Intel Arc B580 vs Arc A750: Which is the best budget gaming GPU?

The Intel Arc B580 was released on December 12, 2024, to take the budget graphics card market head-on. It is designed with Intel's new Battlemage architecture, which brings massive performance improvements over its predecessor, the Alchemist architecture. The Arc B580 is the direct successor to the Arc A580.

However, due to the massive performance improvements accompanying the latest generation, Intel claims the new Arc GPU can even beat the Arc A750, which has a significantly higher number of shader cores and power budget.

In this article, we will put this claim to the test and find out if the Intel Arc B580 can actually rival the Arc A750.

Intel Arc B580 vs Arc A750: Detailed comparison

Both Intel Arc B580 and Arc A750 bring decent performance for 1080p gaming. However, the performance of the latter is still quite inconsistent in some titles, and it remains to be seen if the former can deliver a better result on those. Let's look at the specs of the two GPUs to get a better idea of the hardware powering them.

Specs comparison

Here are the specs of the Arc B580 and Arc A750:

Specifications	Intel Arc B580	Intel Arc A750
Architecture	Xe2 Battlemage	Xe Alchemist
Shader cores	2560	3584
RT cores	20	28
TMUs	160	224
ROPs	80	112
Base core clock speeds	2670 MHz	1720 MHz
Boost core clock speeds	2670 MHz	2400 MHz
Memory capacity	12 GB GDDR6	8 GB GDDR6
Memory bus width	192-bit	256-bit
Memory bandwidth	456 GB/s	512 GB/s
Manufacturing node	5nm	6nm
Thermal design power (TDPs)	190W	225W
Price	$249	$289

Judging by the specs, you would think the older Arc A750 is the better GPU since it has 40% higher shader cores and higher memory bandwidth. However, we have seen time and time again that specs don't always translate into real-world performance.

The new Arc B580 is powered by the new Xe 2 Battlemage architecture, which is supposed to bring around a 50 - 60% improvement in performance over the preceding generation. That could be enough to bridge the gap between the shader cores of the two GPUs. Not to mention, the Arc B580 has higher clock speeds and more memory.

Newer games like Last of Us: Part 1, Indiana Jones and the Great Circle, and Dragon Age: Veilguard require more than 8 GB of video memory, which the Arc A750 doesn't have. It can cause performance issues in the Arc A750, which the Arc B580 will be immune to as it has 12GB of VRAM.

Now that we are done with the specs, it's time to see how Arc B580 and Arc A750 perform in real-world gaming tests. Both GPUs will be tested in multiple titles to properly evaluate their performance.

Here's how the two graphics cards perform in gaming:

Games	Intel Arc B580	Intel Arc A750
Doom Eternal	156 FPS	102 FPS
Ghostwire Tokyo	157 FPS	120 FPS
God of War Ragnarok	110 FPS	92 FPS
Death Stranding	153 FPS	121 FPS
The Witcher Wild Hunt (Next Gen)	103 FPS	80 FPS
Starfield	56 FPS	40 FPS
Red Dead Redemption 2	136 FPS	72 FPS
Cyberpunk 2077	77 FPS	59 FPS
Horizon Forbidden West	83 FPS	49 FPS

Note: The two GPUs were tested at 1080p resolution with High/Ultra graphics settings and/or upscaling technology where necessary. All the FPS numbers have been sourced from the Intel Arc Testing channel on YouTube.

The new Intel Arc B580 delivered 40% more FPS than the Arc A750 on average in a broad range of titles. This is surprising, considering the former has 40% fewer shader cores.

The extent of the performance gap between the two GPUs varies from title to title. Nonetheless, per the above comparison, the Intel Arc B580 generally delivers more FPS than the Intel Arc A750.

The Arc B580 was released for just $249, while the Arc A750 was originally launched at $269. However, the latter's price has come down a lot since its release two years ago, and the GPU is currently available for as low as $189.

Final verdict of Intel Arc B580 vs Arc A750

The Arc B580 essentially costs around 32% more than the Arc A750 (currently), but it delivers 40% more performance on average. The former also has 12GB VRAM compared to 8GB in the other model.

On top of it, the new Intel GPU also has many architectural improvements that will benefit future games. As such, the Intel Arc B580 is the clear winner here.
