Intel Arc A380E x2 vs Intel Arc B770 Comparison

The database pairs the Intel Arc A380E x2 against the Intel Arc B770, two Intel GPUs from different architecture generations. The A380E x2 is an Alchemist-generation Xe-HPG part built on TSMC 6 nm with the DG2-128 chip. The B770 is a Battlemage-generation Xe2-HPG part built on TSMC 5 nm with the BMG-G31 chip. Neither entry has recorded benchmark scores: both show an average benchmark score of 0 and a 50th percentile standing against all GPUs. The comparison below therefore relies on the recorded specification fields and their listed rates.

The Verdict

The recorded data assigns the two entries to different roles. The B770 carries the heavier compute specification: 4096 shading units, 256 TMUs, 128 ROPs, 32 RT cores, 16 GB of GDDR6 on a 256-bit bus, 512.0 GB/s of memory bandwidth, 19.66 TFLOPS of FP32, and 39.32 TFLOPS of FP16. The A380E x2 counters with a 130 W TDP, a single-slot profile, and 8x mini-DisplayPort 2.0 outputs. For workloads that scale with shading units, memory capacity, or bandwidth, the data points to the B770. For multi-display output walls or power-constrained installations, the A380E x2 is the entry with the required display density and lower power envelope.

Where Each One Wins

The database records 0 head-to-head benchmark wins for either entry, so the wins below are specification wins. The B770 wins every compute and memory field: shading units 4096 against 1024, RT cores 32 against 8, memory 16 GB against 6 GB, bandwidth 512.0 GB/s against 186.0 GB/s, FP32 19.66 TFLOPS against 4.096 TFLOPS, FP16 39.32 TFLOPS against 8.192 TFLOPS, pixel rate 307.2 GPixel/s against 64.00 GPixel/s, and texture rate 614.4 GTexel/s against 128.0 GTexel/s. The A380E x2 wins the power and physical fields: TDP 130 W against 225 W, suggested PSU 300 W against 550 W, single-slot against dual-slot, and 8x mini-DisplayPort 2.0 against 1x HDMI 2.1a with 3x DisplayPort 2.1. The use-case split follows directly: the B770 suits compute and large-frame-buffer tasks, while the A380E x2 suits multi-screen output and compact low-power systems.

Architecture Differences

The two entries represent successive Intel architectures. The A380E x2 uses Xe-HPG, the architecture behind the Alchemist generation (Arc 3), while the B770 uses Xe2-HPG, the Battlemage generation (Arc 7). The silicon differs accordingly: DG2-128 versus BMG-G31. The A380E x2 is manufactured on TSMC 6 nm with a 157 mm² die and 7,200 million transistors, for a transistor density of 45.9M / mm². The B770 uses TSMC 5 nm with a 368 mm² die; its transistor count is unknown. Execution resources scale from 1024 to 4096 shading units, from 64 to 256 TMUs, from 32 to 128 ROPs, and from 8 to 32 RT cores. The B770 also raises clocks, with a 2100 MHz base and 2400 MHz boost against a flat 2000 MHz for the A380E x2. Memory architecture changes from 6 GB on a 96-bit bus to 16 GB on a 256-bit bus, lifting bandwidth from 186.0 GB/s to 512.0 GB/s. The B770 moves to a PCIe 4.0 x16 interface while the A380E x2 stays at PCIe 4.0 x8. Power delivery expands from a single 6-pin connector and 130 W TDP to a 6-pin plus 8-pin configuration and 225 W TDP. Display output also shifts: the A380E x2 provides 8x mini-DisplayPort 2.0, while the B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. Both entries list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A380E x2 lists Xe Graphics as its predecessor and Battlemage as its successor; the B770 lists Alchemist as its predecessor.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, so no executed frame-rate or compute scores exist for this pairing. The closest recorded measurements are the specification throughput rates. In FP32 compute, the B770 posts 19.66 TFLOPS against the A380E x2's 4.096 TFLOPS. In FP16, the B770 posts 39.32 TFLOPS against 8.192 TFLOPS. Rasterization rates follow the same pattern: pixel rate is 307.2 GPixel/s on the B770 versus 64.00 GPixel/s on the A380E x2, and texture rate is 614.4 GTexel/s versus 128.0 GTexel/s. Memory bandwidth is 512.0 GB/s versus 186.0 GB/s. The A380E x2's largest counterpoints are not throughput but power and display: its 130 W TDP is lower than 225 W, and its 8x mini-DisplayPort 2.0 output set exceeds the B770's 1x HDMI 2.1a and 3x DisplayPort 2.1. Both entries share a 50th percentile standing in the database, which indicates that the specification gap does not translate into a different class ranking.
