AMD Ryzen Z2 Go GPU vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 Go GPU and the NVIDIA RTX 4000 Ada Generation. However, the NVIDIA card has two benchmark scores in the database, while the AMD part has an average benchmark score of zero and no recorded tests. This absence of shared tests makes a direct numerical comparison impossible.

The NVIDIA RTX 4000 Ada Generation delivers a Geekbench OpenCL score of 146,593 and a Geekbench Vulkan score of 123,842. Its average benchmark score across all recorded tests is 135,218. The AMD Ryzen Z2 Go GPU has an average benchmark score of 0, which reflects the lack of any benchmark entries in the database, not a performance result of zero.

The NVIDIA card sits at the 95th percentile of all GPUs in the database, meaning it outperforms 95 percent of recorded graphics hardware. The AMD part sits at the 50th percentile, but that figure is derived from its position in the overall distribution, not from any measured benchmark run. The percentile gap of 45 points indicates a substantial difference in recorded standing, but the absence of AMD test data means the comparison relies on architectural specifications rather than measured results.

In terms of raw compute metrics from the specification data, the NVIDIA card has an FP32 throughput of 26.73 TFLOPS, while the AMD part has 4.147 TFLOPS. That represents a 6.4 times advantage for the NVIDIA card in single-precision floating-point performance. The NVIDIA card also leads in pixel rate at 139.2 GPixel/s versus 86.40 GPixel/s, a 1.6 times advantage, and in texture rate at 417.6 GTexel/s versus 129.6 GTexel/s, a 3.2 times advantage.

The AMD part counters in clock speed, with a boost clock of 2700 MHz compared to 2175 MHz for the NVIDIA card. That is a 24 percent higher boost clock for the AMD part. The AMD card also has a lower base clock of 800 MHz versus 1500 MHz for the NVIDIA card, so the AMD boost advantage does not translate into sustained performance across the entire clock curve.

Memory bandwidth shows a clear NVIDIA advantage: 360.0 GB/s versus 102.4 GB/s, a 3.5 times difference. The NVIDIA card also has more memory at 20 GB versus 16 GB, and a wider memory bus at 160 bit versus 128 bit.

Where Each One Wins

The NVIDIA RTX 4000 Ada Generation wins in every recorded compute and memory category. Its FP32 throughput of 26.73 TFLOPS is 6.4 times higher than the AMD part's 4.147 TFLOPS. Its FP16 throughput of 26.73 TFLOPS (1:1) matches its FP32 rate, whereas the AMD part achieves 8.294 TFLOPS at FP16 (2:1), meaning the NVIDIA card also leads in half-precision work by a factor of 3.2.

The NVIDIA card has 6,144 shading units, 192 texture mapping units, 64 render output units, 48 ray tracing cores, and 192 tensor cores. The AMD part has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores, with no tensor cores listed. The NVIDIA card's shading unit count is 8 times higher, its TMU count is 4 times higher, its ROP count is 2 times higher, and its ray tracing core count is 4 times higher.

The AMD part has no recorded benchmark wins. The wins count in the head-to-head section is 0 for AMD and 0 for NVIDIA, since no shared tests exist. The NVIDIA card's benchmark scores place it in the 95th percentile, while the AMD part sits at the 50th percentile, but the AMD percentile comes from its overall database position, not from measured performance.

The AMD part does have advantages in power efficiency. Its TDP is 28 W versus 130 W for the NVIDIA card, a 4.6 times lower power draw. The AMD part also uses no power connectors, while the NVIDIA card requires a single 16-pin connector and a suggested 300 W power supply. The AMD part's lower power envelope makes it suitable for constrained thermal environments, but the recorded data shows no performance benefit from that efficiency.

Architecture Differences

The NVIDIA chip has 2.7 times more transistors and 1.4 times the die area, with nearly double the transistor density.

Memory architecture differs completely. The AMD part uses 16 GB of LPDDR5 on a 128 bit bus, with memory clocked at 800 MHz (6.4 Gbps effective) and bandwidth of 102.4 GB/s. The NVIDIA card uses 20 GB of GDDR6 on a 160 bit bus, with memory clocked at 2250 MHz (18 Gbps effective) and bandwidth of 360.0 GB/s. The NVIDIA card has more memory, a wider bus, higher memory clock, and 3.5 times the bandwidth.

The NVIDIA card includes tensor cores, with 192 of them, which the AMD part does not list. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card has a PCIe 4.0 x16 bus interface, while the AMD part has no recorded bus interface. The NVIDIA card is single-slot with dimensions of 245 mm length and 112 mm height, while the AMD part has no recorded dimensions.

The NVIDIA card has four DisplayPort 1.4a outputs, while the AMD part has a single USB Type-C output.

The Verdict

The data points to the NVIDIA RTX 4000 Ada Generation as the superior performer across every recorded compute metric. Its FP32 throughput of 26.73 TFLOPS dwarfs the AMD part's 4.147 TFLOPS, its memory bandwidth of 360.0 GB/s is 3.5 times higher, and its 6,144 shading units outnumber the AMD part's 768 by a factor of 8. The NVIDIA card's 95th percentile standing in the database, supported by Geekbench OpenCL and Vulkan scores of 146,593 and 123,842 respectively, confirms its position among the top GPUs.

The AMD Ryzen Z2 Go GPU has no recorded benchmark scores, so its 50th percentile position reflects its database slot rather than measured performance. Its advantages are limited to boost clock (2700 MHz versus 2175 MHz) and power draw (28 W versus 130 W). The AMD part also has a lower transistor count (13,100 million versus 35,800 million) and a less dense chip (63.0 million per square millimeter versus 121.8 million).

For users prioritizing compute performance, memory bandwidth, ray tracing capability, or tensor core support, the NVIDIA card is the clear choice based on the recorded data. Its 48 ray tracing cores and 192 tensor cores provide features the AMD part cannot match. The NVIDIA card's 20 GB of memory also exceeds the AMD part's 16 GB, and its four DisplayPort outputs offer more display connectivity than the AMD part's single USB Type-C.

For users constrained by power or thermal limits, the AMD part's 28 W TDP and connector-free design present a lower-power alternative. The AMD part's higher boost clock may help in short, bursty workloads, but the NVIDIA card's higher base clock and superior compute resources make it the better choice for sustained performance.

The NVIDIA card's predecessor and successor relationships (Workstation Ampere before, Blackwell PRO W after) place it in a clear product lineage, while the AMD part has no recorded predecessor or successor. The release dates differ by roughly 16 months, with the NVIDIA card released on 2023-08-08 and the AMD part on 2024-12-31.
