ARM new product line analysis, the secret is actually all in the naming

ARM has just announced the CPU and GPU architecture, in fact, there are these little secrets.

Previously, we at Three Easy Living just gave you an analysis of the features of ARM’s newly released Cortex-X2, Cortex-A710 and Cortex-A510 new CPU architectures. At that time, we pointed out that the performance progress of the new processor architecture may not be as great as we thought, but after this article was issued, some readers left comments that other media said that this is a new architecture, ARM also adopted a new product naming system for this purpose, so how can the progress is not great?

Emmmm…… have to say, ARM’s naming of this generation of products really bluffed a lot of people. So we’re here today to tell you what’s going on with this new generation of ARM products, and what hidden information is contained in their “new naming system”.

First of all, we need to explain to you one thing, that is, about ARM’s product naming this time. Many friends may see some related reports that ARM is using a new product naming laws, such as 710, 510, 310, etc., but this statement is actually not true.

Why? Because in ARM’s current product sequence, the first number represents the positioning of the product, such as 7 is the high-end, 5 is the mid-range, 3 represents the entry model. The next number represents the generation of the product, for example, “710” actually can not be pronounced as “seven hundred and ten”, but should be “seven – ten”, because The “10” actually refers to the tenth generation, corresponding to the previous generation of products, which is now commonly used Cortex-A78 and Mali-G78.

See here, some of you may have to ask, so where did the 79 run to? This is a good question. In fact, according to ARM’s previously announced product plans, this year should indeed be the debut of the “79” series, while the full shift to 64-bit “710” is supposed to be released next year. But perhaps because the industry’s demand for mobile high-performance computing is very urgent, so ARM has also made such a hand. On the one hand, they released a new pure 64-bit architecture design that was originally scheduled to debut next year, but on the other hand, the “tinkered” 79 series was actually not abandoned, but in a sense, in the form of technology mixed with the 10 generation debut.

Why do we say so? You may want to go back to our previous article on the processor analysis content, you will find two of the doubts. The first is that this time the Cortex-X2 mega-core as well as the Cortex-A510 both support pure 64-bit applications only, but the Cortex-A710 mega-core is compatible with both 32-bit and 64-bit applications; the second is that the Cortex-A510 is a huge performance improvement compared to the Cortex-A55, but the Cortex-A710 is not a significant improvement compared to the Cortex-A78 is not a significant improvement.

What does this mean? It’s simple, because Cortex-X2 and Cortex-A510 are true “10” generation architectures with pure ARMv9 instruction set, released ahead of schedule. The Cortex-A710 also uses the ARMv9 instruction set, but adds an additional support module for 32-bit code. This fully explains the two doubts we raised in the previous article, and also explains the question of where the “A79” goes. It is likely that it was incorporated into the Cortex-A710 design in the form of this 32-bit module.

And because of the existence of the Cortex-A710 compatible with the old instruction set, it also means that for the new machines in 2022, they will still retain a certain degree of compatibility with 32-bit applications, but at the same time, because at this time 32-bit applications can only run on the Cortex-A710 large core, so instead they will cause them to be more power hungry than 64-bit applications (which can run on the Cortex-A510 The ARM action to completely expel 32-bit applications is also considered to be more power-efficient.

But compared to the confusing and more or less fishy CPU lineup, the simultaneous release of the Mali GPu family really deserves some praise this time.

Like the new CPU family, ARM’s new Mali GPUs also skipped 9 generations in naming, and were directly named Mali-G710, Mali-G610, Mali-G510 and Mali-G310 in order of positioning from high to low.

So what are the main improvements in the new GPU lineup of “Generation 10” compared to the previous generation of Mali-G78 and G68? Simply put, there are three main areas.

First, ARM did modify the underlying design of the new GPU. The previous generation of Mali-G78 and others focused too much on 16-bit floating point computing to improve AI performance, but in reality most graphics processing uses 32-bit floating point, so this new architecture first strengthens 32-bit floating point performance, while adding new instructions to specifically improve performance when using the Vulkan interface for games. If you don’t understand this text, you can simply understand that the previous generation of products focus too much on AI computing, while this generation is back to strengthen the performance of the “game”, which is really a very meaningful change.

Secondly, what many friends may not know is that in the past ARM’s Mali-G3x series GPUs have actually been using the ancient architecture on Mali-T6xx to T8xx. This is like many entry-level graphics cards on the PC actually use the same old design from years ago (such as NV’s MX450, which is actually derived from GTX1050), all to minimize costs. And with the new Mali-G310, ARM finally completely abandoned the old architecture and gave the entry-level GPU the latest underlying design. This change directly makes Mali-G310’s single-core texture performance 6 times higher than its predecessor, which shows how “pitiful” the previous old product was.

Lastly, we believe that the most significant change to ARM’s new Mali GPU is that ARM has finally mandated the number of cores for different levels of GPUs, thus eliminating the possibility of chip makers “screwing people over”.

What does this mean? If you think back to some low-end mobile platforms on the market, have you ever seen such GPU configurations as “Mali-G72MP3” or “Mali-G76MP1”? At first glance, such a mobile platform seems to be using the latest and strongest GPU models at the time, but in fact, other platforms Mali-G76 pile more than ten or twenty cores, while it only uses one core, the actual performance is only entry-level level.

On the flip side, there are some manufacturers who buy the low-end and mid-range Mali-G52 licenses in order to save costs, and then pile them up to MP6 in one breath, which ultimately performs better than G72MP3. This seems to be cheaper for consumers, but in fact it also causes consumer confusion and naturally hurts the credibility of ARM’s entire product sequence.

Because of this, on the latest generation of Mali GPUs, ARM directly specifies the relationship between the product name and the number of cores. For example, Mali-G310 is allowed to use only a single core (MP1), Mali-G510 up to six cores (MP6), and ARM also stipulates that when a manufacturer uses less than eight cores (MP8) of Mali-G710 cores in a SoC, it cannot use the name Mali-G710, but must be called Mali-G610, which means that only when the Mali-G710 cores are stacked to greater than or equal to eight cores before they are allowed to be called Mali-G710.

Obviously, so for the entire 10-generation Mali GPU product line, Mali-G710 performance is bound to be stronger than Mali-G510, Mali-G510 performance is bound to be stronger than Mali-G310, as to which manufacturers dare to use Mali-G610 naturally, it is easy to see the problem. Consumers no longer have to worry about their GPU performance pitted, but can also more simply buy a phone with higher gaming performance and play with peace of mind.
