AMD Ryzen Z2 A GPU vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark results for the AMD Ryzen Z2 A GPU against the Intel Arc G3 Extreme. The head-to-head benchmark array is empty, and both products show zero wins in direct comparisons. Neither GPU has an average benchmark score entered into the database, and both sit at the 50th percentile against all GPUs. This means no measured performance delta can be derived from direct competition data. The absence of scores does not indicate equivalence; it simply reflects that no comparative workload results have been recorded for this pairing.

What the data does allow is a comparison of theoretical output rates, which are drawn directly from the specification fields. The Intel Arc G3 Extreme delivers a pixel rate of 60.00 GPixel/s, which is 2.34 times the 25.60 GPixel/s of the AMD Ryzen Z2 A GPU. In texture throughput, the Intel part reaches 120.0 GTexel/s against 51.20 GTexel/s for the AMD part, a factor of 2.34 as well. Floating-point performance shows a similar gap: the Intel Arc G3 Extreme computes 7.680 TFLOPS in FP32, compared with 1.638 TFLOPS for the AMD Ryzen Z2 A GPU. That is 4.69 times higher. In FP16, Intel delivers 15.36 TFLOPS (2:1) versus 3.277 TFLOPS (2:1) for AMD, again a 4.69 ratio. These are theoretical maxima, not measured application results, but they represent the only quantitative performance signals available in the database for this head-to-head.

Shader and fixed-function hardware scales in the same direction. The Intel Arc G3 Extreme carries 1536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. The AMD Ryzen Z2 A GPU carries 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The Intel part therefore has 3 times the shading units, 1.5 times the TMUs, 1.5 times the ROPs, and 1.5 times the ray tracing cores. Clock behavior also diverges sharply. The Intel GPU boosts to 2500 MHz from a 300 MHz base, while the AMD GPU boosts to 1600 MHz from a 1000 MHz base. The Intel boost clock is 1.56 times higher than the AMD boost clock. All of these figures come directly from the specification fields, and they consistently favor the Intel part on raw throughput.

The AMD Ryzen Z2 A GPU holds one structural advantage: memory configuration. It has 16 GB of LPDDR5 on a 128 bit bus, delivering 102.4 GB/s of bandwidth. The Intel Arc G3 Extreme uses system shared memory, with the bus width, type, and size all listed as system dependent. Its bandwidth is described as system dependent, meaning no fixed figure exists in the database. The AMD part's dedicated 16 GB allocation is a concrete number, whereas the Intel part's memory behavior cannot be quantified from the recorded data. This is the only category where the AMD product shows a clear, numeric edge over the Intel product.

The Verdict

The data points in one direction for compute-heavy workloads. The Intel Arc G3 Extreme has 4.69 times the FP32 throughput, 4.69 times the FP16 throughput, 2.34 times the pixel fill rate, and 2.34 times the texture fill rate of the AMD Ryzen Z2 A GPU. Its boost clock is 1.56 times higher, and its shader count is 3 times higher. Any application that scales with shading units, clock speed, or fill rate should favor the Intel part according to the recorded specifications. The database shows no benchmark scores to contradict this, since both products have an average benchmark score of 0 and no head-to-head entries.

The AMD Ryzen Z2 A GPU is the part for a fixed, local memory pool. Its 16 GB of LPDDR5 at 102.4 GB/s is fully specified, while the Intel part relies on system shared memory with no fixed bandwidth. The AMD GPU also consumes 15 W of power, compared with 80 W for the Intel GPU. That 65 W difference is the largest numeric gap in the power field. For scenarios where memory placement and power draw are the primary constraints, the AMD part has the recorded advantage. For scenarios where raw shader throughput and fill rate dominate, the Intel part is the clear choice from the data.

The verdict is therefore split by workload type. The Intel Arc G3 Extreme should be selected when the workload is compute-bound and fill-rate-bound, based on its 7.680 TFLOPS FP32 and 60.00 GPixel/s pixel rate. The AMD Ryzen Z2 A GPU should be selected when a dedicated 16 GB memory allocation and a 15 W power envelope are required, since the Intel part's memory is system dependent and its TDP is 80 W. Neither product has measured benchmark data in the database, so these conclusions rest entirely on the specification fields.

Architecture Differences

The two GPUs come from different manufacturers and different architectural generations. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0, produced by TSMC on a 7 nm process. The Intel Arc G3 Extreme uses the Panther Lake chip built on Xe3-LPG, produced by Intel on a 3 nm process. The process node gap is significant: 7 nm versus 3 nm. The AMD part is classified as a Console GPU (AMD) generation, while the Intel part is classified as Arc Graphics-M (Panther Lake) generation. The AMD chip contains 2,400 million transistors on a 163 mm² die, giving a transistor density of 14.7M / mm². The Intel chip has unknown transistor count, unknown die size, and no density figure in the database.

The AMD GPU uses a 128 bit memory bus with 16 GB of LPDDR5. The Intel GPU uses system shared memory with no fixed bus width. The Intel part is listed with a slot width of IGP and a bus interface of IGP, meaning it is an integrated graphics processor. The AMD part has no slot width, no bus interface, and no power connector information recorded. The Intel part has no power connectors listed, consistent with its IGP classification. The AMD part's display output is 1x USB Type-C, while the Intel part's display output is described as portable device dependent.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means API-level feature parity in the recorded data. The Intel part has 12 ray tracing cores against 8 for the AMD part, and both are listed without tensor cores. The AMD part's memory clock is 800 MHz with 6.4 Gbps effective, while the Intel part's memory clock is listed as system shared. The AMD part's architecture is RDNA 2.0, which is a previous-generation design from AMD, whereas the Intel part's Xe3-LPG is a newer architecture designation in the database.
