NVIDIA claims INSANE speed in new 64-bit Tegra K1 (and RIP, Robin)


Here comes the wide-word to phones.

The chip company with the shouty name -- NVIDIA (NASDAQ:NVDA) -- unveils amazing ARM benchmarks. The 64-bit "Denver" Tegra K1 will be faster than anything else, claims the company -- even rivaling PC performance.

Thanks to clever just-in-time optimization, plus a plurality of pipelines, we may have some superfast hardware to play with, Real Soon Now.

In IT Blogwatch, bloggers dribble with anticipation. Not to mention: Robin Williams' best movie (IMHO)

Your humble blogwatcher curated these bloggy bits for your entertainment.


Agam Shah is no corrupt, puppet quasi-monarch:

Nvidia claims its 64-bit Denver chip will be..."the world's first 64-bit ARM processor for Android." ... It will have four Denver CPU cores and 192 Kepler graphics cores, which Nvidia says will provide PC-like performance [and] is "significantly outperforming" all its ARM-based rivals.

The chip isn't out yet though, of course, and there are no independent benchmark tests to verify his claims. So it remains to be seen if Nvidia will really out-gun Apple. ... It will operate at clock speeds up to 2.5GHz and has a "superscalar" design that provides more execution pipelines, so tasks can be executed in fewer clock cycles. ... Devices with the 64-bit Denver chip could be just around the corner.  MORE


Its improvement is interesting -- so says Simon Sharwood:

Denver will...offer a new technology NVIDIA calls “Dynamic Code Optimization,” [which] “optimizes frequently used software routines at runtime into dense, highly tuned microcode-equivalent routines. These are stored in a dedicated...cache.”

NVIDIA admits there's some overhead in this approach, but feels the overall performance improvement that comes with having optimised code ready to execute more than makes up for things. ... NVIDIA promises its partners will soon show off what it is possible to build on Denver. Those efforts should prove rather interesting, especially if they produce some high-powered Chromebooks. ... Google might be about to have itself a rather interesting ecosystem.  MORE


Jerry Hildenbrand notes that one of those partners may be Google itself:

The new chip, a sister to the current 32-bit Tegra K1, was designed for the highest single-core throughput possible, in a dual core ARMv8 package.

With rumors of an NVIDIA-powered 8-inch Nexus tablet so widespread, there's a good chance we just got a look at its processor.  MORE


But wait! Only dual core? Tim "O'Tato" Wrobel compares and contrasts:

While a few may be taken aback by its “dual-core” tag, don’t get held up on how many cores the chip features. As the company states, “the dual-CPU cores can attain significantly higher performance than existing four- to eight-core mobile CPUs on most mobile workloads.”

That’s exciting.  MORE


Meanwhile, Anyone gets déjà vu:

This dynamic recompilation stuff looks a bit like the old Transmeta Crusoë CPU.

This is indeed a bold move from nVidia to try this instead of a 'traditional' OoO core. ... Such design can perform brilliantly on small benchmarks, but be crushed on large, complex code.  MORE
