GTX 1080 vs Arc A750: Key Differences Explained

The Arc A750 is the better pick for a modern gaming PC with Resizable BAR support: it is generally faster in current DirectX 12 and Vulkan games, has hardware ray tracing and XeSS, and still receives active driver updates. The GTX 1080 remains the safer choice only for older systems without Resizable BAR or for players who mainly run older DirectX 9 and DirectX 11 games, where Pascal’s mature drivers still give it an edge.

Six Years Apart, Similar Market Position Today

The GTX 1080 launched in May 2016 at $599 as NVIDIA’s Pascal flagship before the 1080 Ti arrived. The Arc A750 launched in October 2022 at $289 as part of Intel’s first-generation Alchemist lineup. In 2026 both are budget used cards, and Intel’s current Arc B570 and B580 have replaced the A750 in new-card shelves. Buyers usually face this matchup when looking for cheap 1080p performance.

Specs Side by Side

On paper, the A750 has 60% more memory bandwidth, eight times the L2 cache and much higher clocks. The catch is software: Intel’s first-generation drivers were rough at launch, and performance varies far more from game to game than it does on the GTX 1080.

Real-World Gaming Performance

Modern DirectX 12 and Vulkan Titles

Reviews from Tom’s Hardware, TechSpot/Hardware Unboxed and PCWorld placed the Arc A750 around RTX 3060 level in modern DX12 games, which puts it ahead of the GTX 1080 by roughly 10-25% in those titles. Synthetic tests such as 3DMark Fire Strike also favor the A750 by a wide margin. In newer releases that lean on modern APIs, the A750 is the stronger card.

Older DirectX 9 and DirectX 11 Games

This is where the GTX 1080 fights back. Intel acknowledged at launch that Arc’s DX11 performance lagged rivals, and reviewers found large drops in older titles. Later drivers improved DX9 and DX11 performance significantly, with Intel citing double-digit average gains, but TechSpot’s re-review found gains were uneven outside the titles Intel highlighted. Some aggregated benchmark suites weighted toward older games even show the GTX 1080 ahead overall. The honest summary: the A750 tends to win in new games, while the GTX 1080 is more consistent in older ones.

As an approximate guide that varies with settings, CPU, driver version and patch, both cards typically land in the 50-90 fps range at 1080p high in moderately demanding games, with the A750 toward the upper end in DX12 titles and the GTX 1080 more stable in DX11 titles.

Ray Tracing and Upscaling

The GTX 1080 has no ray tracing hardware and cannot run games that require it, such as Indiana Jones and the Great Circle or Doom: The Dark Ages. The Arc A750 has dedicated ray tracing units and performs respectably for its class with light RT settings.

For upscaling, the A750 supports XeSS running on its XMX matrix engines, which gives better image quality than the generic XeSS path, and Intel has extended XeSS 2 frame generation support to Alchemist cards in supported games. The GTX 1080 cannot use DLSS because it has no Tensor cores, so it relies on FSR 2/3 or XeSS’s fallback mode.

The Resizable BAR Requirement

This point decides many purchases. The Arc A750 needs Resizable BAR enabled to perform properly, and reviews showed severe drops, in the worst cases over 50%, without it. Resizable BAR is generally available on Intel 10th/11th-gen and newer and AMD Ryzen 3000 and newer platforms with updated BIOS. If your motherboard lacks it, the GTX 1080 is the better choice, full stop.

Driver Support Going Forward

NVIDIA has announced that the 580 driver branch is the last to bring Game Ready support for Pascal, with only security updates for a limited period afterward. The GTX 1080 will not get optimizations for new games. Intel continues to update Arc drivers, and A-series cards share much of the driver stack with current Battlemage cards, so the A750 is likely to keep improving in new releases.

Power and PSU

The A750 is rated at 225 W versus 180 W for the GTX 1080, and Arc cards also have relatively high idle power draw unless ASPM settings are configured. Sizing with GPU TDP + CPU + about 150 W headroom and a 125 W CPU:

• GTX 1080: 180 + 125 + 150 = 455 W, so a quality 500-550 W PSU works.
• Arc A750: 225 + 125 + 150 = 500 W, so a quality 550-600 W PSU is the safer target.

The GTX 1080 needs one 8-pin connector; the A750 Limited Edition needs one 6-pin plus one 8-pin. Both are 2-slot cards. The GTX 1080 reference is 267 mm; A750 lengths vary by model but most fit standard mid-towers.

Value Calculation

Using modern-game performance, set the GTX 1080 at 100 and the A750 at roughly 117 (midpoint of the 10-25% range).

• At launch: GTX 1080 $599 / 100 = $5.99 per point; A750 $289 / 117 = about $2.47 per point.
• Used, with a GTX 1080 usually $80-$120 and an A750 usually $130-$180: $100 / 100 = $1.00 per point versus $155 / 117 = about $1.32 per point.

The GTX 1080 is cheaper per frame used, but the A750 includes ray tracing, XeSS on XMX hardware, AV1 encoding and continued driver support. For a new-card budget near $200-$250, the Arc B570 or B580 is worth checking, as Battlemage fixed many Alchemist weaknesses.

Decision Guide

Used Buying Notes

Any GTX 1080 is now at least eight years old. Check fan bearings, temperatures and thermal paste condition, and expect some cards to need maintenance. Arc A750 units are younger, but confirm the seller’s system had Resizable BAR enabled before attributing poor performance to the card. Ask for a quick benchmark run if possible.

Media Engines and Display Outputs

The Arc A750’s media engine is one of its quiet strengths. It supports AV1 hardware encoding and decoding, which lets streamers and video creators get better quality per bitrate than older H.264 encoders. The GTX 1080’s NVENC encoder is capable for H.264 and HEVC but has no AV1 support. On the display side, the A750’s HDMI 2.1 and DisplayPort 2.0 outputs suit modern high-refresh monitors, while the GTX 1080 keeps a dual-link DVI port, useful for some older monitors that lack DisplayPort or HDMI.

Idle power is one area to watch on the A750. Without the right BIOS and Windows power settings, Alchemist cards can draw noticeably more power at idle than competing cards. Enabling ASPM in the BIOS and Windows’ PCI Express link state power management reduces it significantly.

Bottom Line

On a modern platform, the Arc A750 is the more capable and future-proof card, with ray tracing, better upscaling and ongoing drivers. The GTX 1080 still makes sense for older PCs without Resizable BAR and for libraries full of older DX11 games, but its lack of ray tracing hardware and the end of Game Ready drivers limit its future.

Frequently Asked Questions

Is the Arc A750 faster than the GTX 1080?

In modern DX12 and Vulkan games, generally yes, by roughly 10-25% according to major reviews. In older DX9 and DX11 games the GTX 1080 can match or beat it.

Does the Arc A750 work without Resizable BAR?

It works, but performance drops sharply, by over 50% in some games according to reviews. Intel lists Resizable BAR as a requirement for proper performance.

Can the GTX 1080 run games that require ray tracing?

No. Pascal has no ray tracing hardware, so titles that mandate RT, such as Indiana Jones and the Great Circle, will not launch.

Is 8 GB of VRAM enough on these cards?

For 1080p at medium to high settings, 8 GB remains workable. Some recent games need lower texture settings to avoid stutter, and both cards share this limit.

What PSU does the Arc A750 need?

A quality 550-600 W unit is a comfortable choice with a mainstream CPU. The Limited Edition card uses one 6-pin and one 8-pin connector.
