suggested power supply and a 16-pin power connector, while the Steam Deck GPU uses a single USB Type-C display output and has no separate power connector listed. The workstation card offers 4x DisplayPort 2.1b outputs, making it suited for multi-display professional setups. The Steam Deck GPU offers one USB Type-C output, matching a portable or embedded form factor.

Both parts support DirectX 12 Ultimate (12_2) and OpenGL 4.6. Vulkan support differs: the Steam Deck GPU supports Vulkan 1.3, while the RTX PRO 4500 supports Vulkan 1.4. The RTX PRO 4500 uses PCIe 5.0 x16, while the Steam Deck GPU has no bus interface listed.

The Verdict

The data points to a clear split in intended use. The NVIDIA RTX PRO 4500 Blackwell Workstation is the choice for any workload that demands maximum compute, memory capacity, or bandwidth. Its 50.53 TFLOPS FP32, 896.0 GB/s memory bandwidth, and 328 tensor cores place it in a different performance class entirely from the Steam Deck GPU. The 32 GB frame buffer and 269.6 GPixel/s pixel rate suit professional rendering, AI development, and large-scale data processing.

The AMD Steam Deck OLED GPU is the choice for a low-power, compact solution. Its 15 W TDP, 131 mm² die, and 16 GB LPDDR5 memory fit a handheld or embedded context. The 1.638 TFLOPS and 25.60 GPixel/s are modest but consistent with a console-class GPU. The lack of tensor cores and the 128-bit memory bus limit its reach, but the power budget is unmatched by the RTX PRO 4500.

Neither part has benchmark scores in the database, so a direct performance comparison cannot be made from measurements. The specification data alone indicates that the RTX PRO 4500 is the higher-performing part across all compute and graphics metrics. The Steam Deck GPU wins only in power draw and physical size, with no performance category in its favor.

Architecture Differences

The two GPUs use fundamentally different architectures from different generations. The AMD Steam Deck OLED GPU uses RDNA 2.0 with the Sephiroth chip, built on a 6 nm process at TSMC. The NVIDIA RTX PRO 4500 Blackwell Workstation uses Blackwell 2.0 with the GB203 chip, built on a 5 nm process, also at TSMC.

The transistor counts reflect the scale difference. The GB203 packs 45,600 million transistors on a 378 mm² die, while the Sephiroth chip contains 2,400 million transistors on a 131 mm² die. Transistor density is 120.6M per mm² for the Blackwell part versus 18.3M per mm² for the RDNA 2.0 part.

Clock speeds also differ. The RTX PRO 4500 has a base clock of 1,635 MHz and a boost clock of 2,407 MHz. The Steam Deck GPU has a base clock of 1,000 MHz and a boost clock of 1,600 MHz. Memory clocks are 1,750 MHz (28 Gbps effective) for the workstation card and 1,375 MHz (11 Gbps effective) for the Steam Deck GPU.

The compute pipelines are built differently. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The Steam Deck GPU has 512 shading units, 32 TMUs, 16 ROPs, and 8 RT cores, with no tensor cores. FP16 processing shows the architectural gap: the RTX PRO 4500 runs FP16 at 50.53 TFLOPS (1:1), while the Steam Deck GPU runs FP16 at 3.277 TFLOPS (2:1).

The RTX PRO 4500 uses a dual-slot design measuring 267 mm by 111 mm by 40 mm, with a 16-pin power connector and a 550 W suggested power supply. The Steam Deck GPU measures 298 mm by 117 mm by 49 mm, but its 15 W TDP requires no external power connector. The workstation card uses PCIe 5.0 x16, while the Steam Deck GPU has no bus interface listed.

API support is nearly identical, with both reaching DirectX 12 Ultimate (12_2) and OpenGL 4.6. Vulkan support favors the newer NVIDIA part at version 1.4 versus 1.3 for AMD. The RTX PRO 4500 was released on 2025-03-17, succeeding the Workstation Ada series, while the Steam Deck GPU was released on 2023-11-08. Both are listed as Active in production status.
