AMD Ryzen Z1 GPU vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen Z1 GPU and the NVIDIA RTX PRO 4500 Blackwell Server. With an empty `headToHeadBenchmarks` array, there are no recorded wins for either product in this pairing. Both products hold a percentile rank of 50 against all GPUs, indicating they sit at the median of the performance distribution, though this is based on separate benchmark pools rather than a shared test suite.

The absence of shared measurements means the FP32 compute figures, texture rates, and pixel throughput values in the database cannot be compared as direct test outcomes. The AMD Ryzen Z1 GPU records 2.560 TFLOPS FP32, while the NVIDIA RTX PRO 4500 records 50.70 TFLOPS FP32, but these are specification-derived values, not benchmark results. Similarly, the texture rate of 40.00 GTexel/s for the AMD part versus 792.1 GTexel/s for the NVIDIA part reflects theoretical peak capabilities, not measured application performance.

What the data does show is that both products target completely different performance envelopes. The AMD Ryzen Z1 GPU is positioned as a low-power console-class GPU, while the NVIDIA RTX PRO 4500 is a server-oriented Blackwell part. Without benchmark scores, any head-to-head comparison must rely on specification analysis, which the database does not support for direct claims of superiority in actual workloads.

Where Each One Wins

Since no benchmark wins are recorded, the use-case split must be inferred from the measured specifications. The AMD Ryzen Z1 GPU delivers its capabilities within a 30 W TDP, making it suitable for compact or power-constrained environments where thermal output is a primary constraint. Its 16 GB LPDDR5 memory on a 64-bit bus provides 51.20 GB/s bandwidth, which is modest but consistent with its low-power design.

The NVIDIA RTX PRO 4500 Blackwell Server uses 165 W with a single-slot form factor and a 1x 16-pin power connector, indicating it is built for dense server deployments where compute density matters more than absolute power efficiency. Its 32 GB GDDR7 memory on a 256-bit bus delivers 800.3 GB/s bandwidth, a figure that dwarfs the AMD part’s memory throughput by a factor of roughly 15.6.

The FP32 compute ratio is even more lopsided: 50.70 TFLOPS versus 2.560 TFLOPS, a 19.8x difference. The NVIDIA part also carries 328 tensor cores and 82 RT cores, while the AMD part lists 4 RT cores and no tensor core count. This specification split suggests the NVIDIA product is intended for AI inference, ray tracing, and high-throughput compute, while the AMD product is oriented toward basic graphics rendering in a low-power console context.

Specification Differences

The two GPUs differ across nearly every measured specification. The AMD Ryzen Z1 GPU uses a 4 nm process node, while the NVIDIA RTX PRO 4500 uses a 5 nm node, both from TSMC. The AMD chip, codenamed Phoenix, has 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The NVIDIA chip, GB203, has 45,600 million transistors on a 378 mm² die, with a lower density of 120.6M per mm².

Clock speeds differ: the AMD part has a base clock of 1500 MHz and a boost of 2500 MHz, while the NVIDIA part has a base of 1215 MHz and a boost of 2415 MHz. Memory clocks also diverge, with the AMD part at 800 MHz (6.4 Gbps effective) and the NVIDIA part at 1563 MHz (25 Gbps effective).

The memory subsystem is fundamentally different: 16 GB LPDDR5 on a 64-bit bus versus 32 GB GDDR7 on a 256-bit bus. The NVIDIA part also has a PCIe 5.0 x16 interface, while the AMD part has no bus interface listed. The NVIDIA part is single-slot with a 1x 16-pin power connector and a suggested PSU of 450 W, while the AMD part has no power connectors listed at all.

Physical dimensions differ: the AMD part measures 280 mm in length, 111 mm in height, and 21 mm in width. The NVIDIA part is 267 mm long, 111 mm high, and 40 mm wide, making it thicker. The AMD part has a launch MSRP of 599 USD, while no launch MSRP is recorded for the NVIDIA part.

Architecture Differences

The AMD Ryzen Z1 GPU is built on the RDNA 3.0 architecture, part of the Console GPU generation, while the NVIDIA RTX PRO 4500 uses Blackwell 2.0, part of the Server Blackwell generation. The AMD chip is named Phoenix, and the NVIDIA chip is named GB203.

The NVIDIA part includes 82 RT cores and 328 tensor cores, while the AMD part has only 4 RT cores and no tensor core count recorded. This indicates a significant divergence in hardware acceleration for ray tracing and AI workloads. The FP16 compute ratio also differs: the AMD part delivers 5.120 TFLOPS FP16 with a 2:1 ratio relative to FP32, while the NVIDIA part delivers 50.70 TFLOPS FP16 with a 1:1 ratio, meaning it does not rely on a half-rate path for FP16.

The NVIDIA part has a predecessor listed as Server Hopper and a successor as Server Rubin, indicating an established product lifecycle within the server segment. The AMD part has no predecessor or successor recorded. Both GPUs have no display outputs, reinforcing their non-consumer, compute-oriented positioning.

The production status for both is Active, with release dates of 2023-09-17 for the AMD part and 2026-03-16 for the NVIDIA part. The transistor counts reveal a design philosophy gap: the AMD part achieves higher density on a smaller die, while the NVIDIA part uses a larger die with more total transistors, enabling its higher compute and memory throughput.

The Verdict

The recorded data paints a clear picture of two products engineered for different purposes. The AMD Ryzen Z1 GPU, with its 30 W TDP, 2.560 TFLOPS FP32, and 51.20 GB/s memory bandwidth, is suited for low-power graphics tasks in embedded or console-style applications. Its 16 GB memory capacity is generous relative to its compute capability, but the narrow 64-bit bus limits sustained throughput.

The NVIDIA RTX PRO 4500 Blackwell Server, by contrast, is a high-throughput compute accelerator. Its 50.70 TFLOPS FP32, 328 tensor cores, 82 RT cores, and 800.3 GB/s memory bandwidth position it for AI training, ray-traced rendering, and large-scale data processing in server environments. The 165 W TDP and single-slot design indicate it is intended for dense multi-GPU racks where space is at a premium.

Neither product has benchmark scores in the database, so direct performance validation is unavailable. The specification deltas, however, are so large in favor of the NVIDIA part across compute, memory, and feature set that the choice depends entirely on the deployment context. The AMD part’s advantage lies in its lower power draw and smaller physical footprint. The NVIDIA part’s advantage lies in raw throughput and specialized hardware.

The release dates also matter: the AMD part launched in September 2023, while the NVIDIA part is dated March 2026, suggesting a newer design with more advanced features. For any workload requiring significant compute, tensor operations, or high memory bandwidth, the NVIDIA RTX PRO 4500 is the only viable option based on the recorded specifications. For minimal-power graphics output, the AMD Ryzen Z1 GPU offers a functional, low-cost alternative.
