Intel Arc G3 Extreme vs Intel Arc Graphics 48EU Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark comparisons between the Intel Arc G3 Extreme and the Intel Arc Graphics 48EU Mobile. The head-to-head benchmark array is empty, and neither part registers a win in competitive testing. This absence of measured data means the performance relationship must be derived entirely from the architectural and specification differences recorded in the database.

The compute throughput gap is stark. The Arc G3 Extreme delivers 7.680 TFLOPS of FP32 performance, while the Arc Graphics 48EU Mobile provides 1,382.4 GFLOPS. That places the G3 Extreme at roughly 5.5 times the raw shader output of the mobile part. In FP16 workloads, the G3 Extreme reaches 15.36 TFLOPS (2:1) against 2.765 TFLOPS (2:1) for the 48EU Mobile, a ratio that holds at approximately 5.5x as well. These figures derive from the shading unit counts: 1536 units on the G3 Extreme versus 384 on the 48EU Mobile, exactly four times the execution resources, combined with a boost clock of 2500 MHz versus 1800 MHz.

Texture and pixel throughput follow the same pattern. The G3 Extreme sustains 120.0 GTexel/s and 60.00 GPixel/s. The 48EU Mobile manages 43.20 GTexel/s and 14.40 GPixel/s. The pixel rate difference is particularly pronounced, a 4.17x advantage for the G3 Extreme, which reflects both the higher ROP count (24 versus 8) and the faster clock. Texture rate shows a 2.78x gap, driven by 48 TMUs versus 24 TMUs, though the clock difference narrows that ratio relative to the raw unit count.

The database records neither part's average benchmark score above zero, and both sit at the 50th percentile among all GPUs. With no nearest rivals listed for either product, there is no external reference point to contextualize these raw specifications. The conclusion from the available data is straightforward: the G3 Extreme outperforms the 48EU Mobile across every recorded throughput metric, with the largest margins in pixel fill and the smallest, though still substantial, in texture fill.

Architecture Differences

The two GPUs represent different generations of Intel's integrated graphics design. The Arc G3 Extreme is built on the Xe3-LPG architecture, which is a newer design than the Xe-LPG architecture found in the Arc Graphics 48EU Mobile. The process node difference is significant: the G3 Extreme uses a 3 nm process, while the 48EU Mobile uses a 10 nm process. This node advantage contributes to the G3 Extreme's ability to pack 1536 shading units into an 80 W envelope, compared to 384 shading units in a 28 W envelope for the 48EU Mobile.

The G3 Extreme's chip is Panther Lake, while the 48EU Mobile uses Meteor Lake. Both are active production parts, but the G3 Extreme has a release date of May 2026, over two years after the 48EU Mobile's December 2023 release. The 48EU Mobile lists a predecessor, HD Graphics-M, while the G3 Extreme has no recorded predecessor or successor.

DirectX support separates the two architectures clearly. The G3 Extreme supports DirectX 12 Ultimate (12_2), which includes the full feature set for modern rendering techniques such as mesh shaders and variable rate shading. The 48EU Mobile is limited to DirectX 12 (12_1), a more restricted feature level. OpenGL support is identical at 4.6, and both support Vulkan 1.4.

Ray tracing is a major architectural divergence. The G3 Extreme includes 12 dedicated ray tracing cores, enabling hardware-accelerated ray tracing workloads. The 48EU Mobile records no ray tracing cores at all, meaning any ray tracing on that part would be software-based, which is not a practical option for real-time rendering. This is the clearest functional difference between the two architectures beyond raw throughput.

The memory subsystem is architecturally identical in approach: both use system-shared memory with a system-shared bus width and system-dependent bandwidth. Neither GPU has dedicated video memory, which is consistent with their integrated nature. The G3 Extreme's faster internal execution does not translate to a memory bandwidth advantage, since bandwidth is determined by the host system's memory configuration in both cases.

Specification Differences

The recorded specifications show a consistent pattern of the G3 Extreme exceeding the 48EU Mobile across execution resources. Shading units: 1536 versus 384. Texture mapping units: 48 versus 24. Render output units: 24 versus 8. Ray tracing cores: 12 versus none. Each of these differences compounds the performance gap in specific workload types.

Clock speeds differ in both base and boost. The base clock is identical at 300 MHz for both parts, but the boost clock favors the G3 Extreme at 2500 MHz versus 1800 MHz. This 700 MHz boost advantage means the G3 Extreme not only has more units, it runs those units faster under load.

Process node and TDP differentiate the parts physically. The G3 Extreme uses a 3 nm process with an 80 W TDP. The 48EU Mobile uses a 10 nm process with a 28 W TDP. The power envelope is nearly three times larger on the G3 Extreme, which is a direct consequence of the higher execution resource count and clock speed.

The bus interface differs: the G3 Extreme uses IGP, while the 48EU Mobile uses Ring Bus. Both are integrated solutions with no power connectors. The G3 Extreme records a slot width of IGP, while the 48EU Mobile does not record a slot width, though its mobile nature implies an integrated design.

API support diverges at the DirectX level. The G3 Extreme supports 12 Ultimate (12_2), and the 48EU Mobile supports 12 (12_1). OpenGL and Vulkan versions match at 4.6 and 1.4 respectively. The release dates place the G3 Extreme at May 2026 and the 48EU Mobile at December 2023, with the 48EU Mobile having a recorded predecessor of HD Graphics-M.

Memory specifications are identical in form: both are system shared with system shared type, bus width, and system dependent bandwidth. No memory size is dedicated to either GPU. Display outputs are portable device dependent for both, indicating their use in laptops and similar portable devices.

The Verdict

The data shows a clear performance hierarchy. The Intel Arc G3 Extreme outperforms the Intel Arc Graphics 48EU Mobile in every recorded compute metric, with advantages ranging from 2.78x in texture rate to 5.5x in FP32 throughput. The pixel rate advantage of 4.17x and the presence of 12 ray tracing cores further separate the two parts.

The 48EU Mobile is not without merit. Its 28 W TDP is substantially lower than the G3 Extreme's 80 W TDP, which matters for battery-powered devices where thermal and power budgets are constrained. The 48EU Mobile's DirectX 12 (12_1) support covers most games and applications from its era, and its 300 MHz base clock matches the G3 Extreme. For light gaming, media playback, and general productivity, the 48EU Mobile provides functional integrated graphics.

The G3 Extreme targets a different class of device. Its 80 W TDP suggests it is intended for high-performance laptops or portable workstations where the extra power draw is acceptable in exchange for 7.680 TFLOPS of FP32 compute, 120.0 GTexel/s texture throughput, and 60.00 GPixel/s pixel fill. The 2:1 FP16 ratio of 15.36 TFLOPS indicates potential for machine learning and AI inference workloads that benefit from reduced precision arithmetic.

The database records both parts at the 50th percentile among all GPUs, but this percentile is based on no actual benchmark scores, as the average benchmark score is zero for both. Without measured performance data, the specification comparison is the only available evidence. That evidence points to the G3 Extreme as the stronger part by a wide margin.

Where Each One Wins

The Intel Arc G3 Extreme wins in raw compute throughput. Its 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1) figures make it suitable for workloads that demand substantial shader processing, such as 3D rendering, video encoding, and computational tasks in scientific or engineering applications. The 12 ray tracing cores give it a decisive edge in ray-traced gaming and rendering workloads, where the 48EU Mobile has no hardware acceleration.

The G3 Extreme also wins in texture-heavy scenarios. Its 120.0 GTexel/s texture rate handles high-resolution texture sampling more effectively than the 48EU Mobile's 43.20 GTexel/s. The pixel rate advantage of 60.00 GPixel/s versus 14.40 GPixel/s means the G3 Extreme can drive higher display resolutions and refresh rates without becoming the bottleneck.

The Intel Arc Graphics 48EU Mobile wins in power efficiency. Its 28 W TDP is less than half the G3 Extreme's 80 W TDP, making it the appropriate choice for ultraportable laptops and fanless designs where heat dissipation and battery life take priority over performance. For everyday tasks like web browsing, office applications, and streaming video, the 48EU Mobile's 384 shading units and 1800 MHz boost clock provide adequate performance at a fraction of the power draw.

The 48EU Mobile also holds a timing advantage in the database. Released in December 2023, it has been on the market for over two years by the G3 Extreme's May 2026 release date. This means the 48EU Mobile has more recorded production history and ecosystem maturity, though the database does not include specific software support data.

The G3 Extreme's Xe3-LPG architecture with DirectX 12 Ultimate (12_2) support makes it the winner for modern gaming titles that require the latest DirectX feature levels. The 48EU Mobile's DirectX 12 (12_1) support excludes features that some newer games may mandate. The 48EU Mobile remains viable for older titles and less demanding applications, but the G3 Extreme is the only one of the two that can claim full support for the current DirectX feature set.
