Upgrading From Arc A580 to Arc B570: What You Actually Gain

Moving from the Arc A580 to the Arc B570 gets you roughly 27% more performance at 1080p according to TechPowerUp’s review data, plus 2 GB more VRAM, lower power draw and a simpler single 8-pin connection, so it is a reasonable upgrade for 1080p gamers who are starting to drop below 60 FPS. If your A580 still handles your games comfortably, or you want a bigger leap for 1440p, it is better to save for a stronger card.

Both cards come from Intel, use the same driver package and share most software features, which makes this one of the simplest GPU swaps you can do. The question is whether a mid-20s percentage gain is worth the money. Let’s look at what actually changes.

Spec Sheet: A580 Versus B570

The B570 has fewer shader units and less bandwidth, but it runs 500 MHz faster and uses Intel’s much more efficient Battlemage design. Battlemage keeps its execution units busier and handles modern workloads far better than Alchemist, which is why a numerically smaller chip comes out well ahead.

The Gains, Game by Game Type

Modern AAA at 1080p

TechPowerUp’s B570 reviews measured an average uplift of about 27% over the A580 at 1080p. That is the headline number for this upgrade and it holds up across most modern DirectX 12 titles. In approximate terms, a game that runs at 45–50 FPS on high settings on the A580 will often land around 57–64 FPS on the B570, which can be the difference between dropping settings and staying above 60. Those figures vary with game, settings, CPU and driver version.

Games that exceed 8 GB

Some recent releases at high textures push past 8 GB even at 1080p. In those games, the A580 stutters or swaps in low-resolution textures, while the B570’s 10 GB keeps more assets in memory. The real-world gain here can be larger than the average suggests, mostly in smoothness and 1% lows rather than average FPS.

1440p

At 1440p the A580’s wide 256-bit bus partly offsets its weaker core, so the B570’s percentage lead shrinks a little. Neither card is a strong 1440p performer in new AAA games; the B570 can manage 1440p with XeSS upscaling and medium-high settings in many titles.

Esports and older titles

In lighter esports games, both cards often produce high frame rates where the CPU becomes the limit. Battlemage’s driver behavior in older DX11 titles is generally more consistent than Alchemist’s at launch, but the gain in competitive shooters depends more on your CPU than this GPU swap.

Features You Already Have (and the Few You Gain)

Intel brought XeSS 2 to both generations, so A580 owners already have XeSS Super Resolution, XeSS Frame Generation and Xe Low Latency in supported games, plus hardware AV1 encoding. You are not unlocking a new upscaler with this upgrade. What you gain is:

• A faster base frame rate, which makes XeSS Frame Generation feel better (frame generation works best above roughly 50–60 FPS before generation).
• Extra VRAM for frame generation’s memory overhead.
• Battlemage’s improved ray tracing units, which hold up better than Alchemist’s in lighter RT effects.
• DisplayPort 2.1 outputs instead of DisplayPort 2.0.

VRAM Planning: 8 GB to 10 GB

A practical way to judge whether 10 GB is enough for you:

• 1080p, medium–high settings: about 6–8 GB in most current games. Both cards are fine.
• 1080p, ultra textures or RT: about 8–10 GB. The B570 fits; the A580 often does not.
• 1440p, high settings: about 9–12 GB. The B570 is workable with sensible settings.

Power and Cabling

The B570 lowers rated power from 175 W to 150 W and cuts the connector requirement from two 8-pin plugs to one. That second point helps owners of budget power supplies that only provide one PCIe lead or rely on adapters.

PSU estimate using GPU TDP + CPU + about 150 W headroom, with a typical 65 W-class CPU drawing around 90 W in games:

If your A580 runs on a quality 500 W or larger unit, the B570 is a drop-in swap with no PSU change needed.

Physical Fit

Both cards are dual-slot. The B570 reference design is 272 mm long, and partner models range from compact dual-fan to larger triple-fan coolers. Check your case’s maximum GPU length; if your A580 fits with room to spare, most dual-fan B570 models will too.

Platform Checks Before You Swap

• Resizable BAR: required for good performance on both cards. Since you run an A580 already, it is likely enabled.
• PCIe lanes: the A580 uses x16, the B570 uses x8. On PCIe 3.0 motherboards the B570 has half the bus bandwidth, which matters most if VRAM fills. On PCIe 4.0 boards, the difference is negligible.
• CPU: Hardware Unboxed found Battlemage cards are more sensitive to slow CPUs than NVIDIA or AMD cards. With a Ryzen 5 2600/3600 or Intel 9th-gen Core i5, expect part of the 27% uplift to disappear in CPU-heavy games.

Selling Your A580 the Smart Way

Because the A580 is a budget card, its resale value is modest, so the way you sell it affects your net upgrade cost noticeably. Keep the original box and any included accessories, clean the heatsink and fans, and run a short stress test so you can show buyers stable temperatures and clocks. Make clear in the listing that the card needs Resizable BAR, since buyers with older systems may not know this and could return it. Listing locally avoids shipping risk and fees. Timing helps too: selling shortly after you install the B570 means you are not paying for two cards for long, and older Arc cards tend to lose value steadily as newer budget models arrive.

Cost-per-Gain Worked Example

Used A580 cards typically sell for roughly $100–$140. If you buy a B570 near its $219 launch price and sell the A580 for about $120, your net cost is around $100. For roughly 27% more 1080p performance, that comes to about $3.70 per percentage point of uplift. That is decent value for a budget upgrade, and noticeably better than the A750-to-B570 path, where the gain is smaller.

For comparison, TechPowerUp measured the Arc B580 around 15% faster than the B570. If its price is within about $30–$40 of the B570 where you shop, the B580 gives a bigger total jump over the A580, plus 12 GB of VRAM.

Who Should Upgrade?

Frequently Asked Questions

How much faster is the Arc B570 than the Arc A580?

TechPowerUp’s review data shows an average uplift of about 27% at 1080p. The gain can be larger in games that exceed 8 GB of VRAM. At 1440p the gap narrows slightly because the A580 has a wider memory bus.

Will the B570 work in my current A580 system?

In nearly all cases, yes. It needs Resizable BAR, which you should already have enabled for the A580, and only one 8-pin power connector. Install the latest Intel graphics driver before or right after the swap.

Does the Arc A580 support XeSS 2 frame generation?

Yes. Intel made XeSS 2, including Frame Generation and Xe Low Latency, available on Alchemist cards as well as Battlemage. Upgrading to the B570 improves the base frame rate that frame generation builds on, but does not unlock a new feature tier.

Should I get the B580 instead of the B570?

If the price difference is small, the B580 is the better long-term pick. It is around 15% faster than the B570 according to TechPowerUp and has 12 GB of VRAM. The B570 makes more sense when budget is tight.

Is the A580 still good enough for 1080p?

For esports and older games, yes. In newer AAA titles it increasingly requires medium settings and XeSS to stay near 60 FPS. If that trade-off bothers you, the B570 is an affordable step up.
