AMD Radeon RX 7800 XT vs AMD Ryzen Z2 Go GPU Comparison

Head-to-Head Benchmarks

The recorded database does not contain any shared benchmark tests between the AMD Radeon RX 7800 XT and the AMD Ryzen Z2 Go GPU. The head-to-head benchmark array is empty, and neither product has matched scores in any common test suite. This absence of direct comparative data is itself informative. The RX 7800 XT belongs to the Radeon RX 7000 series and carries a full set of benchmark results, while the Z2 Go GPU has no recorded benchmark scores at all, with an average benchmark score of zero.

The RX 7800 XT's individual results span multiple test suites. In 3DMark Steel Nomad DX12, it records 4157 points. Geekbench OpenCL shows 18290 points, while Geekbench Vulkan reaches 54228 points. Passmark results include DirectX 10 at 121 points, DirectX 11 at 249 points, DirectX 12 at 93 points, and DirectX 9 at 304 points. The G2D score is 1177, the G3D score is 24176, and GPU compute is 13473. Its average benchmark score across all recorded tests is 11627 points.

The Z2 Go GPU has no such measurements. Its percentile versus all GPUs is 50, while the RX 7800 XT sits at 51. The two are adjacent in the distribution, yet the Z2 Go's zero average score means its position in the percentile ranking is not supported by any actual benchmark runs in the database. The data gap prevents a direct head-to-head comparison. Any performance relationship between these two parts must be inferred from their architectural specifications rather than measured results.

Where Each One Wins

Without shared benchmarks, wins cannot be assigned by test scores. The wins array shows zero for both products. The RX 7800 XT, however, demonstrates capability through its recorded scores. Its Passmark G3D score of 24176 and Geekbench Vulkan score of 54228 indicate strong graphics processing. Its Passmark GPU compute score of 13473 suggests substantial compute throughput. The Z2 Go GPU offers no scores to place against these.

The RX 7800 XT's nearest rivals in the database provide context. Its average score of 11627 is 0.5% below the NVIDIA GeForce GTX 1660 at 11680, 0.9% above the AMD Radeon Pro 5500M at 11528, 1.3% above the NVIDIA Tesla K20c at 11479, and 1.8% below the AMD Radeon RX 6500 XT at 11842. These deltas position the RX 7800 XT in a narrow band around 11500 to 11800 points. The Z2 Go GPU has no rivals listed, so no similar relational data exists.

The use-case split emerges from specifications. The RX 7800 XT targets high-throughput environments: a rasterization rate of 233.3 GPixel/s, texture rate of 583.2 GTexel/s, and FP32 compute of 37.32 TFLOPS. The Z2 Go GPU delivers 86.40 GPixel/s, 129.6 GTexel/s, and 4.147 TFLOPS FP32, with FP16 at 8.294 TFLOPS. The RX 7800 XT's 263 W TDP and dual-slot design with two 8-pin connectors points to desktop or workstation use. The Z2 Go GPU's 28 W TDP, no power connectors, and single USB Type-C display output indicates a low-power, mobile or handheld form factor.

Architecture Differences

The two GPUs diverge sharply at the architecture level. The RX 7800 XT uses the Navi 32 chip built on RDNA 3.0, with the codename Wheat Nas, part of the Navi III (RX 7000) generation. The Z2 Go GPU uses the Rembrandt+ chip on RDNA 2.0, classified under Console GPU (AMD) generation. The process nodes differ: the RX 7800 XT is on 5 nm at TSMC, while the Z2 Go GPU is on 6 nm at the same foundry. Transistor counts reflect the scale gap. The RX 7800 XT packs 28,100 million transistors on a 346 mm² die, yielding a density of 81.2 million per mm². The Z2 Go GPU contains 13,100 million transistors on a 208 mm² die, with a density of 63.0 million per mm².

The memory subsystems are entirely different in type and bandwidth. The RX 7800 XT uses 16 GB of GDDR6 on a 256-bit bus, achieving 624.1 GB/s. The Z2 Go GPU also has 16 GB, but as LPDDR5 on a 128-bit bus, limiting bandwidth to 102.4 GB/s. Memory clocks reflect this: the RX 7800 XT runs at 2438 MHz with 19.5 Gbps effective, while the Z2 Go GPU runs at 800 MHz with 6.4 Gbps effective. The compute resources scale accordingly. The RX 7800 XT has 3840 shading units, 240 texture mapping units, 96 ROPs, and 60 ray tracing cores. The Z2 Go GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7800 XT offers FP32 and FP16 both at 37.32 TFLOPS with a 1:1 ratio; the Z2 Go GPU provides FP32 at 4.147 TFLOPS and FP16 at 8.294 TFLOPS with a 2:1 ratio. The RX 7800 XT has no tensor cores, and neither does the Z2 Go GPU.

Clock behavior also separates them. The RX 7800 XT has a base clock of 1295 MHz, a game clock of 2124 MHz, and a boost clock of 2430 MHz. The Z2 Go GPU has a base clock of 800 MHz and a boost of 2700 MHz, with no game clock listed. The higher boost on the Z2 Go GPU does not compensate for its far smaller execution resources. The RX 7800 XT uses PCIe 4.0 x16, while the Z2 Go GPU has no bus interface listed. Display outputs differ: the RX 7800 XT provides 1x HDMI 2.1a and 3x DisplayPort 2.1; the Z2 Go GPU provides only 1x USB Type-C.

The Verdict

The RX 7800 XT dominates in raw computational output. Its FP32 compute of 37.32 TFLOPS is nine times higher than the Z2 Go GPU's 4.147 TFLOPS. Memory bandwidth of 624.1 GB/s versus 102.4 GB/s shows a six-fold advantage. The RX 7800 XT's 3840 shading units, 240 TMUs, and 96 ROPs outclass the Z2 Go GPU's 768 shading units, 48 TMUs, and 32 ROPs. Its RT core count of 60 versus 12 indicates a much larger ray tracing workload capacity. The RX 7800 XT also carries a 5 nm process with 28,100 million transistors against the Z2 Go GPU's 6 nm process with 13,100 million.

The Z2 Go GPU holds advantages in power efficiency and boost clock. Its 28 W TDP versus 263 W means the Z2 Go GPU draws dramatically less power. Its boost clock of 2700 MHz exceeds the RX 7800 XT's 2430 MHz. The Z2 Go GPU has no power connectors and uses a single USB Type-C output, reflecting an integrated or embedded design. The RX 7800 XT requires 2x 8-pin connectors and a 600 W suggested PSU. The Z2 Go GPU's release date of 2024-12-31 is later than the RX 7800 XT's 2023-09-05, but no benchmark data exists for the Z2 Go GPU to validate its performance position.

The RX 7800 XT is the choice for workloads demanding high rasterization, texture throughput, and compute density. Its 233.3 GPixel/s pixel rate and 583.2 GTexel/s texture rate support heavy rendering tasks. The Z2 Go GPU, with 86.40 GPixel/s and 129.6 GTexel/s, suits constrained thermal environments where low power consumption matters more than peak throughput. The RX 7800 XT's 51 percentile versus all GPUs, supported by actual scores, contrasts with the Z2 Go GPU's 50 percentile based on no recorded benchmark runs. The data supports selecting the RX 7800 XT for performance-critical scenarios and the Z2 Go GPU for power-limited, compact implementations.
