Architecture Differences

The Intel Arc B770 and the Intel Arc Graphics 112EU Mobile represent two distinct design philosophies within Intel's graphics lineup. The B770 is built on the Xe2-HPG architecture, fabricated by TSMC on a 5 nm process, and belongs to the Battlemage (Arc 7) generation. The 112EU Mobile uses the older Xe-LPG architecture, built on Intel's own 10 nm process, and comes from the Arc Graphics-M (Meteor Lake) generation. This difference in process node alone accounts for significant disparities in transistor density and power efficiency, though the exact transistor counts are not recorded for either product.

The B770's die size is listed at 368 mm², a substantial physical footprint for a desktop discrete GPU. The 112EU Mobile has no recorded die size, which is typical for an integrated processor where the graphics die is combined with CPU cores on a single package. The B770 uses a PCIe 4.0 x16 bus interface for maximum bandwidth to the host system, while the 112EU Mobile connects via a Ring Bus, a design choice that reduces latency but ties memory access to the system's shared memory architecture.

Compute resources differ dramatically. The B770 packs 4096 shading units, 256 texture mapping units, and 128 raster output pipelines. It also includes 32 dedicated ray tracing cores. The 112EU Mobile has 896 shading units, 56 TMUs, and 24 ROPs, with no ray tracing cores listed. The B770's pixel rate is 307.2 GPixel/s versus 52.80 GPixel/s for the mobile part. Texture rate follows the same pattern: 614.4 GTexel/s versus 123.2 GTexel/s.

The memory architecture is a fundamental divergence. The B770 has a dedicated 16 GB GDDR6 frame buffer on a 256-bit bus, providing 512.0 GB/s of bandwidth. The 112EU Mobile uses System Shared memory throughout, with bandwidth described as "System Dependent." This means the integrated GPU's performance scales with the host system's memory speed and configuration, a variable that does not affect the discrete B770.

Clock behavior also differs. The B770 runs at a 2100 MHz base clock with a 2400 MHz boost. The 112EU Mobile has a 300 MHz base clock and a 2200 MHz boost. The low base clock on the mobile part suggests aggressive power saving when idle, ramping up to near the discrete card's boost speed under load.

The Verdict

The recorded data shows two products aimed at entirely different use cases. The Intel Arc B770 is a high-performance discrete desktop GPU designed for demanding workloads. Its 16 GB of dedicated GDDR6 memory, 4096 shading units, and 19.66 TFLOPS FP32 performance position it as a serious contender for gaming and content creation on desktop systems. The 225 W TDP and 550 W suggested PSU requirement confirm this is a card built for full-sized towers with adequate power delivery.

The Intel Arc Graphics 112EU Mobile is an integrated solution for laptops and compact devices. Its 65 W TDP, lack of dedicated memory, and 896 shading units make it suitable for everyday computing, light gaming, and media playback. The absence of ray tracing cores and the lower DirectX feature level (12_1 versus 12_2) further indicate it is not intended for high-end gaming or professional ray-traced workloads.

Benchmark data shows both products occupy the 50th percentile against all GPUs, though neither has specific head-to-head scores or rival data recorded in the database. The architectural differences are so pronounced that a direct comparison serves primarily to highlight the gap between integrated and discrete graphics. Users needing maximum performance should choose the B770. Users prioritizing portability and low power draw should select a system with the 112EU Mobile. The data does not support any other conclusion.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores between the Intel Arc B770 and the Intel Arc Graphics 112EU Mobile. Both products show an average benchmark score of 0 and an identical 50th percentile versus all GPUs. This lack of direct comparative data means the analysis must rely on the architectural specifications and theoretical performance figures recorded in the database.

The most significant performance indicator is FP32 throughput. The B770 delivers 19.66 TFLOPS, which is exactly 5 times the 3.942 TFLOPS of the 112EU Mobile. This ratio holds across other compute metrics. The B770's pixel rate of 307.2 GPixel/s is 5.8 times higher than the 52.80 GPixel/s of the mobile part. Texture rate shows a similar gap: 614.4 GTexel/s versus 123.2 GTexel/s, a factor of 5.0.

Memory bandwidth is where the gap becomes extreme. The B770's 512.0 GB/s dedicated bandwidth cannot be directly compared to the "System Dependent" bandwidth of the 112EU Mobile, but any system shared memory configuration will face contention with CPU workloads. In practical terms, the B770's 16 GB GDDR6 on a 256-bit bus provides predictable, consistent memory performance, while the 112EU Mobile's performance varies with system configuration.

Ray tracing capability further separates the two. The B770 has 32 dedicated ray tracing cores, while the 112EU Mobile has none recorded. Combined with the DirectX 12 Ultimate (12_2) support on the B770 versus DirectX 12 (12_1) on the mobile part, this indicates the B770 can handle hardware-accelerated ray tracing workloads that the 112EU Mobile cannot.

The FP16 performance numbers follow the same pattern: 39.32 TFLOPS on the B770 versus 7.885 TFLOPS on the 112EU Mobile, both with a 2:1 ratio to FP32. This suggests both architectures handle mixed-precision workloads similarly, but the B770 does so at 5 times the scale.

Where Each One Wins

The Intel Arc B770 wins in every recorded performance category. It has more shading units, higher clocks, dedicated memory, ray tracing hardware, and higher theoretical throughput across pixel rate, texture rate, FP32, and FP16. The data supports its use for gaming at high resolutions, 3D rendering, video editing, and any workload that benefits from large dedicated memory pools and high bandwidth. The 512.0 GB/s bandwidth and 16 GB capacity allow it to handle large textures and complex scenes without memory swapping. The 32 ray tracing cores deliver hardware acceleration for realistic lighting effects in supported titles.

The Intel Arc Graphics 112EU Mobile wins in power efficiency and portability. Its 65 W TDP is less than one third of the B770's 225 W TDP. It requires no external power connectors and no dedicated PSU, making it suitable for thin laptops and compact systems. The Ring Bus interface integrates directly with the host processor, eliminating the need for a discrete PCIe connection. Its 300 MHz base clock indicates excellent idle power characteristics, extending battery life when performing light tasks.

The 112EU Mobile also holds an advantage in system cost by virtue of being integrated, though the database records no pricing information for either product. Its release date of 2023-12-13 means it has a longer presence in the market compared to the B770's 2025-12-31 release.

For users with a desktop system and a 550 W PSU, the B770 is the clear choice based on the data. For users needing a laptop that can handle occasional gaming without draining the battery, the 112EU Mobile provides a reasonable baseline. The 50th percentile ranking for both products against all GPUs suggests each performs adequately within its respective class, but the specification gap between them is too large to bridge in any workload.
