ARM introduces Cortex A-73 chip and Mali-G71 graphics chip; higher performance, energy efficient

ARM introduces Cortex A-73 chip and Mali-G71 graphics chip; higher performance, energy efficient
With Android's Daydream VR platform coming in Android N, we should see some new handsets with built-in VR capabilities launched later this year; manufacturers like Samsung, HTC, LG, Xiaomi Huawei, ZTE, Asus and Alcatel are said to be prepping VR focused handsets with some to be released as early as year's end. ARM also sees the future and the Cortex-A73 chip and Mali-G71 graphics chip were both introduced Monday at Computex 2016. Both are coming next year with specs that support VR. While the new chips both are more powerful than their respective predecessors, the pair are easier on a smartphone battery.

Thus far, MediaTek, Huawei's HiSilicon, Marvell and seven others have licensed the new chips from ARM, and have started testing them. Most likely, we wont find the Cortex-A73 and Mali-G71 inside commercially available devices until sometime early next year.
'
The Cortex-A73 is 30% faster than the A72, and is built using the 10nm process using FinFET. This allows the chip to measure less than .65 square mm. The Mali-G71 will support 4K resolution displays with a refresh rate of 120Hz. That is 33% above the minimum 90Hz refresh rate needed for VR. That means that the graphics chip helps the screen refresh 120 frames each second.

The Mali-G71 is 50% faster while at the same time it is 20% more power efficient than the Mali-T880. And with a latency of 4ms, users won't have to worry about a lag. There is also 32 shader cores, twice the amount used on the Mali-T880. This should help those using a phone with the GPU see more accurate and sharper images.

The Cortex-A73 is 30% more powerful than the A72, but also delivers power efficiencies

Read the Anandtech Article. Great stuff, but I'm still waiting for a worthy A53/little core successor

So am I, but they seem to be investing more into power cores instead of efficiency ones. That's why I'm hype over the SD 625. Pair an efficient multicore CPU with an efficient yet powerful enough GPU. HD screens would love this SoC. I can't wait to pick and choose over which phone I want that has it...Moto Z Play, Galaxy C7, HTC one A10(?), or the Zenfone 3 "libra"

ARM are still investing heavy in efficiency cores Here's their cores from ARMv7 to ARMv8 A15->A57->A72 A17->A73 A9->A53 A7->A35 The A73 succeed the A17 But the A73 is still better than the A72 Hence the name and why it will replace the A72 until its true successor is here

I thought the A53 was the successor of A7.

I can see ARM making it tougher for Qualcomm with every time passin by. I am really excited to see S8 Exynos version. Mali G71 looks greak for VR. G71 MP16 would be great for standalone VRs as it consumes only 4W.

VR could actually go for a weak CPU+ strong GPU config. It would also make more sense because multitask won't be the issue here but the visual effect and performance.

It looks like ARM is claiming the MP32 is for standalone VRhttps://community.arm.com/servlet/JiveServlet/showImage/38-6238-79473/4.jpg Edit: Oh oops, actually the various devices below aren't actually in any particular order, my bad It does say: "The scalability of Mali-G71 means superior graphics performance is available across a wider than ever range of devices from DTVs through high end smartphones right up to cutting edge VR headsets, either mobile-based or standalone."https://community.arm.com/groups/arm-mali-graphics/blog/2016/05/30/mali-g71-arms-most-powerful-scalable-and-efficient-gpu-to-date

I can see some ppl not knowing what they talk about. Qualcomm will just lisence the design and custom it to make it even better like they did every single time they used ARM design. For the rest you might be right or not we will see.

Not every single time, 810 was not custom designed and it was s**t, I was better with the 805

Good for ARM and android vendors. But Apple's A-series SoC is still regarded as the Best mobile SoC in the industry in terms of both power and efficiency by the industry veterans. With upcoming 16nm finfet+ fan-out process Apple will increase their SoC's lead in power and efficiency.

Yes if you're talking about that qHD and 360 pixel per inch display of course its efficient compare to those device running on QHD with 500 above pixel per inch count display devices. Lol

Did the SD820 just fly over your head? Similar single core CPU performance, double the number of cores and superior GPU performance in the same thermal envelope? Exynos 8890 tearing up most benchmarks alongside it?

Apple use arm as reference cores.

Sorry Kumar but Apple A serie soc are in fact weaker than latest gen android flagship grade soc. But ios is so light thats its seem faster. Someone really need to take both soc and benchmark them on identical OS so you guys can see it. I remember a test done a few year back for iphone 5 SOC vs Samsung soc both running a linux OS for ARM chipset.. the exynos of samsung had like twice the horse power.. Its all question of what you run. Can have a 2000 horse power mining truck ( the big one ) its will still be slower than a 200 hp honda civic right?

Calling it now: Mediatek and Huawei to use only 4 Shader Cores.

Why not Mali-T1000 so it can reference Terminator? lol

90Hz is not the minimum needed for VR, which is 60Hz as used on Gear VR, Cardboard and soon Daydream. 90Hz is better of course and more recommended but not sure if mobile VR can handle this already, as also the graphics have to be rendered at that speed and have already problems at 60fps.

Yes if you run 60 fps on a 90Hz screen you will have tearing..

ARM focused on sustained performance in A73 core. Last night reading anandtech article, I was skeptical about reducing issue width from 3 to 2. But then I further read about how ARM has improved IPC. Overall it's good step from ARM, a narrow scalable (frequency) core.

We will see A73 within this year at Kirin 960, but at 16nm.
