Intel Arc G3 vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The Intel Arc G3, an integrated graphics processor within the Panther Lake chip, currently has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and it holds a percentile rank of 50 among all GPUs. In contrast, the NVIDIA RTX 4000 Ada Generation has extensive recorded results, with an average benchmark score of 135,218 and a percentile rank of 95.

The RTX 4000 Ada Generation delivers 146,593 in the Geekbench OpenCL test and 123,842 in the Geekbench Vulkan test. These are substantial scores that place it firmly in the upper tier of the database. The Intel Arc G3, lacking any recorded scores, cannot be measured against these figures. This absence of data is itself a critical finding: the database shows no head-to-head benchmarks between these two products, and the wins counter for each is zero.

The RTX 4000 Ada Generation's nearest rivals in the database provide context for its performance tier. The NVIDIA A10M scores 135,230, which is effectively identical to the RTX 4000's 135,218, showing a delta of 0%. The AMD Radeon PRO W6800 trails by 0.1% with a score of 135,396, while the AMD Radeon Pro W6800X Duo scores 135,774, a 0.4% gap. The AMD Radeon PRO V620 leads this group with 136,472, sitting 0.9% above the RTX 4000. These figures show that the RTX 4000 Ada Generation competes in a tightly clustered performance band where the largest measured difference among its nearest rivals is less than 1%.

The theoretical compute figures reinforce the gap between the two cards. The RTX 4000 Ada Generation delivers 26.73 TFLOPS of FP32 performance, while the Arc G3 provides 6.144 TFLOPS. That is a 4.35 times advantage for the NVIDIA part in raw single-precision throughput. The pixel rate tells a similar story: the RTX 4000 reaches 139.2 GPixel/s versus 48.00 GPixel/s for the Arc G3. The texture rate gap is even wider, with the RTX 4000 at 417.6 GTexel/s compared to 96.00 GTexel/s for the Intel part. In FP16 compute, the RTX 4000 achieves 26.73 TFLOPS at a 1:1 ratio, while the Arc G3 reaches 12.29 TFLOPS using a 2:1 ratio, meaning the NVIDIA card holds a 2.17 times advantage even when the Intel part's rate is doubled.

Architecture Differences

The two products represent fundamentally different design philosophies. The Intel Arc G3 is an integrated graphics processor built on Intel's 3 nm process node, fabricated in-house by Intel. It uses the Xe3-LPG architecture and belongs to the Arc Graphics-M generation for Panther Lake. The chip integrates the GPU directly into the processor package, with its memory being system shared. The base clock is 300 MHz with a boost clock of 2400 MHz, and memory bandwidth is marked as system dependent.

The NVIDIA RTX 4000 Ada Generation is a discrete workstation card built on TSMC's 5 nm process. It uses the AD104 chip with the Ada Lovelace architecture. The transistor count is 35,800 million on a die size of 294 mm², yielding a transistor density of 121.8 million transistors per square millimeter. The Intel part's transistor count and die size are listed as unknown in the database. The RTX 4000 has a base clock of 1500 MHz and a boost clock of 2175 MHz, with dedicated GDDR6 memory running at 2250 MHz with 18 Gbps effective speed.

The compute resources differ sharply. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 raster operations units, and 10 ray tracing cores. The RTX 4000 has 6,144 shading units, 192 TMUs, 64 ROPs, and 48 RT cores. The NVIDIA card also includes 192 tensor cores, while the Intel part lists no tensor core count. These structural differences explain the compute throughput gaps: the RTX 4000 has 4.8 times the shading units, 4.8 times the TMUs, 3.2 times the ROPs, and 4.8 times the RT cores.

The memory subsystem is a major architectural divider. The Arc G3 uses system shared memory with no dedicated VRAM, with its bus width and bandwidth marked as system dependent. The RTX 4000 has 20 GB of GDDR6 on a 160-bit bus, delivering 360.0 GB/s of bandwidth. The power envelopes reflect this: the Arc G3 has a TDP of 25 W and uses no power connectors, while the RTX 4000 has a 130 W TDP and requires a single 16-pin power connector, with a suggested power supply of 300 W.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical. The form factors differ completely: the Arc G3 is an integrated graphics processor with an IGP bus interface and no slot width, while the RTX 4000 is a single-slot card measuring 245 mm or 9.6 inches in length and 112 mm or 4.4 inches in height, using a PCIe 4.0 x16 interface. Display outputs also differ: the Arc G3's outputs are portable device dependent, while the RTX 4000 provides 4x DisplayPort 1.4a.

The Verdict

The data shows two products serving entirely different roles. The Intel Arc G3 is an integrated GPU with a 25 W power draw, designed for portable devices where the display output is device dependent. Its performance metrics, while unmeasured in the database, are theoretically bounded by its 6.144 TFLOPS FP32 ceiling and system shared memory. The NVIDIA RTX 4000 Ada Generation is a discrete workstation card with dedicated 20 GB GDDR6 memory, 26.73 TFLOPS FP32 performance, and a 95th percentile rank among all GPUs in the database.

For workloads requiring sustained compute throughput, the RTX 4000 Ada Generation is the clear choice based on the recorded specifications. Its nearest rivals in the database, all within 0.9% of its average benchmark score, are themselves high-end workstation parts. The RTX 4000's 146,593 OpenCL score and 123,842 Vulkan score place it in the top 5% of all GPUs tracked in the database. The Arc G3, sitting at the 50th percentile with no recorded benchmarks, cannot be positioned relative to these results.

For power-constrained or space-constrained systems, the Arc G3 has advantages that are purely structural. At 25 W with no power connectors and an IGP bus interface, it requires no additional cooling or power delivery beyond what the host processor provides. The RTX 4000 needs a 16-pin connector and a 300 W suggested power supply. The Arc G3's compact integration also eliminates the need for a 245 mm long card. However, these are form factor benefits, not performance benefits. The database records no scenario where the Arc G3 outperforms the RTX 4000, and the theoretical compute figures show the NVIDIA part ahead in every measured category.

The release dates place the Arc G3 in 2026, while the RTX 4000 launched in 2023. The RTX 4000's predecessor is Workstation Ampere, and its successor is Blackwell PRO W. The Arc G3 has no listed predecessor or successor. This suggests the RTX 4000 is a mature product in an established workstation lineup, while the Arc G3 represents a newer integrated solution without a documented product history.
