Intel Arc B570 overview: a funds GPU that is too good to be true?
Intel’s Arc B580 graphics card impressed us a few months back, due to genuinely respectable efficiency with loads of VRAM at a mainstream value, however we by no means acquired round to reviewing the even cheaper B570 mannequin – till now. Which may not be such a foul factor although, because it’s meant that we might spend some actual time utilizing this GPU because it’s meant for use, get an thought of availability and run some further exams on the driver overhead issues recognized by the tech press post-launch.
We’ll get into that stuff in a second, however for now let’s reply a easy query: what separates this nominally $220 B570 card from the nominally $250 B580? The reply shouldn’t be a lot – and that makes the B570 maybe the extra compelling of the 2 choices.
Particularly, we’re a drop from 20 Xe cores and RT items to 18, XMX AI engines go from 160 to 144 and core clocks drop by round six %. The largest change is to the reminiscence subsystem, which strikes from 12GB of GDDR6 on a 192-bit bus to 10GB on a 160-bit bus, so the B570 solely has 83 % of the bandwidth afforded to the full-fat B580. Energy additionally drops considerably, from a rated 190W to only 150W on the B570.
These energy reductions really feel properly proportional to the cutbacks elsewhere, and testing helps that concept. With out spoiling the outcomes on the next pages an excessive amount of, the B570 achieves round 89 % of the B580’s efficiency whereas drawing 88 % of its energy in video games like Alan Wake 2, with the same 87 % of the efficiency for 88 % of the facility in Senua’s Saga: Hellblade 2.
After all, these outcomes do not exist in a vacuum, and it is instructive to take a look at how the Arc playing cards evaluate to their nearest AMD and Nvidia equivalents in terms of energy effectivity. The Nvidia RTX 4060 beats the B580 in efficiency phrases in Alan Wake 2, for instance, whereas drawing 80 % of the facility. The AMD RX 7600, in the meantime, is the quickest choice at 107 % of the B580’s common frame-rate whereas consuming six % extra energy to take action.
If we have a look at these Alan Wake 2 leads to pure effiency phrases, measured in joules per body, the RTX 4060 is the outright chief at 3.19, adopted by the opposite three playing cards grouped tightly collectively: AMD at 3.98, B580 at 4.03 and B570 at 4.06. That adjustments if we have a look at RT efficiency in Avatar: Frontiers of Pandora, the place Nvidia is once more in entrance at 2.2 joules per body versus 2.94 and three.00 joules for the B580 and B570; AMD trails at 4.29 and is due to this fact the least environment friendly by some margin.
| Arc B580 | Arc B570 | |
|---|---|---|
| Xe Cores | 20 | 18 |
| Render Slices | 5 | 5 |
| RT Models | 20 | 18 |
| XMX AI Engines | 160 | 144 |
| Graphics Clock | 2670MHz | 2500MHz |
| Reminiscence | 12GB | 10GB |
| Reminiscence Interface | 192-bit | 160-bit |
| Reminiscence Bandwidth | 456GB/s | 380GB/s |
| Peak TOPs | 233 | 203 |
| Complete Board Energy | 190W | 150W |
After all, energy effectivity is only one factor of an excellent graphics card, and it is price our pure efficiency leads to larger element – as we’ll do over the next pages.
Earlier than we start, it is price underlining precisely the type of system we’re utilizing for almost all of our efficiency testing – which is our commonplace high-end GPU benchmarking rig. That is primarily based round what continues to be the fastest gaming CPU, the AMD Ryzen 7 9800X3D, to shift the burden to the graphics card as a lot as attainable. We even have 32GB of Corsair DDR5-6000 CL30 reminiscence, a high-end Asus ROG Crosshair X870E Hero motherboard and a 1000W Corsair PSU.
We will even be efficiency on extra realistically matched elements – particularly lower-end CPUs that take a larger efficiency hit from Intel’s notably increased driver overhead – which follows on web page eight.
With all that mentioned, let’s get into the pure efficiency benchmarks to begin off.
