Huawei has introduced their subsidiary HiSilicon’s newest mobile processor in the Kirin 980, which, along with Huawei's claim of the world's first commercial 7nm SoC, is the first SoC to use Arm Cortex A76 CPU cores and Arm’s Mali G76 GPU.
Huawei is aiming squarely at Qualcomm with this announcement, claiming better performance than a Snapdragon 845 during the presentation. One of its primary differences to the current Snapdragon is the composition of the Kirin 980’s eight CPU cores, notable as the usual 'big.LITTLE' Arm CPU core configuration for an octa-core design gives way to a revised organization with three groups, as illustrated by AnandTech here:
Of the four Cortex A76 cores just two are clocked up to maximize performance with certain applications such as gaming (and, likely, benchmarks) at 2.60 GHz, and the other two are used more generally as more efficient performance cores at 1.92 GHz. The remaining four A55 cores operate at 1.80 GHz, and are used for lower-performance tasks. A full breakdown of the CPU core configuration as well as slides from the event are available at AnandTech.
Huawei claims that the improved CPU in the Kirin 980 results in "75 percent more powerful and 58 percent more efficient compared to their previous generation" (the Kirin 970). This claim translates into what Huawei claims to be 37% better performance and 32% greater efficiency than Qualcomm’s Snapdragon 845.
The GPU also gets a much-needed lift this year from Arm's latest GPU, the Mali-G76, which features "new, wider execution engines with double the number of lanes" and "provides dramatic uplifts in both performance and efficiency for complex graphics and Machine Learning (ML) workloads", according to Arm.
Real-world testing with shipping handsets is needed to verify Huawei's performance claims, of course. In fact, the results shown by Huawei at the presentation carry a this disclaimer, sourced from today’s press release:
"The specifications of Kirin 980 does not represent the specifications of the phone using this chip. All data and benchmark results are based on internal testing. Results may vary in different environments."
The upcoming Mate 20 from Huawei will be powered by this new Kirin 980 - and could very well provide results consistent with the full potential of the new chip - and that is set for an official launch on October 16.
The full press release is available after the break.
Introduction and Specifications
Immediately reminiscent of other phablet devices, the Mate 8 from HUAWEI is a characteristically large, thin slab of a smartphone. But under the hood there's quite a departure from the norm, as the SoC powering the device is new to the high-end phone market - no Qualcomm, Samsung, or even MediaTek here.
"The Mate 8 takes the look and feel of the Mate series to a whole new level. Boasting a vivid 6" FHD display, an ultra slim design, a re-designed fingerprint sensor that's faster and more reliable, and a sleek aluminum unibody design, the Mate 8 is sure to impress."
The HiSilicon Kirin 950 powers the Mate 8; an 8-core design comprised of 4x ARM Cortex-A72 cores clocked at up to 2.3 GHz, and 4x ARM Cortex-A53 cores clocked at up to 1.80 GHz. Memory is 3GB for our sample, with 32GB storage; with 4GB RAM and 64GB storage is also available.
The Mate 8 looks every bit a premium device, and the metal and glass construction of the handset feels solid. It also feels rather light (185g) given its size. But how does it perform? This is an especially interesting question given the unusual silicon in the Mate 8, but the Kirin 950's Cortex-A72 is the most powerful ARM design (at least until the Cortex-A73, announced this summer, finds its way into devices).
In this review we'll explore the overall quality of the HUAWEI Mate 8, and go over usage impressions. And, of course, we'll look at some performance benchmarks to see how this Kirin 950 SoC stacks up against recent Snapdragon and Apple SoCs.
