Intel Arc A770 vs NVIDIA RTX A4500 Mobile Comparison

The NVIDIA RTX A4500 Mobile and Intel Arc A770 are two very different GPUs that land in similar performance territory in one benchmark, yet diverge sharply in architecture, power requirements, and intended use. The data shows a clear split: the Intel Arc A770 wins both head-to-head benchmark tests, but the NVIDIA RTX A4500 Mobile holds a higher overall percentile ranking. This comparison is not about a single winner; it is about understanding which GPU’s strengths align with your specific workload.

Head-to-Head Benchmarks

The direct comparison in the FACT PACK includes two benchmark tests, and the Intel Arc A770 wins both. In Geekbench OpenCL, the Arc A770 scores 109,175 against the RTX A4500 Mobile’s 105,307, a margin of 3.5%. That is a modest lead, suggesting the two cards are broadly comparable in raw compute tasks that scale well across shading units. The RTX A4500 Mobile’s higher shading unit count (5888 vs 4096) is not enough to overcome the Arc A770’s higher clock speeds in this particular test.

The gap widens significantly in Geekbench Vulkan. Here, the Arc A770 scores 94,284, while the RTX A4500 Mobile trails at 76,960 — a delta of 18.4% in Intel’s favor. This is a substantial difference. Vulkan is a low-level API that often rewards higher fill rates and better driver optimization for draw call overhead. The Arc A770’s pixel rate of 307.2 GPixel/s versus the RTX A4500 Mobile’s 144.0 GPixel/s likely explains much of this advantage. The RTX A4500 Mobile’s average benchmark score of 91,134, however, is higher than the Arc A770’s 68,809, because the NVIDIA card has more benchmark entries in its record, including a strong OpenCL result that pulls its average up.

In the overall percentile ranking, the RTX A4500 Mobile sits in the 93rd percentile of all GPUs, while the Arc A770 sits in the 90th. This tells a different story than the head-to-head wins. The NVIDIA card’s nearest rivals include the desktop RTX A4500 (0.6% lower average score) and AMD Radeon Instinct MI60 (1.4% higher), placing it in a professional workstation class. The Arc A770’s nearest rivals are the NVIDIA CMP 90HX (0.3% lower) and AMD Radeon Instinct MI25 (0.4% higher), suggesting it competes in a more mixed mining and compute segment. The head-to-head results favor Intel, but the percentile data suggests NVIDIA’s card has a broader performance profile across a wider range of tests.

Architecture Differences

The architectural split between these two GPUs is stark. The RTX A4500 Mobile uses NVIDIA’s GA104 chip on the Ampere architecture, built on an 8 nm process at Samsung. It packs 17,400 million transistors into a 392 mm² die, yielding a transistor density of 44.4M per mm². The Arc A770 uses Intel’s DG2-512 chip on the Xe-HPG architecture, fabricated on a 6 nm process at TSMC. This die is larger at 406 mm² and holds 21,700 million transistors, for a density of 53.4M per mm². The Intel chip is more densely packed, which contributes to its higher clock speeds.

Clock behavior differs dramatically. The RTX A4500 Mobile has a base clock of 930 MHz and a boost clock of 1500 MHz, which is conservative for a mobile part. The Arc A770 runs at a base of 2100 MHz and boosts to 2400 MHz. That 900 MHz boost advantage is enormous and explains why the Arc A770 can outpace the NVIDIA card despite having fewer shading units. Memory is identical in capacity, type, bus width, and bandwidth: 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s. The memory clock is also the same at 2000 MHz with 16 Gbps effective.

Compute resources are where the cards diverge in opposite directions. The RTX A4500 Mobile has 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. The Arc A770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, but no tensor cores listed. The NVIDIA card’s tensor cores give it a distinct advantage for AI and machine learning workloads. The Arc A770 compensates with higher texture and pixel rates: 614.4 GTexel/s and 307.2 GPixel/s versus the NVIDIA card’s 276.0 GTexel/s and 144.0 GPixel/s. FP32 throughput favors Intel at 19.66 TFLOPS versus 17.66 TFLOPS, but FP16 is a different story. The RTX A4500 Mobile delivers 17.66 TFLOPS at 1:1 ratio, while the Arc A770 delivers 39.32 TFLOPS at 2:1 ratio — double the throughput when using packed FP16.

Where Each One Wins

The RTX A4500 Mobile wins in scenarios that rely on its tensor cores and professional pedigree. Its 184 tensor cores support AI acceleration, making it the better choice for workloads like inference, deep learning training, or any application that uses DLSS or similar tensor-based features. The mobile form factor also matters: it draws 140 W and requires no power connectors, with display outputs described as "portable device dependent." This is a GPU designed to be integrated into a laptop, where power efficiency and thermal management are critical. The data shows it holds a 93rd percentile ranking, which reflects strength across a diverse set of benchmarks beyond the two head-to-head tests.

The Arc A770 wins in raw rasterization and compute throughput. Its higher pixel rate of 307.2 GPixel/s makes it superior for high-resolution rendering, especially in Vulkan-based games or applications that leverage direct draw calls. The FP16 performance of 39.32 TFLOPS is a major asset for workloads that support packed math, such as certain rendering pipelines or scientific compute tasks. The dual-slot design, 225 W TDP, and 1x 6-pin + 1x 8-pin power connectors indicate it is a desktop card meant to be plugged into a full system. Its 90th percentile ranking is lower than the NVIDIA card, but its head-to-head wins show it is no slouch in specific tests.

Where each wins also depends on the software ecosystem. The RTX A4500 Mobile’s Ampere architecture and tensor cores align with NVIDIA’s CUDA ecosystem, which dominates professional and academic computing. The Arc A770’s Xe-HPG architecture is newer and has less established software support, but its Vulkan score of 94,284 suggests strong low-level API performance. For a user on Linux or in a Vulkan-centric environment, the Intel card may be the better bet.

The Verdict

The data points to a simple conclusion for desktop gamers and Vulkan-focused users: the Intel Arc A770 is the stronger pick. It wins both head-to-head benchmarks, delivers nearly double the FP16 throughput, and has a massive clock speed advantage. Its 225 W TDP and dual-slot design are acceptable for a desktop build, and the 329 USD launch MSRP is a data point that speaks for itself. If your workload is gaming, high-refresh rasterization, or anything that uses Vulkan, the Arc A770’s 94,284 Vulkan score and 307.2 GPixel/s pixel rate will serve you better.

The NVIDIA RTX A4500 Mobile is the better choice for mobile workstations and AI-accelerated tasks. Its 184 tensor cores are a feature the Arc A770 simply lacks, making it the only option here for tensor-based workloads like DLSS or machine learning inference. The 140 W TDP and no power connector requirement make it feasible in a laptop chassis, and its 93rd percentile ranking suggests it performs well across a broader range of applications than the Arc A770. Its lower clock speeds hurt it in the head-to-head tests, but the overall average score of 91,134 is higher than the Intel card’s 68,809, indicating more consistent performance across many benchmarks.

Do not buy the Arc A770 if you need tensor cores. Do not buy the RTX A4500 Mobile if you need a desktop card with high pixel throughput. The choice is clear: Intel wins on raw speed and price, NVIDIA wins on features and mobility. The 18.4% Vulkan gap is the decisive number — if your software uses that API, the Arc A770 is the data-backed winner. If your software uses CUDA or tensor cores, the RTX A4500 Mobile is your only choice.
