Seems like it's reconfigurability is limited to the functional unit interconnect. Doesn't seem like a full blown FPGA.

Sincerely ask how many TMUs in mali adreno and tegra series?
Mali T604 and Adreno320 each have 4 TMUs; no idea about Tegra4 yet.

thanks very much,may I ask what we have known about tegra4?

The only "almost certain" information we have is that the Tegra 4 (Wayne) GPU will use unified shaders.
As for rumours, some say it'll use Kepler ALUs, others say it'll be a quad-core Cortex A15 with a fifth Cortex A15 acting as "ninja core" (like Tegra 3) instead of going big.LITTLE and a dual-channel memory controller.
Other rumours say they'll also introduce a Tegra 3-ish SoC shrinked to 28nm with integrated baseband (Grey) in the market for mid-range smartphones.
It's also possible it'll be a higher-clocked dual-core Cortex A9 + ninja core instead of the current quad-core, to give more room to the integrated baseband.
I guess this SoC would compete with the MT6588 and MSM8x26, both with lower-clocked quad-core Cortex A7 and integrated baseband.
I'd love to be pleasantly surprised, but my gut feeling tells me rather a 4*SIMD16 config (with a single TMU/cluster) just like the others and roughly above OGL_ES3.0 and yes chances are high that I'm completely wrong but I'm rather pleasantly surprised in a contrary case then dissapointed if I'm right.
I expect the next Tegra to pleasantly surprise for graphics and compare more favorably to the competition, PowerVR notwithstanding, than last time.
Part of my projection for a better showing for nVidia actually has to do with a relative weakening from Qualcomm. While Qualcomm had inherited a decent architecture for the Adreno 2xx series, I worried their team, now divorced from a graphics specialist like ATi/AMD, wouldn't have the focus to keep pace with new architectures from IP houses and specialists like IMG and ARM.
As benchmarks are presently indicating, the new Qualcomm SoCs are bumping up against some thermal walls in attempting to push to a competitive level of performance.

Isn't that a wee bit unfair since we haven't seen an Exynos5250 in a smartphone yet?
Not only that but I personally consider S4 a competing part to the 5250. So far we've seen 5250's only in tablets and no smartphone and I'm not so sure all things would be "that" ideal if they'd be in smartphones today.

4x4 big.LITTLE Exynos confirmed/announced: http://www.theverge.com/2013/1/9/3855478/samsung-announces-8-core-exynos-5-octa-mobile-processor
I'd like to think Samsung wouldn't be blowing smoke about GPU claims with a device that uses the same GPU as the last one they released but we all know how they work
Have any other details been announced? The old rumors were 28nm, 1.8GHz max frequency for the A15s, and 1.2GHz max frequency for the A7s.

I'm asking because ARM itself places T624 within 2013.

Exactly, where are the marchitecture slides ?? Checked Samsung semi's site, but over they can only count up to 4.
Still it's interesting to see how the ARMs (arms) race in mobile is unfolding. Where does it end ? Next year Cortex A50 CPUs in 22nm or will 2014 be a "tock" year ?

Samsung usually never pulled figues out of their ass in this regard and the 4412 marketing figures from last year were pretty accurate to reality, if so, 70% savings is quite remarkable.
Unless I'm missing something there's no T658 anymore mentioned on ARM's homesite.

It was on the roadmaps for quite some time, but they apparently scrapped it with the T6x4 revisions. The question is if it got scrapped for this chip too or not. It can be anything from the T6xx family. A T624 would make sense.
