Key takeaways
- Arc A750 with a 105 W CPU: 225 + 105 + 150 = 480 W, so a quality 550-600 W unit is recommended.
- Arc A580 with a 105 W CPU: 175 + 105 + 150 = 430 W, so a quality 500 W unit is enough.
No, you should not move from an Arc A750 to an Arc A580: the A580 is a cut-down version of the same chip and is roughly 5-15% slower in games, with the same 8 GB of VRAM and the same feature set. The only things you gain are about 50 W lower rated power and a slightly cooler, quieter card. If you own an A750 and want more performance, look at an Arc B580, RX 9060 XT 16GB or RTX 5060 Ti 16GB instead. If you are choosing between the two from scratch, buy the A750 unless the A580 is significantly cheaper.
Both cards use Intel’s first-generation Alchemist architecture and the same ACM-G10 silicon. The A750 launched in October 2022 at $289. The A580 followed in October 2023 as a lower-cost option with fewer active Xe cores and lower clocks. In 2026, Intel’s Battlemage cards, the Arc B570 and B580, are the current generation, so both Alchemist models are now mostly found used or as remaining stock.

The A750 has about 17% more shading units, a 400 MHz higher boost clock and twice the L2 cache. Memory capacity, bus width and bandwidth are identical. In other words, the A580 is the same memory subsystem with less compute in front of it, so it trails in games while drawing less power.
Performance: What You Give Up
Raster
GamersNexus’ A580 review measured the A750 ahead by about 5% in Shadow of the Tomb Raider at 1080p, about 9% in F1 22 at 1440p and about 15% in Baldur’s Gate 3. TechPowerUp’s A580 review data puts the A750 roughly 9% ahead on average. Benchmark aggregators range from about 5% to the high teens. A fair summary is that the A750 is about 5-15% faster, with the gap tending to grow at higher resolutions and in GPU-heavy titles.
As an example, if an A750 runs a game at around 66 FPS at 1080p high, the A580 would likely land around 57-63 FPS. Both comfortably handle 1080p high in most games, while 1440p in new AAA titles needs medium settings and upscaling on either card. Numbers vary with settings, CPU, game patches and drivers.
Ray tracing
The same architecture means similar RT behavior, scaled by compute. GamersNexus measured the A750 about 14% ahead in F1 22 with ray tracing enabled. Light RT at 1080p with XeSS is possible on both, but the A750 has more headroom.
Upscaling and frame generation
Feature support is identical. Both cards run XeSS on XMX matrix units, and XeSS 2 adds frame generation and low-latency mode in supported games. Both can also use FSR 3.1. DLSS is NVIDIA-only. Since features are the same, the only difference you will feel is raw performance.
What You Gain: Power and Heat
The A580 is rated at 175 W versus 225 W for the A750. That 50 W reduction means a slightly cooler, quieter card under load and a bit less heat in the case. Both cards share Alchemist’s high idle power at default settings, as reviews including TechPowerUp’s noted, so there is little difference at the desktop unless ASPM is enabled on both.
PSU sizing with GPU TDP plus CPU power plus about 150 W of headroom:
- Arc A750 with a 105 W CPU: 225 + 105 + 150 = 480 W, so a quality 550-600 W unit is recommended.
- Arc A580 with a 105 W CPU: 175 + 105 + 150 = 430 W, so a quality 500 W unit is enough.
Connectors differ slightly. The A750 reference design uses one 6-pin plus one 8-pin, while the A580 uses two 8-pin plugs. Both need two PCIe power leads.
Upgrade Decision Table
| Your situation | Recommendation |
|---|---|
| You own an A750 and want more FPS | Do not switch to A580; consider Arc B580, RX 9060 XT 16GB or RTX 5060 Ti 16GB |
| You own an A750 and your PSU is struggling | A580 is a valid sidegrade, but a PSU upgrade is usually smarter |
| Buying new or used, both similar price | Arc A750 |
| Buying, A580 at least 15-20% cheaper | Arc A580 offers comparable value per frame |
| Small case with limited airflow | Arc A580 for lower heat output |
| Targeting 1440p | Arc A750, or better, a 12-16 GB current card |
Value Math
Using a performance index where the A580 is 100 and the A750 is about 110 (the middle of the 5-15% range), the A750 delivers better value whenever it costs less than about 1.1 times the A580’s price. Used prices for both overlap heavily: the A750 commonly sells in a broad range of roughly $130-$170, and the A580 roughly $110-$150. At $150 for an A750 versus $130 for an A580, the price ratio is about 1.15, so the two are close to equal on cost per frame and the A750’s extra performance tips the balance. At $160 versus $120, the ratio is about 1.33 and the A580 becomes better value.
For an A750 owner, swapping to an A580 costs money and time and returns lower performance. There is no scenario where that trade makes sense purely for gaming.
Platform Notes
Both cards require Resizable BAR for normal performance and use a PCIe 4.0 x16 link, so platform compatibility is identical. Both are 2-slot designs, with length depending on the partner model; Intel’s Limited Edition A750 and partner A580 boards are similar mid-size cards. Display outputs are the same, with HDMI 2.1 and three DisplayPort 2.0 connectors, and both support AV1 hardware encoding.
Driver Maturity and Game Compatibility
Because the two cards share the same architecture and driver package, any compatibility improvement Intel ships applies to both at once. Alchemist’s early weakness in older DirectX 11 and DirectX 9 games has been reduced considerably by driver updates since launch, but performance can still be less consistent than on NVIDIA or AMD cards in older or niche titles. Switching from the A750 to the A580 changes nothing here: any game that runs poorly on your A750 will run the same way, only a little slower, on the A580. If driver consistency is your main frustration, the fix is a move to a different architecture, such as Intel’s newer Battlemage cards or an AMD or NVIDIA model, not a sideways step within Alchemist.
Where to Go From an A750
If the A750 no longer meets your needs, the logical next steps are the Arc B580, which brings Battlemage efficiency, 12 GB of VRAM and stronger performance, or the RX 9060 XT 16GB and RTX 5060 Ti 16GB, which add more performance and 16 GB of memory. Each of those is a real upgrade; the A580 is not.
Verdict
The Arc A580 is a downgrade from the Arc A750, trading 5-15% of performance for 50 W lower rated power. Keep your A750, or move up to a current-generation card if you need more. When buying either used, pick the A750 unless the A580 costs meaningfully less.
Frequently Asked Questions
Is the Arc A580 faster than the Arc A750?
No. The A750 is roughly 5-15% faster, based on GamersNexus and TechPowerUp review data. The A580 uses fewer shading units, lower clocks and half the L2 cache. Memory capacity and bandwidth are the same.
Why would anyone choose the A580 over the A750?
Mainly for price and power. The A580 is often cheaper and is rated at 175 W instead of 225 W. When the price gap is large enough, it can offer similar or better value per frame.
Do both cards support XeSS frame generation?
Yes. Both Alchemist cards support XeSS upscaling on XMX units and XeSS 2 frame generation in supported games. Their feature sets are identical, so only performance differs.
Do the A750 and A580 need Resizable BAR?
Yes. Both cards depend on Resizable BAR for consistent performance. Without it, frame rates drop and stutter increases noticeably. Enable it in your motherboard BIOS before installing either card.
What is a good upgrade from the Arc A750?
The Arc B580, RX 9060 XT 16GB and RTX 5060 Ti 16GB are all meaningful upgrades. They offer more performance, more VRAM and newer features. Choose based on budget and whether you prefer XeSS, FSR 4 or DLSS.
