Oculus Quest 2 is the most well liked factor in VR proper now- essentially the most highly effective standalone VR headset you should purchase. However simply how highly effective is it? Can it evaluate to a PlayStation or PC?
Gaming PC and consoles use your essentially-unlimited mains energy and have a tendency to have a robust cooling system involving a number of giant followers. They draw lots of of watts to realize most efficiency.
Quest 2 makes use of the Qualcomm Snapdragon XR2 chipset, which is a variant of the Snapdragon 865 chip utilized in excessive finish smartphones like Samsung’s Galaxy S20 Extremely.
Cellular chips must make wise use of the onboard battery, and there’s a lot much less house for the cooling system. They’re designed for effectivity as a lot as performance- usually drawing just some watts.
Regardless of these limitations, the large funding in R&D on cell chips over the previous decade, pushed by the large smartphone & pill business, means Quest 2’s Snapdragon XR2 holds up surprisingly properly.
The CPU (central processing unit) is the overall computing element. It executes the code and sends rendering directions to the GPU. In video games, the CPU is principally taxed by physics and AI calculations.Headset Node Course of “Gold” Cores “Silver” Cores Cache Oculus Go 14 nm 2x 2.three GHz 2x 1.6 GHz 2 MB L2 Oculus Quest 10 nm 3x 2.three GHz 4x 1.9 GHz three MB L2 Oculus Quest 2 7 nm 3x 1.5 GHz 4x 1.9 GHz 1.eight MB L2

Quest 2’s CPU is clocked considerably decrease than what it’s theoretically able to.
CPUs in cell chips, like Qualcomm’s, really use a special Instruction Set Structure (ISA) to the Intel & AMD CPUs utilized in PCs. Cellular chips use ARM, whereas PC chips use x86. Meaning direct comparability is difficult.
Fortunately, benchmarking instrument GeekBench 5 is particularly designed for such cross-architecture comparisons. We sideloaded the instrument onto Go, Quest 1 and Quest 2 to see how they stack up. We’ve added the rating of the Intel CPU listed on the Half-Life: Alyx Steam retailer web page for comparability:
To benchmark as precisely as attainable, we used ADB instructions to make use of the best CPU clock fee obtainable (Degree four) and disabled Guardian. We used a sideloaded fully clean Oculus House surroundings.
Quest 2’s CPU makes modest positive aspects over its predecessors, however the low clock pace means distinction isn’t fairly as massive because the three technology leap may counsel.
There are after all newer CPUs from each Intel and AMD. Should you’ve bought sufficient cash, you may get a CPU that may make the opposite bars right here too small to fairly evaluate.
The GPU (graphics processing unit) is accountable for rendering pictures and different graphical duties. The GPU is the principle element of a video/graphics card, so the phrases are sometimes used interchangeably.Headset GPU Node Course of ALUs GFLOPS Oculus Go Adreno 530 14 nm 256 ~450 Oculus Quest Adreno 540 10 nm 384 ~560 Oculus Quest 2 Adreno 650 7 nm 1024 ~1250
From the specification sheet alone it’s obvious that Quest 2’s GPU is a major upgrade- rather more so than the CPU. Actually, it’s the primary standalone VR headset to cross the 1 TFLOP mark, bringing it into the identical efficiency territory as the unique Xbox One.
Or put one other means, Oculus Quest 2’s GPU is (on paper at the least) twice as highly effective because the Nintendo Change’s. Each are priced at $299.
Or course, a Change can render at 720p 30FPS and nonetheless produce an appropriate expertise. Quest 2’s default render decision is twice as many pixels per eye, and the minimal FPS for video games is 72. So please don’t count on The Witcher three in cell VR.
However does that efficiency present by way of in precise use? To benchmark GPUs throughout platforms we’re utilizing GFXBench Aztec Ruins. Like GeekBench for CPUs, GFXBench is designed to have in mind structure variations.
Our outcomes counsel Quest 2’s GPU is certainly an infinite improve. The system runs at the next default decision than Quest 1, and may help 90Hz mode with 25% extra frames per second. But some VR builders have already gone additional than this, including new textures, shaders, muddle geometry, and results for Quest 2 house owners.
Nonetheless, evaluating to the graphics playing cards listed on the Half-Life: Alyx Steam retailer web page, Quest 2’s graphical capabilities are loads much less spectacular:
Standalone VR is making big strides in graphical horsepower, but it surely nonetheless has a protracted technique to go to match even 2016’s PC (nevermind 2020’s).
RAM (random entry reminiscence) is the place a pc briefly shops property and information presently in use. It’s considerably sooner than the principle storage.
Extra RAM permits for bigger environments and fewer loading or hitching when transitioning between areas.
Quest 2’s 6GB of RAM could possibly be the important thing to supporting AAA-scale open worlds in future.
Remember that on all methods, some RAM is taken by the working system and background processes.
