Kal-El Tegra SoC to use 5 cores

Recent news from NVIDIA has unveiled some interesting new technical details about the upcoming Kal-El ARM-based Tegra SoC.  While we have known for some time that this chip would include a quad-core processor and would likely be the first ARM-based quad-core part on the market, NVIDIA's Matt Wuebbling spilled the beans on a new technology called "Variable SMP" (vSMP) and a fifth core on the die.

This patented technology allows the upcoming Tegra processor to address a couple of key issues that affect smartphones and tablets: standby power consumption and manufacturing process deviations.  Even though all five of the cores on Kal-El are going to be based on the ARM Cortex A9 design they will have very different power characteristics due to variations in the TSMC 40nm process technology that builds them.  Typical of most foundries and process technologies, TSMC has both a "high performance" and a "low power" derivative of the 40nm technology usually aimed at different projects.  The higher performing variation will run at faster clock speeds but will also have more transistor leakages thus increasing overall power consumption.  The low power option does just the opposite: lowers the frequency ceiling while using less power at idle and usage states.

NVIDIA's answer to this dilemma is to have both - a single A9 core built on the low power transistors and quad A9s built on the higher performing transistors.  The result is the diagram you saw at the top of this story with a quad-core SoC with a single ARM-based "companion."  NVIDIA is calling this strategy Variable Symmetric Multiprocessing and using some integrated hardware tricks it is able to switch between operating on the lower power core OR one to four of the higher power cores.  The low power process will support operating frequencies up to only 500 MHz while the high speed process transistors will be able to hit well above 1-1.2 GHz.

Kepler has arrived ... sort of

Tagged: nvidia, kepler, GK117, GK107

The news on the street is that two chips from NVIDIA's Kepler lineup should be arriving relatively soon, but don't get too excited.  The GK117 will be a hybrid Fermi/Kepler card, not a GPU but perhaps a powerful addition to any render farm or other application which can benefit the new architecture.  It could also just be a test chip the NVIDIA created to test the integration capabilities of the two architectures.  The GK107 seems to likely be a mobile part, something SemiAccurate dismisses quickly as it will have to compete with the integrated GPUs present in both AMD and Intel mobile chips. 

There is no sign of the Kepler everyone is waiting for, the GPU that will power NVIDIA's next generation of graphics cards.  Why haven't we seen any sign of it yet?  Drop by SemiAccurate for speculation on some of the possible reasons.

"Nvidia has two Kepler parts taped out and likely back in house by now. They are however, not the fire-breathing big chips you would expect.

Sources tell SemiAccurate that the first Kepler chips taped out about three months after the first 28nm Fermi shrink taped out. If you remember when we exclusively told you about the dates on those about a month ago, now there are a few more details to add."

A new trick from an old card, five displays from a single GTX560 Ti

Subject: Graphics Cards | September 12, 2011 - 12:26 PM |
Tagged: gtx560 ti, nvidia, nvidia surround, gtx560 ti mdt x5, galaxy

The GTX560Ti MDT X5 (Multi Display Technology) can handle sending signal to 5 displays simultaneously which is something that no NVIDIA card could do before.  AMD had the only GPUs which could handle multiple displays, you needed an SLI setup to manage NVIDIA Surround.  [H]ard|OCP were lucky enough to get to play with this $330 mid-range GPU that knows a new trick and were suitably impressed by its ability to provide good gaming performance on three 1080p monitors.  They also mention a GeForce 210 model that can handle up to four monitors for the non-gamer.

"With the new Galaxy GeForce GTX560Ti MDT X5 video card it is possible to output to 5 displays even though this is a single GPU video card. Enjoy NVIDIA multi-display spanned resolution gaming without the need for two cards! Can this GTX 560 Ti based video card stand up in the latest games when spanned across three displays? We are surprised."

GPU-Z Releases Version 0.5.5 With Improved Support for AMD and Nvidia Graphics Cards

Subject: General Tech | September 6, 2011 - 01:32 AM |
Tagged: gpu, hardware, Utility, windows, amd, Intel, nvidia

GPU-Z is a fine little Windows utility that, much like its CPU-Z brethren, can tell you all sorts of useful information about your graphics sub-system. The lightweight program does not require a restart, and weighs in at 922 KB. GPU-Z is distributed by TechPowerUp, and is now officially on it’s 0.5.5 version.

The new version adds support for a slew of AMD and Nvidia graphics cards, improved support for BIOS identification, and a new tab for a giveaway by graphics card vendor PowerColor. On the AMD front, the new version adds support for the companies line of A-Series APU graphics cores, AMD’s mobile cayman GPU “Blackcomb,” and various FirePro cards including the V8000, V3700, and 2460 (FireMV). On the Nvidia side of things, the new version adds support for the GeForce GT 530, GT 545, GT 560 Ti OEM, Quadro 400, Quadro 4000M, and Quadro 5000. Further, GPU-Z updated support for mobile versions of Nvidia cards, including the GeForce GT 305M, 410M, 520M, 520MX, 555M, and the GTX 580M.

The program further improves the BIOS readings of Nvidia cards as well as fixing a shader count detection bug on the Blackcomb mobile Cayman AMD parts. The ASUS MARS II GPU also receives support in version 0.5.5. PowerColor is holding a giveaway for a 6990 graphics card to a lucky winner. The new GPU-Z tab has all the relevant information as well as an entry form. Lastly, the program will now remember the last selected GPU selected from the drop down on multi-GPU systems.

The updated support is nice, and the lightweight program starts up just as fast as the previous versions. Do you use GPU-Z?  You can download the new version here.

Is a GTX 590 just not enough for you?

A Legacy of Unique Engineering

ASUS has often been one of only a handful of companies that really pushes the limits of technology on their custom designed products including graphics cards, sound cards, notebooks, motherboards and more.  Just a little over a year ago I wrote a review of the ASUS ARES Dual Radeon HD 5870 graphics card - the first of its kind and it was labeled the "Ultimate Graphics Card" at the time.  Life on the top of mountain doesn't last that long in the world of the GPU though and time (and the GTX 590 and HD 6990) left the Greek god of war in the rearview mirror.

asus01.jpg

This time around we have a successor to the MARS - the NVIDIA version that combines two top-level GPUs on a single PCB.  The new ASUS MARS II we are reviewing today is a pair of binned GTX 580 GPUs paired together for full-time SLI and built with a limited edition run of 999 units.  In many ways the MARS II and the ARES share a lot of traits: custom designed cooling and PCB, a unique aesthetic design, limited edition status and significant physical weight as well.  Of course, the price tag is also pretty high and if you aren't comfortable reading about a $1300 graphics card you might as well turn around now...  For those that dare though, you can be sure that the MARS II will have you dreaming about PC gaming power for years to come!

We now know about NVIDIA's New Years presents

Subject: General Tech | August 24, 2011 - 11:09 AM |
Tagged: nvidia, fermi, kepler, leak

There is good news and bad news out of SemiAccurate about NVIDIA today.  The bad news is that the chips are all Fermi, they have simply been shrunk to 28nm from 40nm.  That makes the idea of mobile variants arriving first very probable with the respectably low TDP shown on the leaked chart.  There at the bottom, in the row with the most question marks are the higher powered chips.   The good news is that the list is incomplete, there is more in store for consumers in the same time frame.  They will likely be 40nm but they will definitely not be Kepler chips.

"What does Nvidia (NASDAQ:NVDA) have coming up for the post-Christmas GPU line? You have heard a lot about the 28nm parts, and here is what you will be seeing.

The short story is this, Nvidia is putting out a bunch of Fermi shrinks on 28nm, and you will likely see the mobile variants first. They are as follows, with some information a bit blurred to protect the exact sub-species of mole involved."

Can two overclocked GTX 550 Ti's beat the competition?

Subject: Graphics Cards | August 23, 2011 - 03:33 PM |
Tagged: nvidia, gtx550 ti, msi, sli, N550GTX-Ti Cyclone II

If you put a limit of $300 on your graphics subsystem, you are most likely shopping for an HD6950 or possibly a heavily overclocked GTX 560 Ti or a discounted GTX570.  [H]ard|OCP tested out a different choice, two of MSI's N550GTX-Ti Cyclone II card in SLI, which can also be had for under $300.   The testing did not go so well for NVIDIA's less powerful card, the HD6950 won in almost every test and consumed less energy doing so.  There were certain situations in which they would recommend running the cards in SLI, specifically when you already own a GTX 550 or other lower powered NVIDIA card and don't plan on playing at resolutions above 1920x1200.  Only then would this upgrade make sense.

"Packing a GeForce GTX 550 Ti GPU each, we have a pair of N550GTX-Ti Cyclone II video cards that we are going to evaluate against a Radeon HD 6950, GeForce GTX 570 and even an overclocked GeForce GTX 560 Ti. At a total cost of only $260 we will find out if this dual-GTX 550 Ti action has what it takes to compete. "
