Yes, I believe so. It was pegging multiple cores.

Was this a fully parallel build (using all cores)?

geeB | karma 122 | avg karma 2.0 · | 2022-01-21 05:23:28

No, 1 performance + 4 efficiency cores. It feels like just adding up the count is a bit of a cheat though.

That's correct, I meant the many cores to allude to many processes.

thebruce87m | karma 1640 | avg karma 1.48 · | 2023-10-10 04:17:03

2 cores?

lambda | karma 10355 | avg karma 5.27 · | 2023-08-29 20:24:38

Yes it is. They have four 16 thread pipelines, and two single thread pipelines per core. 4*16=64 and 64+2=66

Was that a full parallel build (using all available cores)?

Because that's what counts for me, as a developer.

I would assume so - it's a 3.7gz quad core and a 3.5ghz hex core

im3w1l | karma 8737 | avg karma 1.51 · | 2016-04-21 04:37:48

Even more cores?

icosahedron | karma 61 | avg karma 2.03 · | 2021-10-20 14:52:28

I thought I remembered that in the presentation they had souped up the individual cores too. Must be I'm misremembering.

Igglyboo | karma 1810 | avg karma 2.05 · | 2014-10-28 14:24:17+00:00

Yes but they said 13x speedup not 13x more processors/cores. Probably just a non-technical writeup tbh.

No, the went multicore because 5 GHz is the physical limit for modern semiconductor processes. And IPC is also hitting its limits.

snek_case | karma 1555 | avg karma 4.02 · | 2021-11-02 22:59:58

You're right this is a dual core, with two way hyperthreading, so 4 logical cores.

blinkingled | karma 6610 | avg karma 3.73 · | 2020-06-10 14:55:07+00:00

What I quoted does clarify (although in a convoluted way) that it is multi-core.

GTP | karma 1552 | avg karma 2.2 · | 2015-07-09 17:13:24+00:00

Wow, that's interesting! Do you know if somebody tried to enable one of this "extra cores"?

tigershark | karma 2132 | avg karma 1.4 · | 2018-09-13 07:38:14+00:00

No, A12 can use all the cores at the same time, it is different from a traditional big.little. At least this is what they said during the event.

shmerl | karma 12092 | avg karma 1.37 · | 2023-04-23 14:15:44

Yeah, the point is about 16 core one.

satvikpendem | karma 10472 | avg karma 2.45 · | 2023-10-19 11:51:10

Looks like you're right, likely C cores based on what I've seen as well.

granitepail | karma 138 | avg karma 2.65 · | 2011-09-13 17:06:25+00:00

Where did you read that? The article would seem to imply it was an eight-core chip they were working with.

andy_ppp | karma 10079 | avg karma 2.53 · | 2023-02-07 07:56:17

This probably sold a lot of extra CPUs.
