AMD Ryzen Z2 Go GPU vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either the AMD Ryzen Z2 Go GPU or the Intel Arc G3 Extreme. Both entries show an empty benchmark array, an average benchmark score of zero, and a percentile rank of 50 against all GPUs. Without measured performance data, direct head-to-head comparisons cannot be expressed as numerical deltas or percentage differences. What the database does provide are architectural and specification details that allow for a predictive analysis of relative performance, though no verified benchmark results exist to confirm those predictions.

The absence of benchmark data means that claims about which part is faster in specific workloads must be treated as projections based on hardware parameters, not as confirmed results. The AMD part operates at a base clock of 800 MHz with a boost of 2700 MHz, while the Intel part runs at a base of 300 MHz and boosts to 2500 MHz. Raw clock speed alone does not determine performance, as architectural efficiency and memory subsystem characteristics play substantial roles. The Intel Arc G3 Extreme carries 1536 shading units, exactly double the 768 shading units on the AMD Ryzen Z2 Go GPU. That doubling of shading units translates directly into the FP32 compute figures: 7.680 TFLOPS for Intel versus 4.147 TFLOPS for AMD, a 85.2% advantage for Intel in raw single-precision floating-point throughput. The FP16 figures follow the same pattern, with Intel at 15.36 TFLOPS and AMD at 8.294 TFLOPS, again a 2:1 ratio.

However, the AMD part counters with a higher pixel rate. The Ryzen Z2 Go GPU delivers 86.40 GPixel/s, while the Arc G3 Extreme delivers 60.00 GPixel/s. That is a 44% advantage for AMD in pixel throughput, which matters for fill-rate-bound scenarios at high resolutions. Texture rate favors Intel slightly: 129.6 GTexel/s for AMD versus 120.0 GTexel/s for Intel, a 8% lead for AMD in that specific metric. The two parts match on texture mapping units at 48 each, and both have 12 ray tracing cores. The ROP counts differ, with AMD at 32 and Intel at 24, which explains the pixel rate gap.

Architecture Differences

The two GPUs come from different architectural lineages entirely. The AMD Ryzen Z2 Go GPU is built on the Rembrandt+ chip, which uses the RDNA 2.0 architecture, a design originally developed for console-class graphics. The Intel Arc G3 Extreme uses the Panther Lake chip with the Xe3-LPG architecture, belonging to the Arc Graphics-M generation for Panther Lake platforms. These are fundamentally different design philosophies: RDNA 2.0 is a mature, proven architecture from AMD's console work, while Xe3-LPG represents Intel's integrated graphics evolution for mobile processors.

Manufacturing processes diverge substantially. AMD uses a 6 nm process at TSMC, with a die size of 208 mm² and 13,100 million transistors, yielding a transistor density of 63.0M per mm². Intel uses a 3 nm process at its own foundry, though the transistor count and die size are listed as unknown in the database. The smaller process node for Intel suggests a potential efficiency advantage, but without transistor data, that remains speculative. The AMD part's transistor density figure is recorded, while Intel's is null.

Ray tracing hardware exists on both parts, with each carrying 12 RT cores. This parity means neither GPU has a structural advantage in ray tracing workload capacity, though the Intel part's higher shading unit count may allow it to process ray tracing related compute tasks faster. Tensor cores are absent from both entries, so neither GPU has dedicated AI acceleration hardware recorded in the database.

The Intel part is classified as an IGP (integrated graphics processor), with its slot width listed as "IGP" and its bus interface also "IGP". This indicates it is designed to be integrated into a processor package rather than installed as a discrete card. The AMD part has no slot width, power connector, or bus interface data recorded, though it does list a power connector of "None" and a single display output of 1x USB Type-C. The Intel part's display outputs are described as "Portable Device Dependent", reflecting its mobile-oriented design.

Specification Differences

The specification table shows several clear divergences between the two parts. The AMD Ryzen Z2 Go GPU uses 768 shading units, while the Intel Arc G3 Extreme uses 1536, exactly double. Both have 48 texture mapping units, so that metric matches. ROP counts differ: 32 for AMD versus 24 for Intel. Both have 12 ray tracing cores. FP32 compute is 4.147 TFLOPS for AMD and 7.680 TFLOPS for Intel. FP16 compute is 8.294 TFLOPS for AMD and 15.36 TFLOPS for Intel, with both using a 2:1 ratio.

Memory specifications are radically different. AMD has a fixed 16 GB of LPDDR5 on a 128-bit bus with 102.4 GB/s bandwidth. Intel uses system shared memory with system dependent bandwidth, meaning its performance scales with the host platform's memory configuration. The AMD memory clock is listed as 800 MHz with 6.4 Gbps effective, while Intel's memory clock is "System Shared" with no fixed value.

Clock speeds favor AMD in both base and boost: 800 MHz base and 2700 MHz boost versus Intel's 300 MHz base and 2500 MHz boost. Pixel rate favors AMD at 86.40 GPixel/s versus Intel's 60.00 GPixel/s. Texture rate slightly favors AMD at 129.6 GTexel/s versus Intel's 120.0 GTexel/s. TDP differs by a wide margin: 28 W for AMD versus 80 W for Intel. Both have no power connectors, but the Intel part is an IGP while the AMD part has no form factor classification recorded. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates that the Intel Arc G3 Extreme is the stronger compute performer by a significant margin. Its 7.680 TFLOPS FP32 output is nearly double the AMD Ryzen Z2 Go GPU's 4.147 TFLOPS, which suggests substantially better performance in compute-heavy workloads such as shader processing, physics simulation, and general graphics rendering. The doubled shading unit count provides a structural basis for this advantage. For users who prioritize raw processing power, the Intel part appears superior based on the recorded specifications.

The AMD Ryzen Z2 Go GPU, however, has clear advantages in specific areas. Its 44% higher pixel rate, driven by a higher ROP count, suggests better performance in fill-rate-bound scenarios. Its 28 W TDP is dramatically lower than Intel's 80 W, indicating that AMD designed this part for power-constrained environments. The 16 GB of dedicated LPDDR5 memory with 102.4 GB/s bandwidth is a fixed, guaranteed resource, whereas the Intel part depends on system memory that may or may not match that bandwidth depending on the host platform.

The absence of benchmark data in the database means that neither part can be declared a definitive winner in real-world testing. The specification sheet points toward Intel for compute throughput and AMD for efficiency and fixed memory allocation. The Intel part's 3 nm process and IGP classification suggest it belongs in a newer, more integrated platform, while the AMD part's 6 nm process and discrete-style memory configuration indicate a different design target. Both parts sit at the 50th percentile against all GPUs, which is the default value for entries without benchmark data, so no comparative standing can be inferred from that field.

Where Each One Wins

The Intel Arc G3 Extreme wins in scenarios that demand high shader throughput. Its 1536 shading units and 7.680 TFLOPS FP32 provide the compute headroom needed for modern game rendering, which increasingly relies on complex shader programs and compute-based effects. The 15.36 TFLOPS FP16 output supports workloads that can utilize half-precision arithmetic, such as certain post-processing effects and machine learning inference tasks. The 3 nm process node also suggests that Intel targeted a design where power efficiency per transistor is a priority, though the 80 W TDP indicates the overall package consumes more power than the AMD part.

The AMD Ryzen Z2 Go GPU wins in power-sensitive applications. Its 28 W TDP is less than half of Intel's 80 W, making it suitable for passively cooled devices or systems with strict thermal budgets. The 16 GB of fixed LPDDR5 memory means that memory performance is consistent and predictable, unlike the Intel part's system dependent bandwidth. The 86.40 GPixel/s pixel rate gives AMD an edge in resolution scaling and fill-rate-heavy workloads such as high-detail texture rendering at lower compute requirements. The 129.6 GTexel/s texture rate also slightly exceeds Intel's 120.0 GTexel/s, which benefits games that rely heavily on texture sampling.

For ray tracing, both parts have 12 RT cores, so neither has a structural advantage in that specific subsystem. The Intel part's higher overall compute could translate to faster ray tracing in practice, but the database does not contain benchmark results to confirm such an outcome. The AMD part's higher boost clock of 2700 MHz versus 2500 MHz may help in lightly threaded or clock-sensitive workloads, but the shading unit deficit limits its ceiling.

The decision between the two comes down to the intended use case. The Intel Arc G3 Extreme is positioned for users who need maximum compute throughput in an integrated form factor and can accommodate its 80 W power draw. The AMD Ryzen Z2 Go GPU is positioned for users who need a fixed 16 GB memory allocation, lower power consumption, and higher pixel throughput, accepting lower raw compute in exchange. Neither part has recorded benchmark scores, so these conclusions derive entirely from the specification differences documented in the database.
