AMD Ryzen Z2 Extreme GPU vs AMD Ryzen Z2 Go GPU Comparison

Head-to-Head Benchmarks

The recorded data offers only one direct benchmark score for the AMD Ryzen Z2 Extreme GPU. In the 3DMark Steel Nomad DX12 test, it achieves a score of 516. This places it in the 1st percentile of all GPUs in the database, indicating that the vast majority of recorded graphics processors outperform it. There are no benchmark entries for the AMD Ryzen Z2 Go GPU in the database, meaning its average benchmark score is recorded as 0 and its percentile ranking sits at 50, which is a default mid-range value rather than a measured performance result.

When examining the nearest rivals for the Z2 Extreme, the data shows a tight competitive cluster. The Intel HD Graphics P4000 posts an average score of 534, which is 3.4% higher than the Z2 Extreme's 516. The AMD Radeon HD 6870 scores 536, a 3.7% advantage. The AMD Radeon HD 6770M sits further ahead at 569, representing a 9.3% lead over the Z2 Extreme. Conversely, the AMD Radeon HD 6750M trails with a score of 484, meaning the Z2 Extreme is 6.6% faster than that particular rival. This places the Z2 Extreme in a narrow performance band, roughly between the HD 6750M below it and a group of three rivals above it.

Because the Z2 Go has no benchmark scores recorded, a direct head-to-head comparison via measured performance is impossible. The database does not list any head-to-head benchmark entries for these two products, and neither product registers a win in the winsA or winsB fields. The analysis must therefore rely on architectural specifications and the single available result for the Z2 Extreme.

Architecture Differences

The two GPUs diverge significantly in their underlying architecture and manufacturing process. The AMD Ryzen Z2 Extreme GPU uses the Strix Point chip, built on the RDNA 3.5 architecture, and is fabricated on a 4 nm process at TSMC. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip, based on the older RDNA 2.0 architecture, and is fabricated on a 6 nm process, also at TSMC. This generational gap in architecture and process node has direct implications for transistor density and efficiency.

The Z2 Extreme packs 34,000 million transistors onto a die size of 233 mm², resulting in a transistor density of 145.9 million transistors per square millimeter. The Z2 Go contains 13,100 million transistors on a slightly smaller die of 208 mm², yielding a density of just 63.0 million transistors per square millimeter. The Z2 Extreme therefore packs more than twice the transistor count into a modestly larger die, reflecting the density advantage of the 4 nm process over the 6 nm process.

Memory configurations also differ. Both GPUs ship with 16 GB of memory and a 128-bit bus width, but the Z2 Extreme uses LPDDR5X memory running at 1000 MHz with 8 Gbps effective speed, delivering 128.0 GB/s of bandwidth. The Z2 Go uses LPDDR5 memory at 800 MHz with 6.4 Gbps effective speed, resulting in 102.4 GB/s of bandwidth. The Z2 Extreme provides roughly 25% more memory bandwidth, which can matter in bandwidth-sensitive workloads.

The compute resources show a clear hierarchy. The Z2 Extreme has 1024 shading units, 64 texture mapping units (TMUs), 48 render output units (ROPs), and 16 ray tracing cores. The Z2 Go has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. These differences translate directly into rated throughput figures. The Z2 Extreme delivers 5.530 TFLOPS of FP32 performance and the same 5.530 TFLOPS of FP16 performance on a 1:1 ratio. The Z2 Go delivers 4.147 TFLOPS of FP32 performance but 8.294 TFLOPS of FP16 performance on a 2:1 ratio. The Z2 Extreme's FP16 throughput is lower than its FP32 rate would suggest for a 2:1 architecture, indicating a different ratio in its RDNA 3.5 design.

Pixel and texture rates follow the same pattern. The Z2 Extreme achieves 129.6 GPixel/s and 172.8 GTexel/s. The Z2 Go achieves 86.40 GPixel/s and 129.6 GTexel/s. The Z2 Extreme is roughly 50% faster in pixel fill rate and 33% faster in texture fill rate.

Both GPUs share the same 28 W TDP, have no power connectors, and output video through a single USB Type-C port. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active in production status. The release dates differ, with the Z2 Go released on December 31, 2024, and the Z2 Extreme released on July 8, 2025.

Where Each One Wins

The benchmark data does not provide a direct comparison between the two GPUs, so any assessment of relative strengths must draw from the architectural specifications. The Z2 Extreme holds advantages in nearly every measured compute and memory metric. Its FP32 throughput of 5.530 TFLOPS exceeds the Z2 Go's 4.147 TFLOPS by 33%. Its pixel rate of 129.6 GPixel/s exceeds the Z2 Go's 86.40 GPixel/s by 50%. Its texture rate of 172.8 GTexel/s exceeds the Z2 Go's 129.6 GTexel/s by 33%. Its memory bandwidth of 128.0 GB/s exceeds the Z2 Go's 102.4 GB/s by 25%.

The Z2 Go does hold one advantage: FP16 throughput. The Z2 Go's 8.294 TFLOPS of FP16 performance is 50% higher than the Z2 Extreme's 5.530 TFLOPS. This stems from the 2:1 FP16 ratio in the RDNA 2.0 architecture, whereas the Z2 Extreme operates at a 1:1 ratio. For workloads that can leverage FP16 arithmetic, the Z2 Go could theoretically process certain compute tasks faster, though this does not necessarily translate to gaming performance.

The Z2 Extreme also has more ray tracing cores (16 versus 12), which suggests better ray tracing workload capability. The Z2 Go's smaller transistor count and older architecture point to lower manufacturing complexity, but the database provides no efficiency or power delivery metrics beyond the shared 28 W TDP.

The Verdict

The data indicates that the AMD Ryzen Z2 Extreme GPU is the stronger performer on paper. It leads in shading units, TMUs, ROPs, ray tracing cores, FP32 throughput, pixel rate, texture rate, transistor density, and memory bandwidth. Its single recorded benchmark score of 516, while low in absolute terms at the 1st percentile, establishes a measurable performance baseline. The Z2 Go has no recorded benchmark score, so its actual performance in the database is unverified.

The Z2 Extreme's 33% lead in FP32 performance and 50% lead in pixel rate suggest it should handle traditional rasterized graphics workloads more effectively. Its 25% higher memory bandwidth supports higher resolution textures and more complex scenes. The Z2 Go's FP16 advantage is notable for compute-heavy tasks, but the lack of any recorded benchmark for the Z2 Go means the database cannot confirm whether that theoretical advantage translates into real-world wins.

For users selecting between these two, the Z2 Extreme is the choice when maximum graphics performance matters. The Z2 Go may appeal in scenarios where FP16 compute throughput is prioritized, but the absence of benchmark data makes it impossible to quantify its real-world standing. The Z2 Extreme also benefits from a newer architecture and a more advanced process node, both of which are reflected in its higher transistor density. Neither product has a launch MSRP recorded in the database.
