AMD Ryzen Z2 A GPU vs NVIDIA Jetson T4000 Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for either the AMD Ryzen Z2 A GPU or the NVIDIA Jetson T4000. Both entries hold equal percentile positions at 50, and both show an average benchmark score of zero. With no head-to-head benchmark results available, the comparison must focus on the raw specification data and what those specifications indicate about expected performance.

The most significant numerical gap appears in raw compute throughput. The NVIDIA Jetson T4000 delivers 4.700 TFLOPS of FP32 performance, while the AMD Ryzen Z2 A GPU produces 1.638 TFLOPS. This places the NVIDIA part at approximately 2.9 times the FP32 throughput of the AMD part. The FP16 comparison shows a similar pattern: the Jetson T4000 maintains 4.700 TFLOPS at a 1:1 ratio, while the Ryzen Z2 A GPU reaches 3.277 TFLOPS at a 2:1 ratio. The Jetson T4000 holds a clear lead in both precision formats.

Memory bandwidth also favors the NVIDIA part substantially. The Jetson T4000 provides 273.2 GB/s across a 256-bit LPDDR5X interface, compared to 102.4 GB/s on the Ryzen Z2 A GPU's 128-bit LPDDR5 bus. This 2.7 times bandwidth advantage suggests the NVIDIA part can feed its larger compute array more effectively in bandwidth-intensive workloads.

Texture throughput tells a similar story. The Jetson T4000 processes 73.44 GTexel/s against 51.20 GTexel/s for the Ryzen Z2 A GPU. The pixel rate, however, is nearly identical: 25.60 GPixel/s for the AMD part versus 24.48 GPixel/s for the NVIDIA part, a marginal difference of just over one gigapixel per second in favor of AMD.

The NVIDIA part's clock strategy emphasizes sustained operation. Both base and boost clocks sit at 1530 MHz, indicating a fixed clock profile. The AMD part runs at 1000 MHz base and boosts to 1600 MHz, a 60 percent boost headroom. This suggests the AMD part may have more variable performance depending on thermal headroom, while the NVIDIA part maintains consistent throughput.

Architecture Differences

The two processors come from different architectural generations and target different market segments. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. It belongs to the Console GPU (AMD) generation. The NVIDIA Jetson T4000 uses the GB10B chip built on Blackwell architecture, fabricated on TSMC's 5 nm process, and belongs to the Server Blackwell (Bxx) generation.

The process node difference is meaningful: 7 nm versus 5 nm. The AMD part integrates 2,400 million transistors on a 163 mm² die, producing a transistor density of 14.7 million transistors per square millimeter. The NVIDIA part's transistor count is listed as unknown, but its die size is 391 mm², more than twice the area of the AMD chip.

Core configuration differs substantially. The Ryzen Z2 A GPU contains 512 shading units, 32 texture mapping units, 16 raster operation units, and 8 ray tracing cores. The Jetson T4000 contains 1536 shading units, 48 texture mapping units, 16 raster operation units, 12 ray tracing cores, and 64 tensor cores. The NVIDIA part has three times the shading units, one and a half times the texture units, and one and a half times the ray tracing cores. The tensor core count of 64 gives the NVIDIA part dedicated AI acceleration hardware that the AMD part lacks entirely.

Memory architecture shows fundamental differences. The AMD part uses 16 GB of LPDDR5 across a 128-bit bus. The NVIDIA part uses 64 GB of LPDDR5X across a 256-bit bus. Memory clock rates also differ: 800 MHz with 6.4 Gbps effective for AMD, 1067 MHz with 8.5 Gbps effective for NVIDIA. The combination of wider bus, faster memory type, and higher clock rate produces the bandwidth advantage noted earlier.

Power envelopes differ dramatically. The AMD part carries a 15 W TDP, while the NVIDIA part consumes 90 W. This sixfold difference in power budget explains much of the performance gap. The AMD part operates within an integrated, power-constrained context, while the NVIDIA part draws from a larger power allocation typical of server-class hardware.

The NVIDIA part includes a PCIe 5.0 x8 bus interface, while the AMD part lists no bus interface. Display output also differs: the AMD part provides one USB Type-C output, while the NVIDIA part provides no display outputs at all. The NVIDIA part lists a suggested PSU of 250 W and has no power connectors, indicating it draws power through its host system rather than requiring direct power connections. Its dimensions are 87 mm by 100 mm by 15 mm, and it is classified as an IGP form factor.

The API support picture is inverted. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented design where graphics APIs are not the primary interface. The NVIDIA part's predecessor is listed as Server Hopper and its successor as Server Rubin, placing it in a server product lineage. The AMD part lists no predecessor or successor.

Where Each One Wins

The AMD Ryzen Z2 A GPU claims victory in pixel fill rate, delivering 25.60 GPixel/s against 24.48 GPixel/s for the NVIDIA part. This marginal advantage, combined with the AMD part's display output capability through USB Type-C, positions it for graphics-oriented tasks where frame rendering and display connectivity matter. The AMD part also carries full graphics API support, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it suitable for consumer graphics workloads that require these interfaces. Its 15 W TDP allows operation in power-constrained environments where the 90 W NVIDIA part would be impractical.

The NVIDIA Jetson T4000 wins on nearly every other measurable specification. Its FP32 throughput of 4.700 TFLOPS is nearly three times the AMD part's 1.638 TFLOPS. FP16 performance of 4.700 TFLOPS at a 1:1 ratio exceeds the AMD part's 3.277 TFLOPS at a 2:1 ratio, meaning the NVIDIA part maintains full throughput at half precision without the 2:1 penalty. The 64 GB memory capacity is four times the AMD part's 16 GB, and the 273.2 GB/s bandwidth is more than double. The 64 tensor cores provide dedicated AI acceleration absent from the AMD part. Texture rate of 73.44 GTexel/s exceeds the AMD part by roughly 43 percent. The PCIe 5.0 x8 interface enables high-speed host connectivity. The 5 nm process node and larger die size of 391 mm² indicate a more complex, capable silicon design.

The NVIDIA part's server classification, lack of display outputs, and absence of graphics API support indicate its purpose as a compute-focused accelerator rather than a graphics card. The AMD part's console classification, display output, and full graphics API stack indicate its purpose as an integrated graphics solution for consumer devices.

The Verdict

The data clearly separates these two processors into distinct usage categories. The AMD Ryzen Z2 A GPU operates as a low-power integrated graphics solution with a 15 W TDP, delivering 1.638 TFLOPS of FP32 performance, 16 GB of memory, and full support for consumer graphics APIs. Its sole numerical win is pixel rate, and it offers the practical advantage of display connectivity through USB Type-C.

The NVIDIA Jetson T4000 operates as a high-power compute accelerator with a 90 W TDP, delivering 4.700 TFLOPS of FP32 and FP16 performance, 64 GB of memory, 64 tensor cores, and server-focused specifications including PCIe 5.0 x8 connectivity and no display outputs. Its launch MSRP is 1,999 USD.

For workloads requiring graphics API compatibility, display output, and minimal power draw, the AMD Ryzen Z2 A GPU provides the necessary features. For workloads requiring maximum compute throughput, large memory capacity, high memory bandwidth, and dedicated tensor core acceleration, the NVIDIA Jetson T4000 is the stronger choice by a wide margin.

The performance gap is substantial and consistent across compute, memory, and texture metrics. The NVIDIA part's 2.9 times FP32 advantage, 2.7 times memory bandwidth advantage, and 64 tensor cores versus none make it the clear choice for compute-intensive applications. The AMD part's advantages are limited to pixel rate, graphics API support, display output, and power efficiency.

The production status of both parts is listed as Active, meaning both remain available. The NVIDIA part's predecessor and successor designations place it within an established server product line. The AMD part has no listed predecessor or successor, suggesting it may be a standalone integrated solution.

Selection between the two should follow the workload requirements. Graphics rendering with display output and low power consumption points to the AMD Ryzen Z2 A GPU. High-throughput compute, AI inference, and server deployment point to the NVIDIA Jetson T4000. The data does not support a single universal recommendation, as the two parts serve fundamentally different purposes with minimal overlap in their specification profiles.
