In keeping with Intel’s oneAPI and the possibility of actually being able to enable this option in games, I have another classic for you today. Whether Intel decides to handle the whole thing as open or closed source, however, will probably also depend on how Intel will continue with the graphics card division at all. I don’t want to quote Jon Peddie again, but there are certainly more important construction sites than the oneAPI at the moment. Of course, this option could also be seen as a medicine against the current hiccups of the Arc graphics cards, which closes the circle again.
Original article
And every year the groundhog greets… Due to the recurring questions in the forum and direct inquiries from interested readers, we want to go a bit further this year and also look into the theory a bit besides the usual SLI and Crossfire benchmarks, because frame rates alone don’t say too much about the real output quality. Micro-stutters are just as much an issue as the question of the actual scaling over 2, 3 or 4 GPUs. Where is the benefit, when do you get a real added value or do you end up cheating yourself with high, but in practice rather useless frame rates? Where do the money and power crunches begin and where might you still find a bargain?
What’s different this time?
The problem with measuring scaling over more than 2 GPUs in the mid-range cards is that there is only a single port for a bridge per card, while the cards with 2 ports are exclusively in the high-end. Unfortunately, multi-GPU solutions with more than two cards are not really in our readers’ buying range in the high-end sector. The new Powercolor Radeon HD 6870 X2, which combines 2 of these smaller mid-range GPUs on one board, even allows us to quad-crossfire with mid-range chips!
Thus, it is also possible for the first time to test a pure mid-range card like the Radeon HD 6870 for currently about 140 Euros as a Crossfire with 2 cards in comparison to the dual-GPU card Radeon HD 6870 X2, to compare this afterwards with the performance from 3 GPUs (HD 6870 X2 + HD 6870) and in the end even to measure it as a Quad-Crossfire and to compare all this with SLI and Crossfire of many current cards up to the GTX 590 in extensive benchmarks. We want to compare the power delivery, check the relevance of the micro jerks and finally judge the performance and the price-performance ratio. Are we perhaps in for a surprise here? Nothing can be ruled out, so just keep reading!
