The RTX 3090 is the fastest GPU on the market right now - until Nvidia finally delivers its delayed RTX 3090 Ti - and Apple claims the M1 Ultra can beat a single RTX 3090 while using 200 watts less of power.Īpple made similar claims about its M1 Max beating the RTX 3080 last year, but real-world results were mixed. Apple claims its M1 Ultra can beat the RTX 3090 in certain tasks. Games that natively support SLI will offer performance benefits, while most won’t offer any uplift and some will even see a performance drop. Combining two RTX 3090s together for productivity or gaming rigs has hugely mixed results, though. Nvidia has practically killed off multi-GPU support with its RTX 30-series, with only the RTX 3090 offering NVLink support.

That should mean apps and games don’t have to do anything special to utilize the power of the M1 Ultra, whereas games have had to natively support Nvidia’s SLI implementation on Windows in the past to see any performance improvements. That’s a huge bandwidth jump over what Nvidia offers with NVLink for SLI or AMD with Infinity Fabric, which are used as high-speed links between GPUs.Īpple’s high-speed link means the two separate M1 Max GPUs will be shown as a single GPU in macOS, allowing apps to easily tap into the combined power. Apple’s UltraFusion tech supports an impressive 2.5TB/s of bandwidth between the two M1 Max chips. Nvidia and AMD have built similar solutions for combining two GPUs in the past, but as AnandTech points out, it looks like Apple has solved the holy grail of multi-GPU design here. Apple is ahead of the pack with a chip that fuses together two separate GPUs. Apple rivals like Intel, Samsung, and Qualcomm are in the early stages of working together on a new standard that could let companies build processors out of Lego-like chiplets. The chip industry has been turning to chiplets to design processors for years, with AMD’s Zen 2 and Zen 3-based Ryzen chips leading the pack for modern chiplet designs and until recently, performance. The result is an M1 Ultra chip that has double the CPU cores, double the memory, double the memory bandwidth, and most importantly, double the GPU cores.Īpple calls this combination UltraFusion, and it’s effectively Apple’s own 2.5D chip packaging implementation. The M1 Max has a secret high-speed interface that allows Apple to combine two chips into one. But how does Apple think it can beat an RTX 3090? It turns out, last year’s M1 Max has some secret sauce inside.Īpple’s new M1 Ultra is a surprising combination of two M1 Max dies, fused together to create a single powerful chip. Apple claims it will rival Nvidia’s giant RTX 3090 graphics card, the fastest GPU on the market right now.

Apple’s M1 Pro and M1 Max chips were a GPU-shaped warning to Nvidia and AMD last year, and now Apple has cranked up the heat with its new M1 Ultra.
