Intel's ARC B580 graphics card was very impressed a few months ago, thanks to a truly decent performance and a lot of VRAM at mainstream prices, but until now we have never started reviewing the cheaper B570 models. However, this may not be a bad thing, as it means we can spend some time using this GPU as it wants to use it, understand the idea of usability and do some extra testing on the driver overhead.
We'll get into these things later, but now let's answer a simple question: What is the nominal $220 B570 card separated from the nominal 250 b580? There are not many answers – which makes the B570 perhaps the more attractive of both options.
Specifically, we are looking at dropping from 20 XE cores and RT units to 18, the XMX AI engine rose from 160 to 144, and the core clock dropped by about 6%. The biggest change is the biggest change to the memory subsystem, which shifted from 12GB GDDR6 on a 192-bit bus to 10GB on a 160-bit bus, so the B570 only has 83% bandwidth to the full-fat B580. The power is also greatly reduced, from the rated value of the B570 from 190W to 150W.
These reduced power is proportional to cuts elsewhere, and the test supports this idea. Instead of breaking the results on the following pages, the B570 draws 88% of the power in games like Alan Wake 2, while 87% of the performance of 88% of the features in Senua's Saga: Hellblade 2.
Of course, these results are not present in vacuum, and arc cards in terms of power efficiency are illuminating compared to the closest AMD and NVIDIA equivalents. For example, the NVIDIA RTX 4060 outperforms the B580 in the Alan Wake 2 while attracting 80% of power. Meanwhile, the AMD RX 7600 is the fastest option, accounting for 107% of the B580's average frame rate while consuming 6% of power.
If we look at those Alan Wake 2 in pure-performance terms measured in Joule per frame, the RTX 4060 is the thorough leader in 3.19, followed by the tight combination of the other three cards: AMD at 3.98, B580, at 4.03 and B570, at 4.06. If we look at the RT performance of Avatar: Pandora's border, NVIDIA again has 2.2 Joule per frame, while the 2.94 and 3.00 Joule for B580 and B570; AMD has trails at 4.29, so the efficiency is minimal.
| Arc B580 | Arc B570 | |
|---|---|---|
| XE kernel | 20 | 18 |
| Render slices | 5 | 5 |
| RT unit | 20 | 18 |
| XMX AI Engine | 160 | 144 |
| Graphic clock | 2670MHz | 2500MHz |
| memory | 12GB | 10GB |
| Memory interface | 192 | 160 |
| Memory bandwidth | 456GB/s | 380GB/s |
| Peak top | 233 | 203 |
| Power of the board of directors | 190W | 150W |
Of course, power efficiency is just one element of a great graphics card, and it is worth mentioning our pure performance results – like we will do in the following page.
Before you start, it's worth highlighting the system we use in most performance tests – this is our standard high-end GPU benchmark. This is based on the fastest gaming CPU, the AMD Ryzen 7 9800x3d, to transfer the burden to the graphics card as much as possible. We also have 32GB of Corsair DDR5-6000 CL30 memory, a high-end Asus Rog Crosshair X870E hero motherboard and a 1000W Corsair PSU.
We will also look at the performance of more realistic matching components – especially low-end CPUs, which are subject to greater effects from Intel’s higher driver overhead – which the driver did on page 8.
That being said, let's start to master pure performance benchmarks.
