AMD Ryzen Z2 GPU vs NVIDIA RTX PRO 4000 Blackwell SFF Comparison

Head-to-Head Benchmarks

The recorded database does not contain any head-to-head benchmark entries for the AMD Ryzen Z2 GPU and the NVIDIA RTX PRO 4000 Blackwell SFF. This means there are no direct comparison scores in the 3DMark Steel Nomad DX12 test or any other shared workload. The AMD Ryzen Z2 GPU has no benchmark scores listed at all, while the NVIDIA RTX PRO 4000 Blackwell SFF has a single recorded score of 2910 in 3dmark_3dmark_steel_nomad_dx12.

The absence of direct comparison data is significant. Without a shared test, the only quantitative anchor comes from the NVIDIA card's nearest rivals. The RTX PRO 4000 Blackwell SFF scores 2910, which places it 0.1% ahead of the NVIDIA GeForce RTX 4060 Ti 16 GB (avg score 2907), and 0.1% behind the NVIDIA GeForce RTX 4060 Ti 8 GB (avg score 2913). It trails the NVIDIA Quadro P600 by 0.4% (avg score 2923) and leads the NVIDIA GeForce RTX 4010 by 0.6% (avg score 2893). These deltas are all within one percentage point, indicating the RTX PRO 4000 Blackwell SFF sits in a very tight performance cluster.

For the AMD Ryzen Z2 GPU, the database records zero benchmark scores and zero nearest rivals. Its percentileVsAllGpus field is 50, which is the median position across all GPUs in the database, but this percentile is not tied to any actual measured workload. The NVIDIA card, by contrast, carries a percentileVsAllGpus of 19, meaning it ranks below the median but its actual score is anchored to a real test. The data indicates that the AMD part's percentile is a placeholder rather than a derived measurement.

The practical implication is straightforward: any claim about which GPU is faster in a specific game or synthetic test cannot be supported by the recorded measurements. What the data does show is the NVIDIA card's performance envelope relative to its known rivals, and the AMD card's complete lack of benchmark presence. This asymmetry forces the analysis to rely on architectural and specification differences rather than direct scores.

Where Each One Wins

Without head-to-head benchmarks, the wins must be inferred from the specification sheet and the one available score. The NVIDIA RTX PRO 4000 Blackwell SFF wins on raw compute throughput. Its FP32 rating of 24.05 TFLOPS dwarfs the AMD Ryzen Z2 GPU's 8.294 TFLOPS, a difference of roughly 190% in favor of NVIDIA. The same ratio applies to FP16, where both cards operate at a 1:1 ratio with FP32, so NVIDIA again leads with 24.05 TFLOPS versus 8.294 TFLOPS.

Memory bandwidth is another decisive NVIDIA advantage. The RTX PRO 4000 Blackwell SFF delivers 432.0 GB/s over a 192-bit bus with 24 GB of GDDR7 memory. The AMD part offers 119.9 GB/s over a 128-bit bus with 16 GB of LPDDR5X. That is a 3.6x bandwidth gap, which matters for texture-heavy workloads, ray tracing acceleration, and large dataset processing. The NVIDIA card also has 24 GB versus 16 GB of memory capacity, giving it a 50% capacity advantage.

Pixel and texture throughput follow the same pattern. The NVIDIA card achieves 128.8 GPixel/s and 375.8 GTexel/s, while the AMD card manages 86.40 GPixel/s and 129.6 GTexel/s. NVIDIA leads by 49% in pixel rate and by 190% in texture rate. The AMD card's only clear win is in power efficiency on a pure wattage basis, with a 28 W TDP versus 70 W for the NVIDIA card, but this is not a benchmark win in the traditional sense.

The AMD Ryzen Z2 GPU does hold a transistor density advantage. It packs 25,390 million transistors into a 178 mm² die for a density of 142.6M per mm², while the NVIDIA chip uses 45,600 million transistors across 378 mm² for 120.6M per mm². This indicates AMD's 4 nm process achieves tighter packing than NVIDIA's 5 nm process, though the NVIDIA chip still has nearly 80% more total transistors.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Ryzen Z2 GPU uses the Hawk Point chip with RDNA 3.0 architecture, built on TSMC's 4 nm process. It is classified as a Console GPU in the AMD generation lineup. The NVIDIA RTX PRO 4000 Blackwell SFF uses the GB203 chip with Blackwell 2.0 architecture, built on TSMC's 5 nm process, and belongs to the Blackwell PRO W (x000) generation for workstation products.

Transistor counts differ substantially. The AMD chip contains 25,390 million transistors on a 178 mm² die, while the NVIDIA chip contains 45,600 million transistors on a 378 mm² die. The AMD die is smaller in absolute terms but denser per square millimeter, as noted earlier. The NVIDIA die is more than double the physical size and carries nearly double the transistor budget.

Compute unit organization diverges sharply. The AMD GPU has 768 shading units, 48 texture mapping units, and 32 raster output units. The NVIDIA GPU has 8960 shading units, 280 TMUs, and 96 ROPs. NVIDIA's shading unit count is 11.7x higher, and its TMU count is 5.8x higher. The ROP count is 3x higher on NVIDIA. These are massive architectural differences that directly explain the compute throughput gap.

Ray tracing hardware also differs. The AMD card includes 12 RT cores, while the NVIDIA card includes 70 RT cores. NVIDIA also adds 280 tensor cores, a feature completely absent from the AMD specification sheet. The tensor cores are relevant for AI and machine learning workloads, which the AMD part cannot accelerate with dedicated hardware.

Memory technology separates the two further. The AMD card uses LPDDR5X at 937 MHz (7.5 Gbps effective), while the NVIDIA card uses GDDR7 at 1125 MHz (18 Gbps effective). The NVIDIA memory clock is 20% higher in raw MHz but the effective data rate is 2.4x higher, and the bus width is 192-bit versus 128-bit. The NVIDIA card also has a PCIe 5.0 x8 bus interface, while the AMD card lists no bus interface at all.

Clock behavior is unusual. The AMD card has a base clock of 800 MHz and a boost of 2700 MHz, while the NVIDIA card has a base of 405 MHz and a boost of 1342 MHz. The AMD boost clock is more than double the NVIDIA boost. However, the NVIDIA architecture compensates with far more parallel units, so the lower clock still results in much higher aggregate throughput. The NVIDIA card's base clock of 405 MHz is notably low, suggesting aggressive power management at idle.

Physical and power characteristics differ as well. The NVIDIA card is a dual-slot design measuring 167 mm in length, 69 mm in height, and 40 mm in width, with a suggested PSU of 250 W. The AMD card has no listed dimensions, no slot width, and no suggested PSU. Both cards use no external power connectors, but the NVIDIA card has a 70 W TDP versus 28 W for the AMD card.

Display outputs also diverge. The AMD card provides a single USB Type-C output, while the NVIDIA card provides four mini-DisplayPort 2.1b outputs. This suggests the AMD card targets embedded or console-style use, while the NVIDIA card is built for multi-monitor workstation setups.

The Verdict

The recorded data offers no direct performance comparison between these two GPUs. The AMD Ryzen Z2 GPU has zero benchmark scores, while the NVIDIA RTX PRO 4000 Blackwell SFF has exactly one score. Any verdict must therefore rest on specifications and the NVIDIA card's proximity to its known rivals.

For users prioritizing raw compute, memory bandwidth, or ray tracing, the NVIDIA RTX PRO 4000 Blackwell SFF is the clear choice from the data. Its FP32 performance of 24.05 TFLOPS is 2.9x the AMD part's 8.294 TFLOPS. Its memory bandwidth of 432.0 GB/s is 3.6x higher. Its 70 RT cores versus 12 RT cores and 280 tensor cores versus none further widen the gap for specialized workloads. The NVIDIA card also has 24 GB of memory versus 16 GB, and its 4x mini-DisplayPort 2.1b outputs support more displays than the single USB Type-C on the AMD card.

The AMD Ryzen Z2 GPU wins on power consumption and transistor density. Its 28 W TDP is 40% of the NVIDIA card's 70 W TDP. Its 142.6M per mm² transistor density exceeds the NVIDIA card's 120.6M per mm². The AMD card also has a much higher boost clock at 2700 MHz versus 1342 MHz, though this does not translate into higher throughput given the massive unit count disadvantage.

The NVIDIA card's single benchmark score of 2910 places it within 0.6% of four different rival GPUs, all clustered between 2893 and 2923. This indicates the RTX PRO 4000 Blackwell SFF performs at the level of a mid-range GeForce card in that specific DX12 test, despite its workstation positioning. The AMD card has no comparable anchor, so its actual gaming or compute performance cannot be assessed from the database.

The production status for both is Active, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card was released on 2024-12-31, while the NVIDIA card followed on 2025-08-10. The NVIDIA card's predecessor is listed as Workstation Ada, while the AMD card has no predecessor or successor listed.

For pure performance per the recorded specifications, the NVIDIA RTX PRO 4000 Blackwell SFF is the only part with a measured score, and its architectural advantages are overwhelming. For power-constrained or density-focused applications, the AMD Ryzen Z2 GPU offers a 28 W envelope and a smaller, denser die. The choice depends entirely on whether the workload requires the NVIDIA card's compute and memory advantages or the AMD card's low-power profile.
