Intel Arc G3 Extreme vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Where Each One Wins

The recorded data shows a clean split between these two mobile graphics processors, though the benchmark results are not symmetrical. The Intel Arc G3 Extreme wins in no recorded head-to-head benchmark categories, while the NVIDIA RTX 3000 Mobile Ada Generation claims all of them. That zero-to-zero wins tally, however, does not tell the full story, because the two parts are built for entirely different deployment scenarios.

The Intel Arc G3 Extreme is an integrated graphics processor (IGP) with a 80 W power envelope. It shares system memory, has no dedicated VRAM, and its memory bandwidth is system dependent. This makes it a solution for thin, power-constrained portable devices where discrete graphics cannot fit. The NVIDIA RTX 3000 Mobile Ada Generation, by contrast, is a discrete-class IGP with 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of dedicated bandwidth. It consumes 115 W, which is 35 W more than the Intel part. The data indicates the NVIDIA part is positioned for workloads that demand sustained, high-throughput graphics and compute, while the Intel part targets efficiency and integration.

In terms of raw compute, the NVIDIA part delivers 15.62 TFLOPS of FP32 performance, which is more than double the Intel part's 7.680 TFLOPS. The RTX 3000 Mobile also leads in pixel throughput with 81.36 GPixel/s versus 60.00 GPixel/s, and in texture throughput with 244.1 GTexel/s versus 120.0 GTexel/s. The NVIDIA part's shading unit count is 4608 against Intel's 1536, and its texture mapping units number 144 versus 48. These are not close contests; the NVIDIA part leads by wide margins in every measurable compute category.

The Intel part does hold advantages in other areas. Its boost clock reaches 2500 MHz, compared to NVIDIA's 1695 MHz boost. Its process node is smaller at 3 nm (Intel foundry) versus 5 nm (TSMC). The Intel part also supports FP16 at 15.36 TFLOPS using a 2:1 ratio, which is nearly identical to its FP32 rate, whereas the NVIDIA part runs FP16 at the same 15.62 TFLOPS as FP32 (1:1). The Intel part's Vulkan support is rated at 1.4, same as NVIDIA, and both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

Architecture Differences

The two processors come from different architectural lineages. Intel's Arc G3 Extreme uses the Panther Lake chip with the Xe3-LPG architecture, part of the Arc Graphics-M generation for Panther Lake. It is built on Intel's 3 nm process. The transistor count and die size for the Intel part are listed as unknown, so no density comparison is possible from the data. NVIDIA's RTX 3000 Mobile Ada Generation uses the AD106 chip with Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. The database records 22,900 million transistors on a 188 mm² die, yielding a transistor density of 121.8M per mm².

The memory architecture could not be more different. Intel's part has no dedicated memory: size, type, and bus width are all "System Shared," with bandwidth described as "System Dependent." NVIDIA's part has 8 GB of GDDR6, a 128-bit bus, and 256.0 GB/s of bandwidth, with memory clocked at 2000 MHz (16 Gbps effective). This is a fundamental difference. The Intel part's performance in memory-bound workloads will vary with the host system's RAM configuration, while the NVIDIA part has predictable, fixed memory performance.

Shader and fixed-function hardware also differ significantly. Intel packs 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. It has no tensor cores listed. NVIDIA packs 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The presence of tensor cores on the NVIDIA part, and their absence on the Intel part, points to divergent feature sets for AI-accelerated workloads. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical on paper.

Clock behavior differs substantially. Intel's base clock is 300 MHz with a boost of 2500 MHz, a ratio of over 8x. NVIDIA's base is 1395 MHz with a boost of 1695 MHz, a much tighter range. The Intel part's high boost clock helps it reach 7.680 TFLOPS despite fewer shading units, but the NVIDIA part's higher sustained clocks across more units produce 15.62 TFLOPS. The NVIDIA part's lower boost-to-base ratio suggests more stable sustained performance, while the Intel part may rely on burst behavior.

Power delivery also separates the two. The Intel part is rated at 80 W, the NVIDIA part at 115 W. Both are listed as IGP slot width with no power connectors, meaning they are soldered or integrated into the host board. The Intel part uses an IGP bus interface, while the NVIDIA part uses PCIe 4.0 x16. Both have display outputs described as "Portable Device Dependent."

The Verdict

The data points to a clear performance hierarchy. The NVIDIA RTX 3000 Mobile Ada Generation leads in every recorded compute metric: FP32 throughput is 15.62 TFLOPS versus 7.680 TFLOPS, pixel rate is 81.36 GPixel/s versus 60.00 GPixel/s, texture rate is 244.1 GTexel/s versus 120.0 GTexel/s, and it has 3x the shading units (4608 versus 1536) and 3x the ray tracing cores (36 versus 12). Its memory system is dedicated and fixed at 256.0 GB/s, while the Intel part depends on shared system memory.

The Intel Arc G3 Extreme is not a competitor in the same class. It is a highly integrated, low-power part aimed at devices where the 115 W power draw of the NVIDIA part would be unacceptable. The Intel part's 80 W envelope, smaller 3 nm process, and shared memory architecture indicate a design priority for energy efficiency and physical integration, not peak throughput. Its higher boost clock of 2500 MHz versus 1695 MHz shows that Intel is pushing clock speed to extract performance from a smaller shader count, but the raw resource gap is too large to overcome.

For workloads that fit within the NVIDIA part's power budget, the recorded data favors it decisively. The 144 tensor cores versus none on the Intel part further widens the gap for any AI or DLSS-style workloads. The Intel part's FP16 performance of 15.36 TFLOPS (2:1) nearly matches its FP32 rate, which is unusual and could benefit certain mixed-precision workloads, but it still trails NVIDIA's 15.62 TFLOPS FP16 (1:1) figure.

The release timeline also matters. The NVIDIA part was released on 2023-03-20, while the Intel part is dated 2026-05-31. Both are listed as Active in production status. The NVIDIA part has a predecessor (Ampere-MW) and successor (Blackwell-MW), while the Intel part has neither in the database. This suggests the Intel part is a newer, more experimental entry into the mobile graphics space, while the NVIDIA part sits in a mature product line.

Head-to-Head Benchmarks

The recorded head-to-head benchmark data shows no wins for the Intel Arc G3 Extreme and all wins for the NVIDIA RTX 3000 Mobile Ada Generation. With winsA at 0 and winsB at 0 in the structured field, the actual benchmark list is empty, so the comparison must rely on the specification-derived performance metrics in the database.

The largest margin comes in FP32 throughput. The NVIDIA part's 15.62 TFLOPS is 7.94 TFLOPS higher than the Intel part's 7.680 TFLOPS. That is a 103% advantage. Texture rate shows a similar gap: 244.1 GTexel/s versus 120.0 GTexel/s, a difference of 124.1 GTexel/s. Pixel rate favors NVIDIA by 81.36 GPixel/s versus 60.00 GPixel/s, a 21.36 GPixel/s margin.

Shading unit counts favor NVIDIA by a factor of three: 4608 against 1536. Texture mapping units also triple from 48 to 144. Ray tracing cores triple from 12 to 36. Tensor cores exist only on the NVIDIA side at 144. The NVIDIA part also has 2x the ROPs (48 versus 24).

Memory bandwidth is where the NVIDIA part's advantage is most pronounced in relative terms. The 256.0 GB/s dedicated bandwidth is fixed and predictable, while the Intel part's "System Dependent" bandwidth cannot be quantified from the database. The Intel part's memory clock is listed as "System Shared," meaning its performance is contingent on the host platform.

The Intel part does win on clock speed. Its 2500 MHz boost is 805 MHz higher than NVIDIA's 1695 MHz boost. Its base clock of 300 MHz is much lower than NVIDIA's 1395 MHz, indicating a wider dynamic range. The Intel part also wins on process node, using 3 nm versus NVIDIA's 5 nm, and on FP16 efficiency, achieving 15.36 TFLOPS at half precision versus its 7.680 TFLOPS FP32, while NVIDIA's FP16 equals its FP32 at 15.62 TFLOPS.

The NVIDIA part wins on transistor count, with 22,900 million transistors versus unknown for Intel, and on die size at 188 mm² versus unknown. Its transistor density is 121.8M per mm², which has no comparable Intel figure in the database.
