the beginning of the end for ARM? Galaxy Tab 3 uses atom

[ChronoReverse]

Although ARMv7 is a strict superset of ARMv6 which is a superset of ARMv5, I'd wager that since NDS software is much closer to the metal it's not as easy. Plus there's more than just the CPU cores to emulate.

With that said, the interpreted engine is faster than the current dynarec engine because of the penalty. Emulating the rest of the DS is probably better served with high level emulation.


Nonetheless, the point is that it's one of the weakpoints of the ARM architecture. It's not a perfect architecture like some seem to think.

It's a weak point of any architecture with split data and instruction caches. Which is most of them besides Intel. I think even AMD's architectures have split caches. (which might explain why intel generally has much much better emulation performance, more so than their normal advantage would be)

theres been a lot of android on atom stuff announced in the last week or so by companies like acer and asus. it really looks like intel is going to start grabbing market share pretty quickly, at least with tablets and phablets

What, long time Intel slaves peddling new Intel stuff?

Who knew?

how could samsung go back to arm for tablets, much less make arm/exynos the "high end" option

Currently according to your link (we will see other benchmarks later) clovertrail+ is roughly the same speed as the quad cortex a15 in the i9500 and the qualcomm 600 at 1.9 ghz in the i9505.

If they are roughly the same speed, in tablets Samsung and other OEMs may still stick with ARM in android due to cost.

In phones or tablets with 4g Samsung and other OEMs may stick with ARM for the qualcomm has an integrated lte modem (currently the quad cortex a15 and qualcomm 600 lack the integrated modem, the qualcomm 800 will bring it back as well as making the chip faster.)

-------------------

I am glad to see competition, we are also going to be seeing tegra 4 coming out about the same time as clovertrail+ comes out.

Clovertrail+ is even the crappy one. What are they going to do when Bay Trail comes out?

ABI Research provided no details on the content and construction of their benchmarks,

They're going to show me more benchmarks between Clovertrail and Octa?

Hehe. The point was besides a single or two memory bound bm the huge atom gets crushed all over. Look eg. at the fpu scores.

You think its an octo core? so you add the 4x 0.45mm2 a7? Intel invest billions and billions to fight those 0.45mm2. Perhaps technically sweet but hardly the most sensible approach from a business perspective.
