Last week, Qualcomm invited me onsite to benchmark their newest Snapdragon 845 SoC and platform. This new Snapdragon 845 was initially unveiled on the firm’s huge occasion in Maui late final 12 months. With the brand new Snapdragon 845 there are various enhancements to the GPU efficiency, with a concentrate on VR and AR purposes.
The new Snapdragon 845 brings a very new era of GPU structure into play whereas nonetheless remaining on the 10nm course of node. I spent a while evaluating the brand new Snapdragon 845’s efficiency towards the main smartphones so to get an concept of how a lot of an enchancment this actually is. Additionally, it can assist you get an concept of what sort of efficiency ranges the brand new Snapdragon 845 VR and AR HMDs may need once they launch this 12 months.
Snapdragon 845 Performance
I ran many assessments, however for the needs of XR, I’m going to only embody GeekBench 4, GFX Bench and AnTuTu. Each of those represents a unique a part of the SoC’s efficiency and AnTutu represents complete system efficiency.
As you’ll be able to see from AnTuTu, the Snapdragon 845 is roughly 30% quicker than the earlier era and the iPhone X. This has lots to do with the truth that AnTuTu provides graphics efficiency a substantial quantity of weight, but additionally CPU and different capabilities together with UX and reminiscence. In reality, the Snapdragon 845 improvement gadget that Qualcomm offered for testing has slower reminiscence than another industrial units and is across the identical kind issue as the opposite units examined relatively than a thick improvement gadget that has extreme cooling. More on cooling later.
For GFX Bench, we’re purely graphics efficiency. The crimson bar represents uncooked GPU efficiency impartial of the show, whereas Manhattan efficiency reveals OpenGL ES 3.0 efficiency primarily based on the put in show on the gadget. Do remember the fact that GPU efficiency is extraordinarily essential for AR and VR and that’s why that is such an necessary benchmark and most theoretical efficiency elevated practically 30% on GFX bench over the Snapdragon 835 and will translate to considerably improved framerates and extra constant latency.
GeekBench 4 is the CPU benchmark that everybody loves to have a look at when evaluating smartphones, as you’ll be able to see right here, the Snapdragon 845 is certainly the quickest among the many Android bunch by a noticeable quantity, however Apple nonetheless takes the cake with their A11 processor within the iPhone X. However, in terms of AR and VR, GPU efficiency remains to be extra necessary than CPU despite the fact that you continue to can’t be a slouch in terms of CPU both.
Snapdragon 845 in XR
In addition to the Snapdragon 845 efficiency, Qualcomm additionally confirmed their newest Snapdragon 845 VR improvement package, which is an replace to the Snapdragon 835 model launched final 12 months for companions to construct from. This new model seems to include the usage of a 3-DoF controller with the opportunity of a 6-DoF presumably coming down the highway. They nonetheless help eye-tracking with the Snapdragon 845 improvement package , but it surely hasn’t been built-in but in software program so we should be ready on that.
In addition to having elevated efficiency of between 20% and 30%, the Snapdragon 845 additionally incorporates a energy discount of about 20%-30% when operating on the identical efficiency because the earlier era. That means you’ll be able to stream movies in 4K 360 at 20%-30% much less energy or get extra battery life out of the identical battery measurement or cut back battery measurement and nonetheless get the identical battery life. That’s why the Snapdragon 845 is such an important chip for XR. I used to be already fairly excited for some Snapdragon 835 units final 12 months, however as soon as I knew how briskly Snapdragon 845 could be, I instantly modified my thoughts and had my eyes set on the Snapdragon 845. I think that some firms additionally had the identical state of mind and that’s why firms like Facebook haven’t explicitly said what SoC is within the Santa Cruz prototype, despite the fact that we all know it’s Qualcomm.
