AMD Ryzen Z2 Extreme GPU vs Intel Arc G3 Comparison

# AMD Ryzen Z2 Extreme GPU vs Intel Arc G3

The database comparison between the AMD Ryzen Z2 Extreme GPU and the Intel Arc G3 presents an unusual matchup: the AMD part is a standalone mobile-class GPU with a recorded benchmark score, while the Intel Arc G3 is an integrated graphics processor (IGP) with no benchmark entries yet. The AMD Ryzen Z2 Extreme GPU, built on the Strix Point chip with RDNA 3.5 architecture, delivers a 3DMark Steel Nomad DX12 score of 516, placing it in the 1st percentile among all GPUs. The Intel Arc G3, using the Panther Lake chip with Xe3-LPG architecture, currently sits at the 50th percentile with an average benchmark score of zero, meaning it has no recorded performance data to compare directly. The head-to-head benchmark list is empty, and neither part holds any wins in direct comparisons. This analysis relies on the available architectural specifications and the single benchmark result for the AMD part, while the Intel part's performance remains unmeasured.

Where Each One Wins

The AMD Ryzen Z2 Extreme GPU clearly wins in any performance-based comparison because it has actual measured data. Its 3DMark Steel Nomad DX12 score of 516, while modest in absolute terms, represents a concrete result that can be contextualized against nearby rivals. The nearest rival data shows the AMD part sits 3.4% behind the Intel HD Graphics P4000 (which scores 534) and 3.7% behind the AMD Radeon HD 6870 (which scores 536). Against lower-tier rivals, the AMD Ryzen Z2 Extreme GPU leads the AMD Radeon HD 6750M by 6.6% (that rival scores 484) and trails the AMD Radeon HD 6770M by 9.3% (that rival scores 569). These deltas indicate the AMD part occupies a narrow performance band around the 500-540 range in this specific DX12 workload.

The Intel Arc G3 wins in architectural efficiency metrics and feature positioning. Its process node is 3 nm compared to the AMD part's 4 nm, both fabricated by different foundries (TSMC for AMD, Intel for the Arc G3). The Intel part carries 1280 shading units versus 1024 on the AMD side, which contributes to its higher theoretical FP32 throughput of 6.144 TFLOPS against the AMD part's 5.530 TFLOPS. The Arc G3 also doubles its FP16 throughput to 12.29 TFLOPS using a 2:1 ratio, while the AMD part maintains 5.530 TFLOPS FP16 at a 1:1 ratio. This suggests the Intel architecture can handle half-precision workloads more efficiently when software leverages that path.

The AMD Ryzen Z2 Extreme GPU wins on memory configuration and bandwidth. It features 16 GB of dedicated LPDDR5X memory on a 128-bit bus, delivering 128.0 GB/s of bandwidth. The Intel Arc G3 uses system-shared memory with system-dependent bandwidth, meaning its performance scales with the host platform's memory subsystem. The AMD part also has a higher base clock of 800 MHz versus 300 MHz, though the Intel part's boost clock reaches 2400 MHz against the AMD part's 2700 MHz. The AMD GPU's higher pixel rate of 129.6 GPixel/s and texture rate of 172.8 GTexel/s dwarf the Intel part's 48.00 GPixel/s and 96.00 GTexel/s respectively, indicating stronger rasterization throughput per clock.

The Verdict

The data suggests that the AMD Ryzen Z2 Extreme GPU is the only one of the two with measurable performance evidence. Its 3DMark Steel Nomad score of 516, while low in absolute terms, is a real number that can be compared to other GPUs in the database. The Intel Arc G3 has no benchmark scores, no nearest rivals, and an average score of zero, which places it at the 50th percentile only because of the absence of data, not because of demonstrated capability. For any user requiring a GPU with a known performance profile, the AMD part is the only choice supported by recorded measurements.

The Intel Arc G3, however, presents a compelling theoretical case based on its specifications. Its higher shading unit count and FP32 throughput suggest it could outperform the AMD part in compute-heavy workloads once benchmark data becomes available. The 3 nm process node also implies better power efficiency per transistor, though the AMD part's 28 W TDP versus the Intel part's 25 W TDP shows both are designed for low-power mobile or console-class applications. The Intel part's 10 ray tracing cores versus the AMD part's 16 indicate the AMD architecture dedicates more hardware to ray tracing, which could matter for DX12 Ultimate titles.

The verdict from the recorded data is that the AMD Ryzen Z2 Extreme GPU is the verified performer today, while the Intel Arc G3 is an unproven but potentially stronger candidate on paper. The AMD part's nearest rivals all fall within a narrow delta range of -9.3% to +6.6%, demonstrating that its 516 score is consistent with a specific performance tier. The Intel part's lack of any benchmark entries means it cannot be placed in any tier yet. Until the database records results for the Arc G3, the AMD part remains the only option with validated performance.

Head-to-Head Benchmarks

The head-to-head benchmark list contains no entries, and the wins counter shows zero for both parts. This means there is no direct comparative measurement available in the database. The only benchmark score belongs to the AMD Ryzen Z2 Extreme GPU: 516 in 3DMark Steel Nomad DX12. This score places it in the 1st percentile of all GPUs, indicating that most other GPUs in the database outperform it in this specific test. The nearest rivals provide context: the Intel HD Graphics P4000 outscores it by 3.4% (534 versus 516), and the AMD Radeon HD 6870 outscores it by 3.7% (536 versus 516). The AMD Radeon HD 6750M scores 484, which is 6.6% lower than the Ryzen Z2 Extreme's 516, while the AMD Radeon HD 6770M scores 569, which is 9.3% higher.

The absence of any Intel Arc G3 benchmark data means the direct comparison cannot be quantified. The theory from specifications suggests the Intel part's 6.144 TFLOPS FP32 output is 11.1% higher than the AMD part's 5.530 TFLOPS, which could translate to faster compute performance in shader-bound scenes. However, the AMD part's memory bandwidth of 128.0 GB/s from dedicated LPDDR5X memory is a fixed, guaranteed figure, while the Intel part's system-shared memory bandwidth is described as system dependent, making its effective throughput variable and unquantified in the database.

The pixel rate difference is stark: the AMD part achieves 129.6 GPixel/s versus the Intel part's 48.00 GPixel/s, a 2.7x advantage for AMD. The texture rate shows a similar pattern, with the AMD part at 172.8 GTexel/s versus the Intel part's 96.00 GTexel/s, a 1.8x advantage. These metrics suggest that in rasterization-heavy workloads, the AMD Ryzen Z2 Extreme GPU would likely outperform the Intel Arc G3 despite the latter's higher shader count. The AMD part's 16 ray tracing cores versus 10 on the Intel side further indicates stronger RT performance potential, though no RT benchmarks exist in the database.
