The Adreno 650 increasing this by 50% could either mean we’re seeing three 256-ALU cores, or that there’s now two 512-ALU cores. The Adreno 630 and 640 were both 2-core GPUs with each respectively 256 and 384 ALUs per core based on the measured throughput. Qualcomm's " Mobile GPU approaches to power High-Performance Graphics 2019Įarlier last summer Qualcomm did detail some titbits of its architecture, describing the ALUs execution units as being separate MUL+ADD units per lane, and also showcased some first-party performance metrics of the Adreno 640 GPU. It’s to be noted that the company did say we’ll be see higher improvements in some workloads, for example higher complexity tests such as Aztec might see a higher percentage. Qualcomm’s improvement claims for this generation come down to an aggregate of 25% over a variety of industry benchmarks and real workloads. It’s actually a bit unusual for Qualcomm to remain in the 600-series this year and the company had never before stretched out an architecture over three generations like this. On the GPU side of things, we’re seeing Qualcomm make evolutionary changes to the new IP block. The Adreno 650 GPU: Similar Architecture, Wider Microarchticture While the performance benefits here are welcome, Qualcomm explains that the main reason for the change was increased power efficiency, reducing more expensive DRAM memory accesses in light workloads, which makes a lot of sense. One aspect that Qualcomm did finally improve on is the 元 cache of the CPU cluster, which has now been increased from 2MB to 4MB.
#Adreno 530 teraflops update#
We’re very much overdue a large microarchitectural update from Arm as the yearly small efficiency core updates from Apple now put the Android SoCs to shame in regards to performance and efficiency. The Cortex-A55 cores remain practically the same, which to be honest are getting a bit long in the tooth as they’ve essentially not changed in 3 generations now.

In absolute terms at maximum performance, the new Snapdragon 865 big CPUs use more power to achieve their higher performance, meaning efficiency at peak perf is flat. Qualcomm claims a 25% power efficiency gain for the new SoCs, but this is an ISO-performance comparison against the previous generation (At equal performance to the S855, the S865 uses 25% less energy/power). As we had expected, we’re not seeing any clock improvements this year, and the CPU frequencies remain flat, reaching an identical 2.84GHz for the “Prime” core and 2.4GHz for the “Gold” cores. Still, the new CPU microarchitecture is said to be able to offer a 25% performance uplift this year, all of it which is essentially due to IPC improvements of the new design. Qualcomm saw that the return on time investment with Arm to customise previous generations didn't result in as high returns as they would have hoped, and for the Snapdragon 865 they simply opted to use the default configuration Cortex-A77 as offered by Arm.

#Adreno 530 teraflops license#
A larger change in strategy this year is that while Qualcomm still uses the “Built-on-Cortex-technology” license to be able to customize some parts of the interface IP of the CPUs (And be able to brand it as the Kryo 585 parts), they’ve abandoned customisations on the CPU core itself. The big difference of course, that instead of using Cortex-A76 based cores in the S855, the new chipset is using Arm’s newest Cortex-A77 cores. We find the same 1+3+4 CPU configuration as found on the Snapdragon 855, using the same 2.84GHz, 2.4GHz and 1.8GHz clock frequencies, and the same 512KB, 256KB and 128KB L2 cache configurations. On the CPU side, the Snapdragon 865’s improvements over the Snapdragon 855 are very straightforward in terms of specifications: SoCġx Kryo 485 Gold (A76 2.84GHz 1x512KB pL2ģx Kryo 485 Gold (A76 2.42GHz 3x256KB pL2Ĥx Kryo 485 Silver (A55 1.80GHz 4x128KB pL2 Cortex-A77 Cores, LPDDR5, Adreno 650 GPU No More CPU Customisations For Now: Cortex-A77 Used
