AMD Radeon RX 7800 XT vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Radeon RX 7800 XT and the Intel Arc G3 Extreme. The database contains no overlapping test scores for these two products, which means a direct numerical comparison across identical workloads cannot be established from the available measurements.

However, the AMD Radeon RX 7800 XT has a comprehensive set of benchmark scores, while the Intel Arc G3 Extreme has none recorded. The RX 7800 XT delivers 4157 points in 3DMark Steel Nomad DX12, 18290 in Geekbench OpenCL, 54228 in Geekbench Vulkan, and 24176 in Passmark G3D. Its Passmark sub-scores include 121 in DirectX 10, 249 in DirectX 11, 93 in DirectX 12, 304 in DirectX 9, 1177 in G2D, and 13473 in GPU Compute.

The average benchmark score for the RX 7800 XT is 11627, placing it in the 51st percentile among all GPUs. Its nearest rivals in the database are the NVIDIA GeForce GTX 1660 (average score 11680, delta -0.5%), AMD Radeon Pro 5500M (11528, delta +0.9%), NVIDIA Tesla K20c (11479, delta +1.3%), and AMD Radeon RX 6500 XT (11842, delta -1.8%). The RX 7800 XT sits within 1.8% of these cards, indicating a tight cluster of performance around the 11.5k to 11.8k average score range.

Because the Intel Arc G3 Extreme has zero recorded benchmarks and an average score of 0, it cannot be ranked against the RX 7800 XT in any test. The database assigns it the 50th percentile based on its specifications alone, but without actual scores, any head-to-head comparison remains speculative. The RX 7800 XT, by contrast, has measurable results across nine distinct tests, giving it a clear empirical footprint.

Architecture Differences

The AMD Radeon RX 7800 XT uses the Navi 32 chip on RDNA 3.0 architecture, with the codename "Wheat Nas" and belongs to the Navi III (RX 7000) generation. It is fabricated on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter.

The Intel Arc G3 Extreme uses the Panther Lake chip on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel, but its transistor count, die size, and transistor density are listed as unknown in the database.

The RX 7800 XT features 3840 shading units, 240 texture mapping units, 96 render output units, and 60 ray tracing cores. The Arc G3 Extreme has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. This represents a 2.5x difference in shading units, 5x in TMUs, and 4x in ROPs in favor of the AMD card.

Clock speeds differ substantially. The RX 7800 XT has a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. Its memory runs at 2438 MHz with 19.5 Gbps effective. The Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz, with system-shared memory. The boost clocks are similar, but the base clock is over 4x lower on the Intel part.

Memory architecture is fundamentally different. The RX 7800 XT uses 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The Arc G3 Extreme uses system-shared memory, with type, bus width, and bandwidth all listed as system dependent. This means the Intel GPU relies on the host system's memory bandwidth, which varies by platform.

Compute throughput shows a large gap. The RX 7800 XT delivers 37.32 TFLOPS FP32 and 37.32 TFLOPS FP16 (1:1 ratio). The Arc G3 Extreme delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1 ratio). The AMD card has nearly 5x the FP32 throughput, while its FP16 output is about 2.4x higher in absolute terms.

Pixel and texture rates follow the same pattern. The RX 7800 XT achieves 233.3 GPixel/s and 583.2 GTexel/s, while the Arc G3 Extreme manages 60.00 GPixel/s and 120.0 GTexel/s. The AMD card is roughly 3.9x faster in pixel fill and 4.9x faster in texture fill.

Power and physical design differ completely. The RX 7800 XT has a TDP of 263 W, requires dual-slot cooling, uses 2x 8-pin power connectors, and needs a 600 W suggested PSU. It is 267 mm long, 111 mm tall, and 50 mm wide. The Arc G3 Extreme has an 80 W TDP, is an integrated graphics processor (IGP) with no slot width, no power connectors, and no listed PSU requirement. It has no physical dimensions recorded.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7800 XT uses PCIe 4.0 x16 and has 1x HDMI 2.1a plus 3x DisplayPort 2.1 outputs. The Arc G3 Extreme uses an IGP bus interface with portable device dependent display outputs. API compatibility is identical, but the physical and platform integration differs entirely.

Where Each One Wins

The RX 7800 XT wins in every measurable benchmark category because it has recorded scores and the Arc G3 Extreme does not. The data shows the RX 7800 XT delivering 4157 in 3DMark Steel Nomad DX12, a modern DirectX 12 workload. Its Vulkan score of 54228 in Geekbench indicates strong low-level API performance for a discrete card in this class.

For compute workloads, the RX 7800 XT posts 18290 in Geekbench OpenCL and 13473 in Passmark GPU Compute. These numbers reflect its 37.32 TFLOPS FP32 capability, which is about 4.9x higher than the Arc G3 Extreme's 7.680 TFLOPS. The RX 7800 XT's FP16 output at 37.32 TFLOPS is also higher than the Arc's 15.36 TFLOPS, though the Intel part's 2:1 FP16 ratio shows it can double its rate for half-precision work.

The RX 7800 XT's 624.1 GB/s memory bandwidth is a decisive advantage for texture-heavy and high-resolution workloads. The Arc G3 Extreme's system-shared memory bandwidth is system dependent, meaning it cannot match a dedicated 256-bit GDDR6 interface in sustained throughput.

The Arc G3 Extreme wins in power efficiency and integration. Its 80 W TDP is 183 W lower than the RX 7800 XT's 263 W. It requires no power connectors, no dedicated slot, and no PSU upgrade. For compact or low-power systems, the Arc G3 Extreme fits where the RX 7800 XT cannot physically go. Its 2500 MHz boost clock is slightly higher than the RX 7800 XT's 2430 MHz, but the AMD card's game clock of 2124 MHz provides a realistic sustained frequency.

In rasterization throughput, the RX 7800 XT dominates with 233.3 GPixel/s versus 60.00 GPixel/s. Texture work shows 583.2 GTexel/s versus 120.0 GTexel/s. These are 3.9x and 4.9x advantages respectively, which translates directly to higher frame rates in most gaming scenarios.

The Verdict

The data supports a clear separation: the RX 7800 XT is a high-performance discrete GPU for gaming and compute, while the Arc G3 Extreme is an integrated solution for low-power systems. The RX 7800 XT's 37.32 TFLOPS FP32, 16 GB GDDR6, and 624.1 GB/s bandwidth place it in the 51st percentile of all GPUs, with an average score of 11627. Its nearest rival, the GTX 1660, is within 0.5%, meaning the RX 7800 XT trades blows with that card in average performance across the database.

The Arc G3 Extreme, with no recorded benchmarks, cannot be positioned on a performance curve. Its 50th percentile ranking appears to be a default assignment rather than a measured result. The 7.680 TFLOPS FP32 and 60.00 GPixel/s pixel rate suggest it is roughly one-fifth the compute capability of the RX 7800 XT, but without actual test scores, this remains a specification-based estimate.

For users who need a discrete GPU with dedicated memory and high throughput, the RX 7800 XT is the only option with measured data. For users who need a low-power integrated GPU in a portable device, the Arc G3 Extreme has no recorded performance to validate its capabilities. The RX 7800 XT is an active product with a launch MSRP of 499 USD. The Arc G3 Extreme is also active, with no launch MSRP recorded.

The verdict from the database is straightforward: the RX 7800 XT has empirical performance data across nine benchmarks and a 51st percentile ranking. The Arc G3 Extreme has none. Any purchasing decision should account for the fact that the Intel part's performance is entirely unverified in this dataset.
