Intel Arc G3 vs NVIDIA L4 Comparison

Intel Arc G3 and NVIDIA L4 occupy very different corners of the hardware landscape. The G3 is an integrated graphics processor built for mobile Panther Lake chips, while the L4 is a dedicated server accelerator. Direct head-to-head benchmark data between the two is absent from the database, so the comparison relies on their recorded specifications, each product’s own benchmark scores, and their positions relative to other GPUs in the database.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries pairing the Intel Arc G3 against the NVIDIA L4. Instead, the comparison must be assembled from each product’s own measured results plus their placement among all tracked GPUs.

The NVIDIA L4 has two recorded benchmark scores. In the Geekbench OpenCL test, it scores 140838 points. In the Geekbench Vulkan test, it scores 121306 points. Its average benchmark score across the database is 131072. That average places the L4 at the 95th percentile of all GPUs in the database, meaning it outperforms roughly 95 percent of tracked graphics hardware. Its nearest rivals in the database include the NVIDIA GeForce RTX 3090 Ti with an average score of 131938, a delta of -0.7 percent relative to the L4. The NVIDIA RTX 4000 Ada Generation averages 135218, which is 3.1 percent above the L4. The NVIDIA A10M also sits 3.1 percent above the L4 at 135230. The AMD Radeon PRO W6800 averages 135396, again 3.2 percent ahead.

The Intel Arc G3 has no benchmark scores recorded in the database. Its average benchmark score is listed as 0, and its percentile versus all GPUs is 50. That percentile indicates the G3 sits at the median of the database distribution, but with zero recorded test results, the percentile likely reflects its position in the product list rather than measured performance data. The G3 also has no nearest rivals listed, which prevents any delta comparisons against adjacent hardware.

What the recorded data does show is that the L4’s raw compute figures are far higher than the G3’s. The L4 delivers 30.29 TFLOPS of FP32 performance, while the G3 delivers 6.144 TFLOPS. The L4 achieves 30.29 TFLOPS of FP16 performance at a 1:1 ratio, while the G3 reaches 12.29 TFLOPS at a 2:1 ratio. The L4’s pixel rate is 163.2 GPixel/s versus the G3’s 48.00 GPixel/s. The L4’s texture rate is 489.6 GTexel/s versus the G3’s 96.00 GTexel/s.

Where Each One Wins

The NVIDIA L4 wins clearly in any scenario that demands raw compute throughput. Its FP32 output of 30.29 TFLOPS is roughly five times the G3’s 6.144 TFLOPS. Its FP16 output of 30.29 TFLOPS at a 1:1 ratio means it does not halve its throughput when working with reduced precision, whereas the G3’s 12.29 TFLOPS figure at a 2:1 ratio implies a more modest FP16 capability. The L4 also has 7424 shading units, 240 texture mapping units, 80 render output units, 60 ray tracing cores, and 240 tensor cores. The G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores, with no tensor cores listed.

The L4’s memory subsystem is also decisively stronger. It has 24 GB of GDDR6 memory on a 192-bit bus, with 300.1 GB/s of bandwidth. The G3 uses system-shared memory with a system-dependent bandwidth figure, so its memory performance cannot be quantified from the database. For workloads that fit within large memory capacities, such as server-side inference or rendering tasks, the L4’s dedicated 24 GB pool is a clear advantage.

The Intel Arc G3 wins in the categories of integration and power draw. Its TDP is 25 W, and it uses no power connectors. The L4 has a 72 W TDP and also uses no power connectors, but it requires a suggested PSU of 250 W. The G3 is an IGP with no separate slot width, while the L4 is a single-slot card. The G3 draws power from the host system through the integrated graphics path, whereas the L4 needs a PCIe 4.0 x16 slot and a 250 W power supply recommendation.

Architecture Differences

The two chips come from different manufacturers, foundries, and process nodes. Intel builds the Arc G3 on a 3 nm process at its own foundry, using the Panther Lake chip and the Xe3-LPG architecture. NVIDIA builds the L4 on a 5 nm process at TSMC, using the AD104 chip and the Ada Lovelace architecture.

The G3 belongs to the Arc Graphics-M (Panther Lake) generation, while the L4 belongs to the Server Ada (Lxx) generation. The L4’s predecessor is listed as Server Ampere and its successor as Server Hopper, giving it a clear lineage within NVIDIA’s server product stack. The G3 has no predecessor or successor listed in the database.

Transistor and die data differ sharply. The L4 has 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8M per mm². The G3’s transistor count and die size are listed as unknown, so no density figure can be computed.

Clock behavior also differs. The G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The L4 has a base clock of 795 MHz and a boost clock of 2040 MHz. The G3 starts much lower but boosts higher, while the L4 runs a narrower clock range. The L4’s memory clock is 1563 MHz with 12.5 Gbps effective data rate. The G3’s memory clock is listed as system shared.

API support is identical on paper. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The L4 has no display outputs, which is typical for a server accelerator. The G3’s display outputs are listed as portable device dependent, reflecting its integrated role in mobile systems.

The Verdict

The recorded data points to a clear split between the two products. The NVIDIA L4 is a high-throughput server accelerator with measured benchmark results at the 95th percentile of all GPUs. Its average score of 131072 places it near the NVIDIA GeForce RTX 3090 Ti, which trails by 0.7 percent, and within 3.2 percent of several other high-end workstation cards. Its 24 GB GDDR6 memory, 300.1 GB/s bandwidth, 30.29 TFLOPS FP32, and 240 tensor cores position it for compute-heavy server workloads.

The Intel Arc G3 is an integrated GPU with no recorded benchmark scores, no tensor cores, system-shared memory, and 6.144 TFLOPS FP32. Its 25 W TDP and IGP form factor make it a low-power component for portable devices. The data does not support treating the two as competitors. The L4 dominates every compute metric in the database, while the G3 offers integration and low power draw. A system builder targeting server inference or rendering would select the L4 based on its measured scores and memory capacity. A mobile platform designer would select the G3 for its integrated nature and 25 W envelope. The benchmark database confirms the L4’s position in the top tier of GPUs, while the G3’s lack of recorded results leaves its real-world standing unmeasured.
