MediaTek to launch 2GHz octa-core SoC, the MT6592

0. phoneArena 02 Jul 2013, 09:21 posted on

Until recently, MediaTek was known primarily for its low-cost, low-performance SoCs used in cheap, white-box smartphones. However, things have changed since then. Take the Acer Liquid E2, for example – it is powered by one of the company's latest quad-core chips and its performance is quite decent for its class. Yet MediaTek has even better silicon in stock...

Wow this is very interesting!

Cortex-A7 ? Why not Cortex-A15 ?

I'm guessing it would be too powerful with 8 A15s, to the point where it really becomes insignificant that a higher price would not justify.

Cortex A15 is simply not power-efficient enough to be used alone in a smartphone, and my guess is that efficiency was a prime concern for MediaTek, but if used in a big.LITTLE configuration (four A7 cores and four A15), it'd make a lot of sense. Why not use big.LITTLE is an interesting question, though.

Exactly Mr.Victor
For me i think quad A15 will be better than octa A7 , why ?
Because most apps are written to support usually 4 cores

1. According to ARM's website, it's not possible to use more than 4 A7 cores on one SoC.
2. Even if they get all 8 cores to work they will work on the same voltage plane. Which means that if you stress even one single core to 100% the entire herd of cores will go to 100% even though they aren't being used.
3. It will be just like AMD's Bulldozer. They will be excellent at heavily threaded tasks, but in web browsing, games, etc. they will be poor performers.
4. Cortex A7s aren't designed for such high clock speeds which means power consumption will be high.
5. Cortex A12 would have been a much better choice.
6. I think they will use 2 quad core clusters just like Samsung's Octa. One cluster operates at 1.2 to 2 GHz while the other cluster operates upto 1.2 GHz.

1. Actually it is possible to use more than 4 cores in one SoC. But they will be put in different clusters.
2. This means the two clusters will operate on independent voltage planes which will sort of mitigate the problem.

mediatek is all about the power efficiency,so that's why they use 8 A7 cores and not the BIG.little architecture

A7 has best per watt performance...that's why MT ditched A15...with 8 cores...apps optimized to get benefit of multi-core cpu...will get huge benefit from it.

Performance isn't determined by just whether a processor is OoO or IO type!

A7 does, like...

-Integrated L2 Cache

-Lower L2 Latency (10 Cycles)

-Improved OS Support for L2 Maintenance, due to simplified software control

-Designed with a lower power approach, up to 5x more efficient than Cortex A8

-Improved branch prediction

-Improved memory performance

-64b Load Store path, improves integer and NEON performance

-128 AMBA 4 buses improve bandwidth

-Increased TLB size (256 entry, up from 128 entry for Cortex A9 and A5)

-Increased performance for large workloads like web browsing

-Seamlessly compatible with Cortex A15 (big.LITTLE)

Add all of those up and they easily start making up for where it would otherwise be weaker.

Probably because 8a7 cores are still more efficient than the a7 a15 big little configuration. But Idk

Some say it scores over 30,000 antutu points ....all we know is ..its called Mediatek

Well well.. I actually proposed an 8 core, high clocked, A7-based chip year ago!

Still not going to be as strong as the current quad core A15 processors. Perhaps a bit more energy efficient.

I don´t really find it a good idea. The single thread performance is not going to be even near the current A15 cores.
Probably another marketing stunt from Mediatek just to add the word Octa to the list after adding the Quad one.

Why? Samsung has had problems producing there octa, and And tech posted a article a while ago about how it wasn't has effective at saving power has it should be. Honestly, it seems ARM needs to fix problems in the designs of the chip (has Samsung only leases the ARM designs).

But this is an actual 8 core CPU, not a double quad core.
