Architecture Differences

The Radeon 760M is built on the RDNA 3.0 architecture, manufactured on a 4 nm process at TSMC. The chip is codenamed Phoenix and belongs to the Navi III IGP generation. It packs 25,390 million transistors into a 178 mm² die, resulting in a transistor density of 142.6 million transistors per square millimeter. The Ryzen Z2 A GPU, in contrast, uses the older RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. Its chip, codenamed Van Gogh, contains only 2,400 million transistors on a 163 mm² die, yielding a much lower transistor density of 14.7 million transistors per square millimeter.

Both GPUs share identical core configurations: 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The RDNA 3.0 implementation in the 760M, however, runs at significantly higher clocks. The base clock is 800 MHz with a boost clock of 2599 MHz. The RDNA 2.0 implementation in the Ryzen Z2 A GPU runs at a 1000 MHz base and 1600 MHz boost. This clock advantage, combined with the architectural improvements in RDNA 3.0, drives the large performance gap in raw throughput.

Memory architecture differs substantially. The Radeon 760M relies on system-shared memory, with bandwidth described as system dependent and no dedicated VRAM. The Ryzen Z2 A GPU has dedicated 16 GB of LPDDR5 memory on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The memory clock for the Z2 A is 800 MHz with 6.4 Gbps effective speed. The 760M's FP32 compute is 5.323 TFLOPS with FP16 at a 1:1 ratio, while the Z2 A GPU delivers 1.638 TFLOPS FP32 and 3.277 TFLOPS FP16 at a 2:1 ratio.

Pixel and texture rates follow the clock disparity. The Radeon 760M reaches 41.58 GPixel/s and 83.17 GTexel/s. The Ryzen Z2 A GPU achieves 25.60 GPixel/s and 51.20 GTexel/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 760M uses a PCIe 4.0 x8 interface, while the Z2 A has no specified bus interface in the database. Display outputs differ: the 760M is motherboard dependent (IGP), while the Z2 A has a single USB Type-C output.

The Verdict

The recorded data clearly separates these two GPUs by compute capability and memory strategy. The Radeon 760M delivers more than three times the FP32 performance of the Ryzen Z2 A GPU (5.323 TFLOPS versus 1.638 TFLOPS). Its boost clock is 62% higher (2599 MHz versus 1600 MHz). The 760M also carries a much larger transistor budget (25,390 million versus 2,400 million), reflecting a more complex and capable design.

The Ryzen Z2 A GPU, however, offers something the 760M lacks: dedicated memory. With 16 GB of LPDDR5 and 102.4 GB/s bandwidth, it does not depend on system memory allocation. This makes it suited for scenarios where predictable memory performance matters more than raw compute throughput.

The Radeon 760M sits at the 35th percentile among all GPUs in the database, with an average benchmark score of 6019. Its nearest rivals include the AMD Radeon RX 6400 (average score 6001, 0.3% higher) and the NVIDIA GeForce GTX 770M (average score 6000, 0.3% higher). The Ryzen Z2 A GPU has no recorded benchmarks and no average score, placing it at the 50th percentile by default.

For users who prioritize compute density, modern architecture, and higher frame rates in GPU-bound tasks, the Radeon 760M is the clear choice based on measured data. For those who need guaranteed memory bandwidth without relying on system RAM, the Ryzen Z2 A GPU offers a different trade-off. The data does not support a universal winner; it supports a split decision based on workload requirements.

Head-to-Head Benchmarks

The head-to-head benchmark data is empty, meaning no direct comparison scores exist between these two GPUs in the database. However, the individual benchmark results for the Radeon 760M provide a basis for analysis. The 760M scores 400 in 3DMark Steel Nomad DX12, 20255 in Geekbench OpenCL, and 30336 in Geekbench Vulkan. It also records 5310 in Passmark G3D, 2840 in Passmark GPU Compute, and 890 in Passmark G2D. DirectX-specific Passmark scores are 65 for DX9, 52 for DX11, 25 for DX12, and 19 for DX10.

The Ryzen Z2 A GPU has no recorded benchmarks, so direct numerical comparisons cannot be made. The absence of head-to-head results means the analysis relies on architectural specifications and measured performance of the 760M relative to its nearest rivals. The 760M's average benchmark score is 6019, placing it at the 35th percentile. Its closest competitor, the AMD Radeon RX 6400, scores 6001, a 0.3% difference. The NVIDIA GeForce GTX 770M scores 6000, also 0.3% higher. The NVIDIA RTX PRO 6000 Blackwell Server scores 5996, 0.4% higher. The NVIDIA Quadro P2000 scores 6049, which is 0.5% lower than the 760M.

These small delta percentages indicate the 760M sits in a tightly packed performance band. The data shows the 760M is essentially on par with the RX 6400 and GTX 770M, while slightly behind the Quadro P2000. The 0.5% gap to the Quadro P2000 is negligible in practical terms, but the consistency of these scores validates the 760M's position in the database ranking.

Where Each One Wins

The Radeon 760M wins decisively in raw compute performance. Its FP32 output of 5.323 TFLOPS is 3.25 times higher than the Z2 A's 1.638 TFLOPS. The boost clock advantage of 2599 MHz versus 1600 MHz translates directly to higher pixel and texture rates: 41.58 GPixel/s versus 25.60 GPixel/s, and 83.17 GTexel/s versus 51.20 GTexel/s. For any workload that is compute-bound, such as gaming at higher resolutions or GPGPU tasks, the 760M has a clear measured advantage.

The Ryzen Z2 A GPU wins on memory autonomy. Its dedicated 16 GB of LPDDR5 memory with 102.4 GB/s bandwidth does not compete with other system components for memory resources. The 760M's system-shared memory is system dependent, meaning performance can vary based on the host platform's memory configuration. For scenarios where memory allocation is unpredictable or where the system RAM is slow, the Z2 A provides consistent bandwidth.

The Z2 A also has a higher base clock (1000 MHz versus 800 MHz), which may indicate better efficiency at idle or low-load states, though the TDP for both is 15 W. The Radeon 760M's transistor count (25,390 million versus 2,400 million) reflects a much more complex design, but the Z2 A's simpler 163 mm² die with 14.7M transistors per mm² may be easier to manufacture or integrate into constrained form factors.

The benchmark data shows the 760M has an average score of 6019 with rivals within 0.5% either way. The Z2 A has no benchmark scores, so its competitive position is unknown. For users who want measured performance, the 760M is the only one with data. For users who need predictable memory bandwidth without system dependencies, the Z2 A's specifications support that use case. The data does not favor one across all metrics; it favors the 760M for compute throughput and the Z2 A for memory consistency.
