Intel Arc A380E vs Intel Graphics 24EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc A380E and the Intel Graphics 24EU Mobile. Both entries show zero benchmark scores, zero wins for either side, and no nearest rival comparisons. This means any performance comparison must be derived from the raw specification data rather than measured application results.

The most striking gap appears in raw compute throughput. The Arc A380E delivers 4.096 TFLOPS of FP32 performance, while the Graphics 24EU Mobile manages 384.0 GFLOPS. That places the discrete card at roughly 10.7 times the single-precision compute capability of the integrated part. For FP16 workloads, the ratio holds similarly: 8.192 TFLOPS versus 768.0 GFLOPS, again a 10.7-fold advantage.

Pixel throughput tells a similar story. The Arc A380E outputs 64.00 GPixel/s, while the integrated solution reaches 4.000 GPixel/s, a 16-fold difference. Texture fill rates show a 10.7x gap as well: 128.0 GTexel/s versus 12.00 GTexel/s. These numbers indicate that the Arc A380E is designed for sustained rendering workloads, whereas the Graphics 24EU Mobile is suited only to light display output and basic 2D acceleration.

Memory bandwidth separates the two even further. The Arc A380E has 186.0 GB/s of dedicated GDDR6 bandwidth across a 96-bit bus. The Graphics 24EU Mobile relies on system shared memory, with bandwidth listed as "System Dependent." That dependency means real-world throughput varies with the host platform's memory configuration, but it will never approach the discrete card's dedicated bandwidth. For any memory-heavy task, such as texture streaming or large framebuffers, the Arc A380E holds an insurmountable advantage.

Clock behavior also differs. The Arc A380E runs at a flat 2000 MHz for both base and boost, suggesting a locked, consistent operating point. The Graphics 24EU Mobile idles at 300 MHz and boosts to 1000 MHz, a much lower ceiling that reflects its power-constrained design. The integrated part's boost clock is half the discrete card's sustained clock, which compounds the shading unit and memory advantages.

Architecture Differences

The two GPUs come from different architectural families within Intel's lineup. The Arc A380E uses the Xe-HPG architecture on the DG2-128 chip, belonging to the Alchemist (Arc 3) generation. The Graphics 24EU Mobile uses Xe-LP architecture on the Twin Lake chip, part of the HD Graphics-T (Twin Lake) generation. These are fundamentally different designs: Xe-HPG targets discrete graphics cards with dedicated memory and high throughput, while Xe-LP targets low-power integrated graphics in portable devices.

Manufacturing processes diverge sharply. The Arc A380E is built on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9M per mm². The Graphics 24EU Mobile uses Intel's 10 nm process, with transistor count and die size listed as unknown. The process node difference explains much of the power and performance gap: the discrete chip packs over seven billion transistors, while the integrated part operates within a much smaller thermal envelope.

Execution resources scale accordingly. The Arc A380E has 1024 shading units, 64 texture mapping units, 32 raster output units, and 8 ray tracing cores. The Graphics 24EU Mobile has 192 shading units, 12 TMUs, and 4 ROPs, with no ray tracing cores at all. The presence of dedicated ray tracing hardware on the Arc A380E is a major architectural differentiator, as it enables hardware-accelerated ray-traced effects in DirectX 12 Ultimate titles. The integrated part lists DirectX 12 (12_1) support, which omits the ray tracing and mesh shader features found in the 12_2 feature level of the Arc A380E.

Memory architecture is another fundamental split. The Arc A380E uses 6 GB of GDDR6 on a 96-bit bus with fixed clock speeds. The Graphics 24EU Mobile shares system memory with the CPU, using a Ring Bus interface, and has no dedicated VRAM. This affects not just bandwidth but also latency and capacity allocation, as the integrated GPU must compete with the operating system and applications for memory resources.

Power delivery reflects these differences. The Arc A380E has a 75 W TDP and requires no external power connectors, drawing solely from the PCIe slot. The Graphics 24EU Mobile has a 6 W TDP and operates as an IGP with no slot width or power connector specifications. The 69 W difference in thermal design power shows the discrete card's willingness to spend energy for performance, while the integrated part prioritizes efficiency for battery-powered devices.

Q: How does memory capacity compare?

A: The Arc A380E has 6 GB of dedicated GDDR6 memory with 186.0 GB/s bandwidth. The Graphics 24EU Mobile uses system shared memory with bandwidth described as "System Dependent," meaning it varies with the host platform.

Q: What are the power requirements for each?

A: The Arc A380E has a 75 W TDP with no external power connectors, relying on the PCIe slot, and suggests a 250 W power supply. The Graphics 24EU Mobile has a 6 W TDP and operates as an integrated GPU with no power supply recommendation.

Q: Which API feature levels do they support?

A: The Arc A380E supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Graphics 24EU Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The key difference is the DirectX feature level: 12_2 versus 12_1.

Q: What is the production status of each?

A: The Arc A380E is listed as end-of-life, with a release date of March 2024 and a predecessor of Xe Graphics and successor of Battlemage. The Graphics 24EU Mobile is active, released in December 2024, with no predecessor or successor listed.

Where Each One Wins

The Arc A380E wins decisively in every compute-heavy scenario. Its 1024 shading units, 64 TMUs, and 32 ROPs make it suitable for 3D rendering, gaming at moderate resolutions, and GPU-accelerated content creation. The 8 ray tracing cores enable hardware-accelerated ray-traced lighting effects in compatible titles, something the integrated part cannot do. The 6 GB GDDR6 frame buffer with 186.0 GB/s bandwidth allows it to handle large textures and multiple display outputs simultaneously, with four DisplayPort 2.0 connections supporting multi-monitor setups. The locked 2000 MHz clock ensures consistent performance across workloads without thermal throttling concerns within its 75 W envelope.

The Graphics 24EU Mobile wins in efficiency and deployment flexibility. Its 6 W TDP means it can run passively in fanless designs, drawing minimal power from the host system. The Ring Bus interface integrates directly with the CPU, eliminating the need for a discrete slot or external power. The 300 MHz base clock allows near-zero power draw at idle, making it appropriate for basic display output, video playback, and light office tasks on portable devices. Its active production status and 2024 release date suggest it is the current choice for new low-power mobile platforms. The system shared memory approach removes any VRAM capacity limits, as it can access whatever system memory the host provides, though bandwidth remains constrained.

The Verdict

The data shows two GPUs serving entirely different purposes. The Arc A380E is a discrete graphics card with dedicated 6 GB GDDR6 memory, 1024 shading units, and ray tracing hardware. It delivers 4.096 TFLOPS FP32 performance, 64.00 GPixel/s pixel fill rate, and 128.0 GTexel/s texture rate. It targets users who need real 3D rendering capability, whether for gaming, CAD visualization, or GPU compute tasks, and it does so within a modest 75 W power envelope that requires no external connectors.

The Graphics 24EU Mobile is an integrated GPU with 192 shading units, no ray tracing support, and system shared memory. Its 384.0 GFLOPS FP32 performance and 4.000 GPixel/s pixel rate place it firmly in the territory of basic graphics acceleration. Its 6 W TDP makes it ideal for thin-and-light laptops, mini PCs, and embedded systems where battery life and thermal output matter more than raw performance.

Anyone selecting between these two parts should look at the workload first. For tasks that involve 3D rendering, modern game titles with DirectX 12 Ultimate features, or any GPU compute work, the Arc A380E is the only viable option. Its 10.7x FP32 advantage, 16x pixel rate advantage, and dedicated memory bandwidth leave no contest. For simple display output, video decode, and light productivity on a power-constrained mobile platform, the Graphics 24EU Mobile suffices, and its active production status ensures ongoing availability. The Arc A380E, while end-of-life, remains the stronger performer by every measurable metric in the database.
