Arm v9 Here comes the new product of Architecture .

This is the Arm last year 3 A brand new product will be released in January v9 framework 、5 The first generation was released in January based on v9 The second update after product architecture .

This time, , A total of Two new CPU, Full turn 64 position That kind of , as well as Three new GPU, One of them supports... For the first time Hardware light chasing .

No accident , The fastest At the end of this year or early next year , These products can be used by Qualcomm 、 The latest processors of Samsung and MediaTek have been installed , For example, Xiaolong 8 G2～

that , How much has their performance and power consumption improved ？

Let's see... One by one .

Second generation v9 framework CPU Full turn 64 position

First look CPU.

Arm The first new product released this year CPU by Cortex-X3.

Cortex-X3 As a super core , Key performance improvements ：

And the last generation running on the latest Android flagship Cortex-X2 comparison , Promoted 22%;

And the latest mainstream notebook processor （Intel Core i7 1260p 28w, Instead of Cortex-X1 or X2） comparison , Performance is expected to improve 34%.

Besides , With the same process Cortex-X2 comparison ,Cortex-X3 Of IPC Improved 11%.

Specific indicators ,Cortex-X3 The decoder instructions per cycle from 5 Upgrade to 6 individual , Out of order execution window from 288 Upgrade to 320 individual , Integers ALU Unit from 4 Upgrade to 6 individual ,L2 The cache capacity also increases from 512KB Promoted to 1MB.

Power consumption , From the table below ,Cortex-X3 In most cases than Cortex-X2 Less consumption , But as performance climbs ,Cortex-X3 It certainly doesn't look like “ Fuel efficient lights ”.

Section 2 NEW CPU by Cortex-A715, What this midcore pays attention to is the balance between performance and power consumption .

As Cortex-A710 Successor , It has the same power level and manufacturing process , Power savings 20%, Performance only improved 5%, Than before Cortex-A710 The promotion is much less （Cortex-A710 comparison Cortex-A78 Up 10%）.

however ,Arm Express , This level can also Worth 2020 The heavyweight product of Cortex-X1 了 .

This bodes well for mid tier processor manufacturers , It can improve performance without increasing power consumption .

It is important to mention that ,Cortex-A715 and Cortex-X3 equally , Have given up aarch32 Instruction set , Only support 64 Yes. .

In addition to these two new CPU,Arm This time, we will also review the Cortex-A510 The small core has made a little update , The power consumption is reduced 5%, Most support 12 Nuclear architecture , And the only support 32 Bit compatible CPU.

in addition , This generation of Cortex The processor is for smart phones 、 Tablet, notebook and other platforms , according to Arm said , The new large and small core scheduling architecture can do at most 8+4+0, That is to say 12 nucleus .

GPU Support hardware optical tracing for the first time

Let's look at the new GPU.

The first one is brand new Immortalis-G715（Immortalis Yes “ immortal ” It means ）.

Its biggest feature is that it supports hardware optical tracing on the mobile phone for the first time .

Arm call , This kind of GPU The core area of the shader used for light tracing on the 4%, Compared with light tracing based on software acceleration , Performance improved 300%.

Compared to the previous generation Mali-G710,Immortalis-G715 Performance improvement 15%, Energy saving 15%.

Besides , Its performance in machine learning has also been improved in two aspects , Performance on tasks such as computational enhancement and image enhancement has also improved .

There are two new models left GPU Respectively Mali-G715 and Mali-G615.

Mali-G715 For medium and high-end products , It's essentially a Immortalis-G715, But there is no light chasing , Only 7-9 Shader cores （Immortalis-G715 Yes 10-16 individual ）.

Mali-G615 The number of shader cores continues to decrease , by 1-6 individual , But it still provides the advantages of variable coloring rate technology, performance and power consumption .

On the whole ,Arm The products released this year are not as heavy as when the architecture was replaced last year , but Arm Full turn 64 The determination of the bit instruction set has been formed .

Many netizens said , A bit disappointed ,Arm The gap with apple is getting bigger and bigger .

Others say ：“Cortex-A710 after ,Arm Don't believe anything you say ”.

What do you think ？
