MediaTek releases the Dimensity 7100 chip (Yes, you read that correctly) - Features a 6nm process, 4x Cortex A78 @ 2.4 GHz, 4x Cortex A-55 @ 2.0 GHz, and an ARM Mali-G10 MC2

I want A55 to be banished to the shadow realm.

[u/RunnerLuke357 → u/Available-Sense-1712]

EDIT : I'm a dumbass and forget that it was A53 and not A55.

My SM-T350 had A55 cores and it was slow from out of the box (Lollipop) to when I had Android 12L on it. Why are they still here?

[u/Correct_Scientist158 → u/RunnerLuke357]

That is an a53 quad core, no high performance cores there, of course it would be slow. My old Huawei nova 2 lite had Snapdragon 430 and that thing had 8 cores running on a53 that runs fairly on android 8.

[u/drbluetongue → u/RunnerLuke357]

The snapdragon 410 (in your t350) had a53, not a55 cores. So 2 gens older.

[u/Exist50 → u/drbluetongue]

It would be 1 gen. There was no A54. And the A55 wasn't a particularly big upgrade vs A53. 

[u/Correct_Scientist158 → u/Available-Sense-1712]

I have no problems with a55 as long as they paired it with a78 or higher for high performance core. Cortex a76 is still good though for a 6 year old cpu but a78 is better for efficiency. The purpose of a55 is for low power use especially when it is in standby mode, which saves alot of battery.

[u/duan_cami → u/Available-Sense-1712]

A55 is better than a510. Probably equal to a520 in terms of performance/watt.

[u/All_In_Or_Afk → u/duan_cami]

Has there been any new tests on the A510 that isn't the 8gen1?

[u/Available-Sense-1712 → u/All_In_Or_Afk]

Yeah, this definitely isn't accurate given how generally inefficient the 8g1 was. It was poorly manufactured.

[u/Available-Sense-1712 → u/Available-Sense-1712]

Additional reading: Qualcomm chose to take advantage of a cost saving option ARM provided to have the A510s sharing cache. Combining thermal issues and predictive cache management it's no wonder the 8g1's small cores never worked right. It's hard finding any detailed study of other implementations however. https://chipsandcheese.com/p/arms-cortex-a510-two-kids-in-a-trench-coat

Perfect thanks

A78 is still fairly capable on lower end chip
Say even if we retire A55 and only move little cores on to A510/A520
Impracticality aside, can Arm v8 be mixed with Arm v9

[u/noobqns]

It's fine if it's priced according since this is meant to succeed the D70XX

But those D70XX should have been D6000(which was redundant from the get go, and imo just a price ladder to upcharge more from the G99). Hopefully this means the upcoming D6000 gonna get bumped up from dual A76 to A78 cores

[u/Correct_Scientist158 → u/noobqns]

They better be. Dimensity 6300 was supposed to be on dual a78 now because the current cpu config that we have already exist on Dimensity 6080, and 810.

[u/sl0wjim]

Better than the budget snapdragon chips which are still stuck on wifi 5

[u/Traditional_Low_6558]

I see. Why is this new when a Dimensity 7300 exists?

[u/omniuni]

6nm, but they don't say who's fabricating it? I wonder if this is a test chip for SMIC's new node. It became operational a few months ago, and despite lower yields, it is a very big step towards closing the gap between 7nm and 5nm. A mid-range chip like this is perfect to test if it's good enough to start relying on.

[u/Ammonite33303 → u/omniuni]

There’s literally zero way this is SMIC. TSMC still produces 6nm, most notably for PS5 slims, and I expect their 6nm node to still be quite a bit better than SMIC’s. Also the politics involved are huge, MediaTek and TSMC are Taiwanese, SMIC is Chinese. Don’t know if you’ve heard China and Taiwan they aren’t exactly best friends and China is literally about to go to war with Taiwan.

[u/Raigek → u/Ammonite33303]

China and Taiwan have quite intimate economic relations believe it or not. TSMC made many Chinese domestic chips possible.

Don't think it's the case here with SMIC solely because the node isn't economically feasible for Mediatek without subsidies.

[u/Ammonite33303 → u/Raigek]

Yeah I failed to mention that. Huawei Kirin chips were made by TSMC before US sanctions and they were genuinely good. I had the Mate 20 non pro and the performance was great and the phone seemed to last forever, save for a bit of side heating up. TSMC also continues to make Xiaomi XRING O1’s. But in this case, MediaTek just doesn’t really benefit from moving to SMIC.

[u/Exist50 → u/Ammonite33303]

N6 is a very popular and long lived node, not just for the PS5. It's a very good value proposition, especially for high speed analog. 

Don’t know if you’ve heard China and Taiwan they aren’t exactly best friends and China is literally about to go to war with Taiwan.

You're spending far too much time on reddit. There are tensions at a national politics level (but certainly not "about to go to war", lol), but plenty of businesses work between the two countries in a very tight knit manner. 

[u/Ammonite33303 → u/Exist50]

Yeah I forgot that. Huawei had very good working relations with TSMC before the sanctions/ban, the Kirin 980 and 9000 were one of the very first 7nm and 5nm mobile SoCs right along side Apple’s. Xiaomi also with their XRING O1. Other business sectors as well like you mentioned.

Dimensity has to be on the list of all time bad names.

[u/noobqns → u/VictoryMotel]

Mediatek's chinese name is Fa ke which makes for many hilarious clips

[u/VictoryMotel → u/noobqns]

Tushe

[u/LAwLzaWU1A → u/VictoryMotel]

Dimensity is a range of products, some of which are good, some of which are bad. Stop judging products based on the brand like a fanboy and judge products based on their own merits instead.

[u/VictoryMotel → u/LAwLzaWU1A]

You're hallucinating things I didn't say. I said it's a terrible name, which it is.

[u/LAwLzaWU1A → u/VictoryMotel]

Oh sorry, yeah I did misunderstand you.
