An Upgrade Project

When NVIDIA started talking to us about the new GeForce GTX 750 Ti graphics card, one of the key points they emphasized was the potential use for this first-generation Maxwell GPU to be used in the upgrade process of smaller form factor or OEM PCs. Without the need for an external power connector, the GTX 750 Ti provided a clear performance delta from integrated graphics with minimal cost and minimal power consumption, so the story went.

Eager to put this theory to the test, we decided to put together a project looking at the upgrade potential of off the shelf OEM computers purchased locally.  A quick trip down the road to Best Buy revealed a PC sales section that was dominated by laptops and all-in-ones, but with quite a few "tower" style desktop computers available as well.  We purchased three different machines, each at a different price point, and with different primary processor configurations.

The lucky winners included a Gateway DX4885, an ASUS M11BB, and a Lenovo H520.

What we know about Maxwell

I'm going to go out on a limb and guess that many of you reading this review would not have normally been as interested in the launch of the GeForce GTX 750 Ti if a specific word hadn't been mentioned in the title: Maxwell.  It's true, the launch of GTX 750 Ti, a mainstream graphics card that will sit in the $149 price point, marks the first public release of the new NVIDIA GPU architecture code named Maxwell.  It is a unique move for the company to start at this particular point with a new design, but as you'll see in the changes to the architecture as well as the limitations, it all makes a certain bit of sense.

For those of you that don't really care about the underlying magic that makes the GTX 750 Ti possible, you can skip this page and jump right to the details of the new card itself.  There I will detail the product specifications, performance comparison and expectations, etc.

If you are interested in learning what makes Maxwell tick, keep reading below.

The NVIDIA Maxwell Architecture

When NVIDIA first approached us about the GTX 750 Ti they were very light on details about the GPU that was powering it.  Even though the fact it was built on Maxwell was confirmed the company hadn't yet determined if it was going to do a full architecture deep dive with the press.  In the end they went somewhere in between the full detail we are used to getting with a new GPU design and the original, passive stance.  It looks like we'll have to wait for the enthusiast GPU class release to really get the full story but I think the details we have now paint the story quite clearly.  

During the course of design the Kepler architecture, and then implementing it with the Tegra line in the form of the Tegra K1, NVIDIA's engineering team developed a better sense of how to improve the performance and efficiency of the basic compute design.  Kepler was a huge leap forward compared to the likes of Fermi and Maxwell is promising to be equally as revolutionary.  NVIDIA wanted to address both GPU power consumption as well as finding ways to extract more performance from the architecture at the same power levels.  

The logic of the GPU design remains similar to Kepler.  There is a Graphics Processing Cluster (GPC) that houses Simultaneous Multiprocessors (SM) built from a large number of CUDA cores (stream processors).

Readers familiar with the look of Kepler GPUs will instantly see changes in the organization of the various blocks of Maxwell.  There are more divisions, more groupings and fewer CUDA cores "per block" than before.  As it turns out, this reorganization was part of the ability for NVIDIA to improve performance and power efficiency with the new GPU.

The Mini ITX Surge Continues

For years now the enthusiast crowd has been clamoring for Corsair to bring its case building prowess down to the Mini ITX market and with the Obsidian 250D it has done just that.  By combining the design features that have make Corsair's units so popular with the aesthetic touches of the most recent Obsidian lineup, the 250D is an interesting and combination of size and performance.

The Corsair 250D is unlike most other Mini ITX designs out today in that it supports a lot of full size components.  You'll be able to use a standard ATX power supply, many self contained water coolers, full size graphics card and won't have to suffer through the most painful cable routing aspects of other small form factor cases.

Video Perspective: Free to Play Games on the A10-7850K vs. Intel Core i3 + GeForce GT 630

Subject: Graphics Cards, Processors | January 31, 2014 - 04:36 PM |
Tagged: 7850k, A10-7850K, amd, APU, gt 630, Intel, nvidia, video

As a follow up to our first video posted earlier in the week that looked at the A10-7850K and the GT 630 from NVIDIA in five standard games, this time we compare the A10-7850K APU against the same combination of the Intel and NVIDIA hardware in five of 2013's top free to play games.

UPDATE: I've had some questions about WHICH of the GT 630 SKUs were used in this testing.  Our GT 630 was this EVGA model that is based on 96 CUDA cores and a 128-bit DDR3 memory interface.  You can see a comparison of the three current GT 630 options on NVIDIA's website here.

If you are looking for more information on AMD's Kaveri APUs you should check out my review of the A8-7600 part as well our testing of Dual Graphics with the A8-7600 and a Radeon R7 250 card.

Video Perspective: 2013 Games on the A10-7850K vs. Intel Core i3 + GeForce GT 630

The most interesting aspect of the new Kaveri-based APUs from AMD, in particularly the A10-7850K part, is how it improves mainstream gaming performance.  AMD has always stated that these APUs shake up the need for low-cost discrete graphics and when we got the new APU in the office we did a couple of quick tests to see how much validity there to that claim.

In this short video we compare the A10-7850K APU against a combination of the Intel Core i3-4330 and GeForce GT 630 discrete graphics card in five of 2013's top PC releases.  I think you'll find the results pretty interesting.

UPDATE: I've had some questions about WHICH of the GT 630 SKUs were used in this testing.  Our GT 630 was this EVGA model that is based on 96 CUDA cores and a 128-bit DDR3 memory interface.  You can see a comparison of the three current GT 630 options on NVIDIA's website here.

Lenovo introduces a unique form factor

Lenovo isn't a company that seems interested in slowing down.  Just when you think the world of notebooks is getting boring, it releases products like the ThinkPad Tablet 2 and the Yoga 2 Pro.  Today we are looking at another innovative product from Lenovo, the Yoga Tablet 8 and Yoga Tablet 10.  While the tablets share the Yoga branding seen in recent convertible notebooks these are NOT Windows-based PCs - something that I fear some consumers might get confused by.  

Instead this tablet pair is based on Android (4.2.2 at this point) which brings with it several advantages.  First, the battery life is impressive, particularly with the 8-in version that clocked in more than 17 hours in our web browsing test!  Second, the form factor of these units is truly unique and not only allows for larger batteries but also a more comfortable in-the-hand feeling than I have had with any other tablet.  

Check out the video overview below!  

You can pick up the 8-in version of the Lenovo Yoga Tablet for just $199 while the 10.1-in model starts at $274.

The Lenovo Yoga Tablet is available in both 8-in and 10.1-in sizes though the hardware is mostly identical between both units include screen resolution (1280x800) and SoC hardware (MediaTek quad-core Cortex-A7).  The larger model does get an 8000 mAh battery (over the 6000 mAh on the 8-in) but isn't enough to counter balance the power draw of the larger screen.

IMG_9329.JPG

The 1280x800 resolution is a bit lower than I would like but is perfectly acceptable on the 8-in version of the Yoga Tablet.  On the 10-in model though the pixels are just too big and image quality suffers.  These are currently running Android 4.2.2 which is fine, but hopefully we'll see some updates from Lenovo to more current Android versions.
