Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs. The AMD Radeon 740M has recorded scores in two separate tests, while the AMD Ryzen Z2 Go GPU has no benchmark entries at all in the database. This makes a direct numerical comparison impossible based on measured performance data alone.

The Radeon 740M achieves a Geekbench OpenCL score of 10172 and a Geekbench Vulkan score of 15568. Its average benchmark score sits at 12870, which places it at the 53rd percentile among all GPUs tracked in the database. The Ryzen Z2 Go GPU carries a 50th percentile rating but has an average benchmark score of zero, reflecting the absence of recorded test results.

The Radeon 740M's nearest rivals in the database provide context for its standing. The AMD FirePro W5100 scores 12847, which is 0.2% behind the 740M. The AMD Radeon Pro 455 scores 12831, trailing by 0.3%. The NVIDIA GeForce GTX 590 also scores 12830, another 0.3% gap. On the other side, the AMD Radeon RX 580 scores 12928, putting it 0.4% ahead of the 740M. These deltas are remarkably tight, indicating the 740M sits in a dense cluster of similar-performing GPUs.

For the Ryzen Z2 Go GPU, the lack of benchmark data means no nearest rivals are listed and no percentile comparisons can be drawn. The data shows only its theoretical specifications, which cannot be validated against real-world test results at this time.

Architecture Differences

The two GPUs come from different architectural generations. The AMD Radeon 740M uses the Phoenix2 chip built on RDNA 3.0 architecture, categorized in the Navi III IGP (Phoenix) generation. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip based on RDNA 2.0 architecture, categorized as a Console GPU (AMD).

Manufacturing processes differ substantially. The 740M is fabricated on a 4 nm process at TSMC, while the Ryzen Z2 Go GPU uses a 6 nm process, also at TSMC. The transistor counts reflect this gap: the 740M packs 20,900 million transistors on a 137 mm² die, giving a transistor density of 152.6 million per mm². The Ryzen Z2 Go GPU contains 13,100 million transistors spread across a larger 208 mm² die, resulting in a much lower density of 63.0 million per mm².

Compute resources differ significantly. The Radeon 740M provides 256 shading units, 16 texture mapping units, and 8 render output units. The Ryzen Z2 Go GPU offers 768 shading units, 48 TMUs, and 32 ROPs. That is three times the shading units, three times the TMUs, and four times the ROPs. Ray tracing cores also differ: the 740M has 4, while the Ryzen Z2 Go GPU has 12.

Clock behavior shows a mixed picture. Both have an 800 MHz base clock. The 740M boosts to 2800 MHz, while the Ryzen Z2 Go GPU boosts to 2700 MHz. The 740M's higher boost clock does not fully compensate for its much smaller compute configuration.

Memory architecture is entirely different. The 740M uses system shared memory with a system-dependent bus width and bandwidth. The Ryzen Z2 Go GPU has dedicated 16 GB of LPDDR5 memory on a 128-bit bus, providing 102.4 GB/s of bandwidth. Its memory clock runs at 800 MHz with 6.4 Gbps effective data rate.

Pixel and texture throughput scales with the ROP and TMU counts. The 740M produces 22.40 GPixel/s and 44.80 GTexel/s. The Ryzen Z2 Go GPU produces 86.40 GPixel/s and 129.6 GTexel/s. These are 3.9 times and 2.9 times higher, respectively.

Floating-point performance follows the shading unit counts. The 740M delivers 2.867 TFLOPS FP32 and the same 2.867 TFLOPS FP16, indicating a 1:1 FP16 ratio. The Ryzen Z2 Go GPU delivers 4.147 TFLOPS FP32 and 8.294 TFLOPS FP16, using a 2:1 FP16 ratio. That gives the Ryzen Z2 Go GPU roughly 45% more FP32 throughput and 2.9 times the FP16 throughput.

Power consumption goes in the opposite direction. The 740M has a 45 W TDP, while the Ryzen Z2 Go GPU runs at 28 W. The Ryzen Z2 Go GPU delivers substantially more raw compute within a lower power envelope, though the 740M's process advantage and smaller die are relevant factors.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 740M uses a PCIe 4.0 x8 bus interface, while the Ryzen Z2 Go GPU has no bus interface listed. Display outputs differ: the 740M is motherboard dependent, and the Ryzen Z2 Go GPU provides 1x USB Type-C.

The Verdict

The recorded data points in opposite directions for these two GPUs. The Radeon 740M has actual benchmark results, placing it at the 53rd percentile with an average score of 12870. Its nearest rivals cluster within 0.4% on either side, indicating it performs in a well-established mid-range band. The Ryzen Z2 Go GPU has no benchmark data, an average score of zero, and a 50th percentile rating that appears provisional rather than measured.

For raw compute specifications, the Ryzen Z2 Go GPU holds clear advantages. Its 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores dwarf the 740M's 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The theoretical FP32 throughput of 4.147 TFLOPS versus 2.867 TFLOPS represents a 45% advantage. The dedicated 16 GB LPDDR5 memory with 102.4 GB/s bandwidth removes any dependency on system memory performance.

The 740M counters with architectural refinement. Its RDNA 3.0 design on a 4 nm process with 152.6 million transistors per mm² represents a much denser implementation than the RDNA 2.0 Ryzen Z2 Go GPU on 6 nm with 63.0 million transistors per mm². The 740M also boosts higher at 2800 MHz versus 2700 MHz.

The power situation complicates the choice. The Ryzen Z2 Go GPU delivers its specification advantage at 28 W, while the 740M draws 45 W. That means the Ryzen Z2 Go GPU provides more compute per watt on paper, though the 740M's actual measured performance in the database gives it a known quantity status.

For builders who require validated performance data, the Radeon 740M is the only option with recorded results. Its benchmark scores are real, its percentile ranking is established, and its rival comparisons are documented. For builders who prioritize maximum theoretical compute and dedicated memory, the Ryzen Z2 Go GPU presents the stronger specification sheet, but without benchmark confirmation.

The Radeon 740M suits systems where the motherboard provides display outputs and where system shared memory is acceptable. The Ryzen Z2 Go GPU suits compact designs with its single USB Type-C display output and integrated memory, but its performance remains unverified in the database.

Where Each One Wins

The Radeon 740M wins in measured benchmark validation. It has two recorded test scores, an average of 12870, and a 53rd percentile standing. The Ryzen Z2 Go GPU has zero benchmark entries, making its actual performance unknown. Any purchase decision involving the Ryzen Z2 Go GPU relies entirely on specification analysis rather than verified results.

The Radeon 740M also wins on manufacturing sophistication. The 4 nm process with 152.6 million transistors per mm² indicates a denser, more modern implementation. Its 2800 MHz boost clock is 100 MHz higher than the Ryzen Z2 Go GPU's 2700 MHz. The 740M also carries a known generation lineage as a Navi III IGP (Phoenix) part with a predecessor listed as Navi II IGP and a successor of Navi III IGP.

The Ryzen Z2 Go GPU wins decisively on raw compute specifications. Its 768 shading units deliver 4.147 TFLOPS FP32, which is 45% higher than the 740M's 2.867 TFLOPS. The FP16 advantage is even larger: 8.294 TFLOPS versus 2.867 TFLOPS, a factor of 2.9. The 48 TMUs and 32 ROPs translate to 129.6 GTexel/s and 86.40 GPixel/s, both roughly three to four times the 740M's rates. The 12 ray tracing cores triple the 740M's 4.

Memory is another clear win for the Ryzen Z2 Go GPU. The dedicated 16 GB LPDDR5 pool with 102.4 GB/s bandwidth and 128-bit bus provides predictable performance independent of system memory configuration. The 740M's system shared memory means bandwidth varies with the host platform.

Efficiency is a Ryzen Z2 Go GPU win. It delivers higher specifications at 28 W instead of 45 W, a 17 W difference. The lower TDP suggests suitability for power-constrained designs, though the 740M's process advantage partially offsets this in density terms.

For workloads relying on measured compatibility and verified performance, the Radeon 740M is the data-backed choice. For workloads demanding maximum shading throughput, texture fill, pixel fill, ray tracing capability, and dedicated memory bandwidth, the Ryzen Z2 Go GPU offers the stronger theoretical platform. The absence of benchmark data for the Ryzen Z2 Go GPU remains the single largest unknown in this comparison.
