Intel Arc G3 Extreme vs NVIDIA GeForce RTX 4080 Max-Q Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is unusual: neither GPU has accumulated individual benchmark scores in the database, and neither has any nearest rival entries populated. The head-to-head benchmark array is empty, with zero wins recorded for either side. This means there is no measured application performance data to walk through, no frame rate comparisons, and no compute workload results that can be cited. What the database does contain is a full set of architectural and specification data for both parts, which allows for a theoretical comparison based on their design parameters.

The Intel Arc G3 Extreme delivers a FP32 compute rating of 7.680 TFLOPS, while the NVIDIA GeForce RTX 4080 Max-Q delivers 20.04 TFLOPS. That is a substantial difference, with NVIDIA holding roughly 2.6 times the raw single-precision throughput. In FP16 work, the gap narrows somewhat: Intel achieves 15.36 TFLOPS using a 2:1 ratio, while NVIDIA also achieves 20.04 TFLOPS but at a 1:1 ratio. NVIDIA still leads, but the Intel part's FP16 mode is comparatively stronger relative to its own FP32 output than NVIDIA's is.

Pixel throughput also favors NVIDIA decisively. The RTX 4080 Max-Q has a pixel rate of 108.0 GPixel/s, against 60.00 GPixel/s for the Arc G3 Extreme. Texture rate shows a similar pattern: 313.2 GTexel/s for NVIDIA versus 120.0 GTexel/s for Intel. These figures indicate that in rasterization-heavy workloads, the NVIDIA part should complete fill-rate-bound tasks roughly twice as fast, based on the theoretical peak rates.

The Intel Arc G3 Extreme uses system shared memory, with bandwidth described as system dependent. The NVIDIA GeForce RTX 4080 Max-Q uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of dedicated memory bandwidth. This is a fundamental difference: the Intel part has no dedicated VRAM and its memory performance depends entirely on the host system's memory configuration, while NVIDIA has a fixed, known bandwidth figure. For workloads that are memory-bandwidth sensitive, the RTX 4080 Max-Q's dedicated 432.0 GB/s is a concrete advantage, whereas the Intel GPU's effective bandwidth cannot be quantified from the database.

Clock speeds tell an interesting story. The Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 4080 Max-Q has a base clock of 795 MHz and a boost clock of 1350 MHz. Intel's boost clock is substantially higher, but NVIDIA's higher base clock and much larger shader count (7424 versus 1536 shading units) more than compensate in the final throughput calculations. The RTX 4080 Max-Q also has 232 texture mapping units and 80 ROPs, against Intel's 48 TMUs and 24 ROPs.

Ray tracing hardware shows NVIDIA with 58 RT cores and 232 tensor cores, while Intel lists 12 RT cores and no tensor core count in the database. NVIDIA's Ada Lovelace architecture clearly carries a much larger complement of dedicated ray tracing and AI acceleration hardware. The database does not provide RT core or tensor core performance metrics, so no direct ray tracing benchmark comparison can be made, but the hardware counts alone indicate a large disparity in parallel processing resources.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are identical. Both are listed as IGP slot width with no power connectors, and both have portable device dependent display outputs. The TDP figures differ, however: Intel is rated at 80 W, while NVIDIA is rated at 60 W. This is notable because the lower TDP NVIDIA part still delivers substantially higher peak compute rates, which suggests significantly better performance per watt based on the recorded data.

The Arc G3 Extreme is manufactured on a 3 nm process by Intel, while the RTX 4080 Max-Q is on a 5 nm process from TSMC. NVIDIA's chip, AD104, contains 35,800 million transistors on a 294 mm² die, with a transistor density of 121.8M per mm². Intel's transistor count and die size are listed as unknown, so no density comparison is possible. The Intel chip is named Panther Lake, while NVIDIA uses AD104.

The Verdict

The data shows two GPUs aimed at different segments despite both being integrated into portable devices. The Intel Arc G3 Extreme is an integrated graphics processor on Intel's Panther Lake chip, using system shared memory with no dedicated VRAM. The NVIDIA GeForce RTX 4080 Max-Q is a discrete-class mobile GPU with 12 GB of dedicated GDDR6 memory. From the specification data alone, the RTX 4080 Max-Q is the stronger part in every quantified compute metric: FP32, FP16, pixel rate, texture rate, memory bandwidth, shader count, TMU count, ROP count, RT core count, and tensor core count.

There is one area where Intel leads: boost clock speed. The Arc G3 Extreme boosts to 2500 MHz versus 1350 MHz for the NVIDIA part. There is also a process node advantage for Intel at 3 nm versus 5 nm, and a TDP difference of 80 W versus 60 W, meaning Intel's part draws more power but delivers less peak throughput. The database shows no benchmark scores for either GPU, so real-world application performance cannot be confirmed. Any purchase decision must be based on the architectural and specification differences alone.

The RTX 4080 Max-Q is the clear choice for workloads that demand raw compute throughput, dedicated memory bandwidth, and substantial ray tracing or tensor core resources. The Arc G3 Extreme is the integrated option for systems where a separate GPU is not an option, offering a 2500 MHz boost clock and 7.680 TFLOPS of FP32 performance without requiring dedicated VRAM. Its system dependent memory bandwidth means its real-world performance will vary with the host platform's memory configuration, which the database cannot quantify.

Architecture Differences

The Intel Arc G3 Extreme uses the Xe3-LPG architecture on the Panther Lake chip, manufactured on Intel's 3 nm process. The NVIDIA GeForce RTX 4080 Max-Q uses the Ada Lovelace architecture on the AD104 chip, manufactured on TSMC's 5 nm process. These are fundamentally different design philosophies: Intel's Xe3-LPG is a low-power graphics architecture intended for integration into a larger processor, while Ada Lovelace is a full discrete GPU architecture with dedicated memory interfaces and large compute arrays.

The compute resources differ sharply. Intel provides 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. NVIDIA provides 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The NVIDIA part has approximately 4.8 times the shading units, 4.8 times the TMUs, 3.3 times the ROPs, and 4.8 times the RT cores. The tensor core count of 232 on the NVIDIA side has no equivalent listed for Intel, which means AI acceleration workloads that rely on tensor cores can only be served by the NVIDIA part according to the database.

Memory architecture is another major differentiator. The Intel part uses system shared memory for both capacity and type, with a system dependent bandwidth figure. The NVIDIA part uses 12 GB of GDDR6 on a 192-bit bus with a fixed 432.0 GB/s bandwidth. This means NVIDIA's memory subsystem is fully self-contained and predictable, while Intel's depends entirely on the host system's memory design. The database lists Intel's memory clock as "System Shared" as well, so there is no fixed memory clock for the Arc G3 Extreme.

FP16 processing also differs in approach. Intel lists FP16 at 15.36 TFLOPS with a 2:1 ratio relative to FP32, meaning it achieves double the FP32 rate by using paired FP32 units. NVIDIA lists FP16 at 20.04 TFLOPS with a 1:1 ratio, meaning its FP16 throughput equals its FP32 throughput. This indicates NVIDIA's shader cores handle FP16 and FP32 at the same rate, while Intel achieves higher FP16 throughput through a different hardware mechanism. For workloads that mix FP16 and FP32, the NVIDIA part maintains consistent throughput, while Intel's FP16 advantage over its own FP32 is notable but still lower in absolute terms.

Power delivery is identical in form: both are IGP slot width with no power connectors, and both have portable device dependent display outputs. The TDP values differ, with Intel at 80 W and NVIDIA at 60 W. This is a significant architectural outcome: the NVIDIA part delivers more compute per watt despite using an older process node, based on the recorded TDP and throughput figures.

Where Each One Wins

The Intel Arc G3 Extreme wins in boost clock speed, with a 2500 MHz boost versus NVIDIA's 1350 MHz. It also uses a smaller process node at 3 nm versus NVIDIA's 5 nm. These are the only quantified categories where Intel holds an advantage in the recorded data. The higher boost clock may help in lightly threaded or latency-sensitive workloads that scale with clock frequency, though the database provides no benchmark scores to confirm this.

The NVIDIA GeForce RTX 4080 Max-Q wins in every other quantified category. It delivers 20.04 TFLOPS of FP32 against Intel's 7.680 TFLOPS, and 20.04 TFLOPS of FP16 against Intel's 15.36 TFLOPS. Its pixel rate of 108.0 GPixel/s is nearly double Intel's 60.00 GPixel/s, and its texture rate of 313.2 GTexel/s is more than 2.5 times Intel's 120.0 GTexel/s. Memory bandwidth is fixed at 432.0 GB/s with 12 GB of GDDR6, while Intel's memory performance is system dependent and unquantified. The NVIDIA part also has far more shading units, TMUs, ROPs, RT cores, and tensor cores, plus a lower TDP of 60 W versus 80 W.

For use cases involving heavy rasterization, ray tracing, AI workloads with tensor cores, or memory-bandwidth-intensive tasks, the data clearly favors the NVIDIA GeForce RTX 4080 Max-Q. For systems that require an integrated GPU with a very high boost clock and a 3 nm process, the Intel Arc G3 Extreme is the only option of the two that fits that role. The database shows no benchmark wins for either part, so these conclusions rest entirely on the architectural and specification data recorded.
