Freescale iMX6 Discussion

@darkblu:
yes certainly possible.


@Exophase:
i.MX6 is also available in industrial/automotive temp. grades - that's not the case for most other smartphone SoCs.

The memory Interface is 64 Bit DDR3-1066 / dual 32 Bit LPDDR2... Tegra 2+3 have 32 Bit LPDDR2 only (so speed should be like DDR2-800).


Here's a recent Video of it driving 4 Displays (2x 1080p + 2x XGA) at the same time:

First GC1000 GLBenchmark2.1 results: http://www.glbenchmark.com/phonedetails.jsp?D=Marvell+Armada+1000+88DE3010+Berlin&benchmark=glpro21

MSAA still takes a significant drop. Is that product brief new or have I missed it in the past? http://www.vivantecorp.com/Product_Brief.pdf

At least according to that one it's clear now how the variants exactly scale in core amounts. Frequency of that GC1000 is unknown of course, but if it should be for the comparable region in the iMX6/GC2000 it still doesn't sound like a iPad2 killer.

Unless of course they're also having driver troubles.
 
It seems to have twice the performance of the previous GC800.

According to the pdf that Ailuros pointed out, the GC1000 seems to be a dual-core GC800, with GC2000 being a quad GC800 and GC4000 being eight GC800 cores.

Looking at the synthetic scores and assuming a linear scaling with core amount, the GC2000 should be right next to Exynos 4210 in pixel shader speed and quite a bit better in vertex shader speed.. so the GPU to battle a SGX543MP2 should be the GC4000.

At 12.9mm^2, how does the GC4000 compare to the SGX543MP2 in size?

Apple's A5 doesn't help for such a comparison since it's a huge SoC die anyway. It's over 120mm2 big under Samsung 45nm and Apple obviously didn't care a bit about die area. Roughly 1/4th of the A5 are the 2 A9 CPUs@1 GHz and roughly 1/4th the block for the MP2 GPU block. In that regard you can't just claim that the MP2 there is over 30mm2@45nm, disregarding how generous Apple was with die area. Else the CPU block in A5 is also roughly over 30mm2, while Tegra2 as an entire SoC weighs 49mm2@40nm.

I don't have much hope to get any details for the Renesas SoC with the SGX543MP2, but it could probably help.

I think that's way too pessimistic. I'd guess that JohnH's estimate of the GC2000 probably ending in the =/>70% range of a SGX543MP2 shouldn't be too far from reality. That would give roughly twice the performance of the GC1000 which sounds reasonable. If true the GC4000 (that's 8 cores and since the product brief smells like single TMU/core it could mean 8 TMUs), I'd rather place that one against a SGX54xMP4, with the latter still being a notch ahead.

Their die area figures (if true) remain impressive.
