AMD Ryzen Z2 Go GPU vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 Go GPU and the NVIDIA RTX PRO 4500 Blackwell. The AMD part has no benchmark entries, while the NVIDIA card has nine recorded tests. This absence of overlapping data means the comparison rests on the NVIDIA card's measured results and the architectural specifications of both parts.

The NVIDIA RTX PRO 4500 Blackwell delivers a 3DMark Steel Nomad DX12 score of 7025. Its Geekbench Vulkan result reaches 221768, which indicates strong compute and graphics throughput in cross-platform workloads. The Passmark suite shows a G3D score of 33360 and a GPU compute score of 19255. These numbers place the card at the 76th percentile among all GPUs in the database, with an average benchmark score of 31532.

The nearest rivals for the NVIDIA card provide context. The NVIDIA TITAN RTX scores 31676, which is 0.5% higher than the RTX PRO 4500's average. The NVIDIA GRID M60-1Q and NVIDIA Quadro M5000 both score 31220 and 31206 respectively, each 1% lower. The Intel Arc Pro A30M scores 31894, 1.1% higher. The RTX PRO 4500 sits within a tight competitive band, with all nearest rivals within roughly one percentage point of its average score.

For the AMD Ryzen Z2 Go GPU, the absence of benchmark data means no direct wins can be recorded. The wins tally shows zero for both parts in head-to-head tests. The analysis therefore depends on the documented specifications and the NVIDIA card's standalone performance results.

Architecture Differences

The two GPUs come from different architectural generations. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, built on a 6 nm process at TSMC. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip with Blackwell 2.0 architecture, also from TSMC but on a 5 nm node. The fabrication differences are substantial. The AMD chip contains 13,100 million transistors on a 208 mm² die, yielding a density of 63.0 million transistors per square millimeter. The NVIDIA chip packs 45,600 million transistors into a 378 mm² die, achieving 120.6 million per square millimeter.

The transistor counts and densities reflect fundamentally different design priorities. The AMD part is a compact, low-power console GPU, while the NVIDIA card is a professional workstation GPU with far more compute resources. The Blackwell 2.0 architecture introduces a different feature set. The RTX PRO 4500 includes 82 ray tracing cores and 328 tensor cores, alongside 10,496 shading units. The AMD Ryzen Z2 Go GPU has 12 ray tracing cores and no tensor cores, with 768 shading units. The shading unit count alone indicates a 13.7x difference in raw shader hardware.

Memory architecture also diverges sharply. The AMD GPU uses 16 GB of LPDDR5 memory on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The NVIDIA card uses 32 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s. That is an 8.75x bandwidth advantage. The memory clock rates differ as well, with the AMD part running at 800 MHz (6.4 Gbps effective) and the NVIDIA part at 1750 MHz (28 Gbps effective). The NVIDIA card's memory subsystem is clearly designed for data-intensive professional workloads.

Compute throughput tells a similar story. The AMD Ryzen Z2 Go GPU delivers 4.147 TFLOPS of FP32 performance and 8.294 TFLOPS of FP16 performance using a 2:1 ratio. The NVIDIA RTX PRO 4500 Blackwell delivers 50.53 TFLOPS for both FP32 and FP16, with a 1:1 ratio. The NVIDIA card offers 12.2x the FP32 throughput and 6.1x the FP16 throughput. Pixel and texture rates follow the same pattern. The AMD part reaches 86.40 GPixel/s and 129.6 GTexel/s, while the NVIDIA card reaches 269.6 GPixel/s and 789.5 GTexel/s.

The power envelopes differ correspondingly. The AMD Ryzen Z2 Go GPU has a TDP of 28 W and requires no power connectors. The NVIDIA RTX PRO 4500 Blackwell has a TDP of 200 W, uses a single 16-pin connector, and recommends a 550 W power supply. The AMD part is a single-slot or compact design with one USB Type-C display output, while the NVIDIA card is dual-slot, measures 267 mm in length, 111 mm in height, and 40 mm in width, and provides four DisplayPort 2.1b outputs.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card uses a PCIe 5.0 x16 bus interface, while the AMD part has no recorded bus interface in the database. The NVIDIA card's predecessor is listed as Workstation Ada, and its production status is active. The AMD part is also active, with a release date of December 31, 2024, while the NVIDIA card released on March 17, 2025.

The Verdict

The data shows two GPUs with entirely different purposes. The AMD Ryzen Z2 Go GPU is a low-power console GPU with modest compute resources, designed for efficiency and compact integration. The NVIDIA RTX PRO 4500 Blackwell is a professional workstation card with massive compute throughput, large memory capacity, and high bandwidth.

For workloads that demand raw performance, the NVIDIA card is the clear choice. Its 50.53 TFLOPS of FP32 performance dwarfs the AMD part's 4.147 TFLOPS. Its 896.0 GB/s of memory bandwidth and 32 GB of GDDR7 memory support large datasets and complex scenes. The 82 ray tracing cores and 328 tensor cores provide dedicated hardware for ray-traced rendering and AI-accelerated tasks. The 76th percentile ranking and average benchmark score of 31532 confirm its position in the upper tier of GPUs.

For workloads that prioritize power efficiency and minimal footprint, the AMD part has advantages. Its 28 W TDP is 7.1x lower than the NVIDIA card's 200 W. It requires no power connectors and uses a single USB Type-C display output, which suits compact or mobile designs. The RDNA 2.0 architecture with 12 ray tracing cores still supports modern graphics features, including DirectX 12 Ultimate.

The specification differences are so large that these GPUs are unlikely to compete in the same systems. The AMD part fits into low-power consoles or handheld devices. The NVIDIA card requires a dual-slot chassis, a 550 W power supply, and a PCIe 5.0 x16 slot. The choice depends entirely on the target platform and workload. The database shows no direct benchmark comparisons, so the verdict rests on the architectural and performance specifications alone.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in power efficiency. Its 28 W TDP is dramatically lower than the NVIDIA card's 200 W, and it needs no external power connectors. This makes it suitable for compact, low-power systems such as handheld consoles. The single USB Type-C display output also simplifies integration. Its 16 GB of LPDDR5 memory is ample for console-class workloads, and the 6 nm process node keeps the die compact at 208 mm².

The NVIDIA RTX PRO 4500 Blackwell wins in every performance category. Its FP32 throughput of 50.53 TFLOPS is 12.2x higher. Its memory bandwidth of 896.0 GB/s is 8.75x higher. Its 32 GB of GDDR7 memory doubles the AMD part's capacity. The 328 tensor cores provide dedicated AI acceleration, and the 82 ray tracing cores handle complex ray-traced scenes. The 269.6 GPixel/s pixel rate and 789.5 GTexel/s texture rate support high-resolution, high-detail rendering. The four DisplayPort 2.1b outputs enable multi-display professional setups.

The benchmark record reinforces the NVIDIA card's position. Its 76th percentile ranking and average score of 31532 place it in the upper tier of the database. The AMD part has no recorded benchmarks, so its percentile of 50 is a default value rather than a measured result. For any workload that requires maximum compute, memory, or rendering capability, the NVIDIA RTX PRO 4500 Blackwell is the appropriate choice. For any workload that demands minimal power draw and a small footprint, the AMD Ryzen Z2 Go GPU fits that role. The two GPUs serve different markets, and the data confirms that the performance gap is substantial in every measurable specification.
