Before getting into the performance of the $1000 NVIDIA TITAN it is worth looking at the improvements NVIDIA has added to this GK110 beast.  At 10.5" long it is a half inch longer than a 680 and a full 1.5" shorter than a 690, which allows it to fit in a wider variety of cases and the vastly improved thermals allow the usage of much smaller cases than other high end GPUs can manage without exotic cooling solutions.  There is also a reduction in noise generated, to the point where SLI'd TITANs run quieter than some single card solutions, not to mention much faster.  To take a look at just how much faster you can see [H]ard|OCP's results which you can compare to Ryan's results.

"NVIDIA is launching a TITAN today, literally, the new GeForce GTX TITAN video card is here, and we have a lot to talk about. We test single-GPU and 2-way SLI today, with more to follow later. We will find out if this TITAN of a video card really is worth it, and just who this video card is designed for. Be prepared to face the fastest single-GPU video card."

TITAN is back for more!

Our NVIDIA GeForce GTX TITAN Coverage Schedule:

If you are reading this today, chances are you were here on Tuesday when we first launched our NVIDIA GeForce GTX TITAN features and preview story (accessible from the link above) and were hoping to find benchmarks then.  You didn't, but you will now.  I am here to show you that the TITAN is indeed the single fastest GPU on the market and MAY be the best graphics cards (single or dual GPU) on the market depending on what usage models you have.  Some will argue, some will disagree, but we have an interesting argument to make about this $999 gaming beast.

A brief history of time...er, TITAN

In our previous article we talked all about TITAN's GK110-based GPU, the form factor, card design, GPU Boost 2.0 features and much more and I would highly press you all to read it before going forward.  If you just want the cliff notes, I am going to copy and paste some of the most important details below.

IMG_9502.JPG

From a pure specifications standpoint the GeForce GTX TITAN based on GK110 is a powerhouse.  While the full GPU sports a total of 15 SMX units, TITAN will have 14 of them enabled for a total of 2688 shaders and 224 texture units.  Clock speeds on TITAN are a bit lower than on GK104 with a base clock rate of 836 MHz and a Boost Clock of 876 MHz.  As we will show you later in this article though the GPU Boost technology has been updated and changed quite a bit from what we first saw with the GTX 680.

The bump in the memory bus width is also key, being able to feed that many CUDA cores definitely required a boost from 256-bit to 384-bit, a 50% increase.  Even better, the memory bus is still running at 6.0 GHz resulting in total memory bandwdith of 288.4 GB/s.

Speaking of memory - this card will ship with 6GB on-board.  Yes, 6 GeeBees!!  That is twice as much as AMD's Radeon HD 7970 and three times as much as NVIDIA's own GeForce GTX 680 card.  This is without a doubt a nod to the super-computing capabilities of the GPU and the GPGPU functionality that NVIDIA is enabling with the double precision aspects of GK110.

GK110 Makes Its Way to Gamers

Our NVIDIA GeForce GTX TITAN Coverage Schedule:

Back in May of 2012 NVIDIA released information on GK110, a new GPU that the company was targeting towards HPC (high performance computing) and the GPGPU markets that are eager for more processing power.  Almost immediately the questions began on when we might see the GK110 part make its way to consumers and gamers in addition to finding a home in supercomputers like Cray's Titan system capable of 17.59 Petaflops/s.

NVIDIA GeForce GTX 660 SE Information Comes Out

Subject: Graphics Cards | January 4, 2013 - 09:10 PM |
Tagged: nvidia, kepler, gk106, gtx 660 se

Are you ready for another entry to the confusing graphics market?  NVIDIA has you covered with the upcoming GeForce GTX 660 SE that will target the $180-200 market and hit the AMD Radeon HD 7870 1GB square in the jaw.  With the current lineup of GeForce cards that is the one area where NVIDIA is at an obvious disadvantage with the gap between the GTX 650 Ti and the GTX 660. 

As is usually the case, when a new graphics card is ready to hit the market, leaks occur in all directions.  Already we are seeing screenshots of specifications and benchmarks from PCEVA.  If the rumors are right you'll see the GTX 660 SE released in Q1 of 2013 with 768 CUDA cores, 24 ROPs and a 192-bit memory bus.  Interestingly, the GTX 660 SE will be based on GK106 and has the same core count as the GTX 650 Ti...the performance differences will be seen going from the 128-bit memory bus to 192-bit.  

660se-2.jpg

Current GPU-Z screenshots are showing a clock speed of 928 MHz with a Boost clock of 1006 MHz, running just about the same clock rates as the GTX 650 Ti (though the 650 series does not have GPU Boost technology enabled).  It also looks like the GTX 660 SE will use GDDR5 memory running 5.6 GHz and a 2GB capacity

660se-1.jpg

With CES just around the corner (we are leaving in the morning!) we will ask around and see if anyone has more information about a solid price point and time frame for release!

A look outside and in

We handle a fair amount of system reviews here at PC Perspective and use them mainly as a way to feature unique and interesting designs and configurations.  We know how the hardware will perform for the most part; doing extensive CPU and GPU testing on nearly a daily basis.  Sometimes we'll get systems in that are extremely budget friendly, other times vendors pass us machines that have MSRPs similar to a Kia automobile.  Then there are times, like today, we get a unique design that is a great mix of both.

AVADirect has had a Mini Gaming PC design for a while now but recently has gone through a refresh that adds in support for the latest Ivy Bridge processors, NVIDIA Kepler GPUs all using a new case from BitFenix that combines it in a smaller, mini-ITX form factor.

The quick specifications look like this:

  • BitFenix Prodigy chassis
  • Intel Core i7-3770K CPU, Overclocked at 4.4 GHz
  • ASUS P8Z77-I Deluxe Z77 Motherboard
  • EVGA GeForce GTX 680 2GB GPU
  • OCZ 240GB Vertex 3 SSD
  • Seagate 2TB SATA 6G HDD
  • 8GB Crucual DDR3-1866 Memory
  • Cooler Master 850 watt Silent Pro PSU

You'll also see a large, efficient Prolimatech cooler inside along with a Blu-ray burner and Windows 7 for a surprisingly reasonable $2100 price tag.

01.jpg

The BitFenix Prodigy chassis is a unique design that starts with sets of FiberFlex legs and handles surrounding the mini-ITX case.  The minor flexibility of the legs absorbs sound and impact on the table while the handles work great for picking up the system for LAN events and the like.  While at first I was worried about using them to support the weight of the rig, I had no problems and was assured by both BitFenix and by AVADirect it would withstand the torture.

NVIDIA's GTX 650 Ti, the new sub-$200 controller

Subject: General Tech | October 9, 2012 - 04:50 PM |
Tagged: gk106, gtx 650 Ti, kepler, nvidia

The sub-$200 GPU market just got a little more crowded with the arrival of NVIDIA's GTX 650 Ti, available for $160 on NewEgg.  That price matches an XFX HD 7850 if you include the $20 MIR, otherwise there are several other models available for around $180.  That establishes the competition as far as the cost to purchase but it is the performance competition that really matters.  The Tech Report tried out the overclocked GeForce GTX 650 Ti 2GB AMP! Edition from Zotac and the results did not favour NVIDIA, though in some cases the results were quite close.  In the end they felt that users deciding between these cards should ask themselves two questions; do you need the smaller physical size of the GTX 650 Ti for an SFF build and which game would you rather get for free, Assassin's Creed 3 or Sleeping Dogs?

You can read Ryan's full review here, if you haven't already.

"Nvidia's new GeForce GTX 650 Ti fills the last great gap in the 600-series lineup, offering Kepler goodness between $149 and 179 or so. We've taken one of the more upscale variants of the new card and delved inside the second to see how it stacks up against the competition."

Another GK106 Completes the Stack

It has been an interesting year for graphics cards and 2012 still has another solid quarter of releases ahead of it.  With the launch of AMD's 7000-series back in January, followed by the start of NVIDIA's Kepler lineup in March, we have had new graphics cards on a very regular basis ever since.  And while AMD's Radeon HD 7000 cards seemed to be bunched together a bit better, NVIDIA has staggered the release of the various Kepler cards, either because of capacity at the manufacturing facilities or due to product marketing plans - take your pick. 

Today we see the completion of the NVIDIA GeForce GTX 600 stack (if you believe the PR at NVIDIA) with the release of the GeForce GTX 650 Ti, a $150 graphics card that fills in the gap between the somewhat anemic GTX 650 and GT 640 cards and the most recently unveiled card, the GTX 660 2GB that currently sells for $229. 

01.jpg

The GTX 650 Ti has more in common with the GTX 660 than it does the GTX 650, both being based on the GK106 GPU, but is missing some of the unique features that NVIDIA has touted of the 600-series cards like GPU Boost.  Let's dive into the product and see if this new card will be the best option for those of you with $150 graphics budgets.

Zotac Rumored To Be Preparing Three GTX 650 Ti Graphics Cards

Subject: Graphics Cards | October 7, 2012 - 10:37 PM |
Tagged: nvidia, kepler, gtx 650ti, gpu, gk106-220

The NVIDIA GeForce GTX 650 Ti is rumored to launch soon, and so far specifications have leaked on the reference design as well as two custom cards from ASUS and Galaxy. Zotac is the latest manufacturer to have its GTX 650 Ti lineup leaked, and the company is bringing as many as three graphics cards to the GK106-220 Kepler family. In all, Zotac is rumored to be launching one 1GB GTX 650 Ti and two 2GB GPUs – all with vared levels of factory overclocks. Video outputs on all three cards include two DVI and two HDMI connectors.

Zotac GTX 650 Ti 2GB AMP Editon.jpg

The Zotac GTX 650 Ti 1GB stays close to the reference design, but bumps up the GPU core clockspeed to 941 MHz. It also includes 1 GB of GDDR5 memory on a 128-bit interface clocked at 1350 MHz (5400 MHz effective), which matches the reference design. The price of this card is said to be $160, and features a custom cooler from Zotac that is similar (but smaller than) to the cooler used on the company's GTX 660 Ti GPU wich we recently reviewed.

The Zotac GTX 650 Ti 2GB is, as the name suggests, a GTX 650 Ti graphics card with 2GB of GDDR5 memory. It features Zotac's custom cooler, and a single PCI-E 6-pin power connector. The GPU clockspeed is 941 MHz and the memory clockspeed is 1350 MHz. The extra 1GB of graphics memory is nice, but it is still on a 128-bit interface so don't expect too much of a performance boost. MSRP of this card is rumored to be $180.

Finally, the GTX 650 Ti 2GB AMP! Edition is Zotac's highest-end GTX 650 Ti graphics card. It comes with the GK106-220 Kepler GPU and 2GB of GDDR5 memory on a 128-bit bus. Powered by a single 6-pin PEG connector, the factory overclocked graphics card is clocked at 1033 MHz for the GPU and 1550 MHz (6200 MHz effective) for the memory.The Zotac GTX 650 Ti AMP! Edition comes with the company's custom cooler and is the first card to feature factory overclocked memory. The rumored price of this card is $190. Unfortunately, that puts it fairly close to the price of a reference GTX 660, which may make this card a hard sell. The factory overclocks are impressive, but saving up the extra $30 needed to get a GTX 660 is likely a better idea because it will still offer up better performance thanks to the additional CUDA cores and wider memory bus.

The following chart compares the three Zotac cards to the leaked reference specifications.

  Reference Specifications Zotac GTX 650 Ti 1GB Zotac GTX 650 Ti 2GB Zotac GTX 650 Ti 2GB AMP! Edition
CPU Clockspeed 925 MHz 941 MHz 941 MHz 1033 MHz
Memory Clockspeed 1350 MHz 1350 MHz 1350 MHz 1550 MHz
GDDR5 Amount 1 GB 1 GB 2 GB 2 GB
Price ~$140 $160 $180 $190

Comparison of several GTX 650 Ti graphics cards versus the rumored reference specifications.

Further, this chart compares the leaked specifications of the top end cards from each manufacturer (at least, the ones we know of so far) to the highest-end Zotac GPU: the 2GB AMP! Edition.

  Reference Specifications ASUS GTX 650 Ti TOP Galaxy GTX 650 Ti GC 1GB Gigabyte GTX 650 Ti OC Zotac GTX 650 Ti 2GB AMP! Edition POV GTX 650 Ti 1GB Ultra Charged
CPU Clockspeed 925 MHz 1033 MHz 966 MHz 1032 MHz 1033 MHz 1058 MHz
Memory Clockspeed 1350 MHz 1350 MHz 1350 MHz 1350 MHz 1550 MHz 1350 MHz
GDDR5 Amount 1 GB 1 GB 1 GB 2 GB 2 GB 1 GB
Video Outputs 2 x DVI, 1 x HDMI 2 x DVI, 1 x HDMI, 1 x VGA 2 x DVI, 1 x HDMI 2 x DVI, 1 x HDMI, 1 x VGA 2 x DVI, 2 x HDMI 1 x DVI, 1 x HDMI, 1 x VGA
Price ~$140 €206 (~$267?) $150 €169 $190 unkown

Inno3D is also rumored to have a GTX 650 Ti graphics card coming out, but we don't know clockspeeds or price on it. Only that it has two DVI and one HDMI connector, a single PEG power connector, and a custom cooler.

Overall, the Zotac card measures up well, with pricing being the only major disadvantage. The 2GB of memory, factory overclocks, and two HDMI ports are welcome additions, however. Interestingly, the Zotac card is not the highest clocked graphics card overall, but it is the only one that features overclocked memory. It is unclear to me why manufactuers of NVIDIA cards are so hesitant to push the memory clockspeeds (or if they are even allowed to), but Zotac seems to prove that it is possible to do so. 

Also worth pointing out is the rumored pricing, as some of these custom graphics cards are pushing $200 (especially the ASUS card when coverted to USD... I'm sure that has to be in error...), and reference GTX 660 with the full GK106 Kepler core are only $230. It will be interesting to see if these rumored prices turn out to be true, and how well Zotac's factory overclocked 650 Ti models sell.

New Specifications Leak For GTX 650 Ti, Launch Likely Imminent

Subject: General Tech | October 4, 2012 - 10:08 PM |
Tagged: nvidia, kepler, gtx 650ti, gpu, geforce

Earlier this year, specifications for an as-yet-unreleased GTX 650 Ti graphics card from NVIDIA leaked. At the time, the rumors indicated that the GTX 650 Ti would have hardware closer to the GTX 650 than the GTX 660 but still be based on the GK106 Kepler chip. It would have a 128-bit memory interface, 48 testure units, and 576 CUDA cores in 1.5 GPCs (3 SMX units). And to top it off, it had a rumored price of around $170! Not exactly a bargain.

Welll, as the launch gets closer more details are being leaked, and this time around the rumored information is indicating that the GTX 650 Ti will be closer in performance to the GTX 660 and cost around $140-$150. That certainly sounds better!

inno3d GTX 650Ti.jpg

The new rumors are indicating that the reference GTX 650 Ti will have 768 CUDA cores, and 64 texture units, which means it has the full two GPCs (so it is only missing the one-half of a GPC that you get with GTX 660). and four SMX units. As a point of reference, the GTX 660 – which NVIDIA swears is the full GK106 chip – has five SMX units in 2 and a half GPCs.

The following image shows the layout of the GTX 660. The GTX 650 Ti will have the GPC on the far right disabled. Previous rumors suggested that the entire middle GPC would be turned off, so the new rumors are definitely looking more promising in terms of potential performance.

GeForce_GTX_660_Block_Diagram_FINAL.png

Specifically marked GK106-220 on the die, the GTX 650 Ti is based the same GK106 Kepler chip as the GTX 660, but with some features disabled. The GPU is reportedly clocked at 925MHz, and it does not support NVIDIA's GPU Boost technology.

GTX 650Ti.jpg

Memory performance will take a large hit compared to the full GK106 chip. The GTX 650 Ti will feature 1GB of GDDR5 memory clocked at 1350MHz on a 128-bit memory interface. That amounts to approximately 86.4 GB/s bandwidth, which is slightly over half of the GTX 660's 144.2 GB/s bandwidth. Also, it's just barely over the 80 GB/s bandwidth of the GTX 650 (which makes sense, considering they are both using 128-bit interfaces).

new GeForce GTX 650 Ti Specifications Leak.png

The latest rumors indicate the GTX 650 Ti will be priced at around $140 with custom cards such as recently leaked Galaxy GTX 650 Ti GC on Newegg costing more ($149). These new leaked specifications have more weight than the previous rumors since they have come from multiple leaks from multiple places, so I am hoping that these new rumors are the real deal. If so, the GTX 650 Ti becomes a much better value that it was rumored to be before!

Gigabyte Launches Three New Factory Overclocked Kepler GPUs

Subject: Graphics Cards | October 4, 2012 - 04:42 PM |
Tagged: nvidia, kepler, gtx 680, gtx 670, gtx 660 Ti, gigabyte, factory overclocked

Gigabyte is launching three new factory overclocked graphics cards featuring a Kepler GPU, custom PCB, and custom cooler. The factory overclocks are notable, but will cost you. Specifically, the company is producing versions of the GTX 660 Ti, GTX 670, and GTX 680.

GTX 680.jpg

The Gigabyte GV-N680OC-4GD takes the GTX 680 GPU, places it on a custom PCB, and pairs it with 4GB of GDDR5 memory. It features two 6-pin PCI-E power connectors, and Gigabyte’s Windforce X3 450W custom cooler using a triangular fin design that allegedly increases cooling potential. While the GDDR5 memory clockspeeds have not been increased over the reference clocks, the GPU core and boost clockspeeds have been pushed to 1071 MHz and 1137 MHz respectively. The following chart shows the differences in clockspeed and memory over the reference design.

  Reference GTX 680 Gigabyte N680OC-4GD
GPU Core 1006 MHz 1071 MHz
GPU Boost 1058 MHz 1137 MHz
GDDR5 Amount 2 GB 4 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $500 $800 (rumored)

 

The GTX 680 is not the only card to get a custom makeover by Gigabyte, however. The GV-N670OC-4GD is a custom GTX 670. With this card, Gigabyte has set the base clockspeed at 980 MHz – the boost clockspeed of reference cards – and the boost clockspeed at 1058 MHz. Gigabyte has also doubled down on the GDDR5 memory by packing 4GB onto the custom PCB. The memory clockspeed remains the same 6 Gbps as reference cards, however.

GTX 670.jpg

This card uses the same Windforce X3 cooler as the cust GTX 680, and as a result has a triple slot design that looks identical to the N680OC-4GD. If you look just above the PCI-E connector though, you can see tell them apart by the product name.

  Reference GTX 670 Gigabyte N670OC-4GD
GPU Core 915 MHz 980 MHz
GPU Boost 980 MHz 1058 MHz
GDDR5 Amount 2 GB 4 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $400 $550 (rumored)

 

Finally, we have the GV-N66TOC-3GD which overclocks the GTX 660 Ti GPU to the max. Factory clockspeeds are set at 1032 MHz base and 1111 MHz boost. Memory also sees a small bump from 2GB reference to 3GB. On the other hand, the memory is not overclocked and remains at the reference 6 Gbps clockspeed. This card also has a triple fan Windforce cooler, however this version is not the triple slot design found on the GTX 670 and GTX 680s SKUs – only dual slot.

  Reference GTX 660 Ti Gigabyte N66TOC-3GD
GPU Core 915 MHz 1032 MHz
GPU Boost 980 MHz 1111 MHz
GDDR5 Amount 2 GB 3 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $300 $415 (rumored)

 

All three of the Gigabyte GPUs feature two DVI, one full-size HDMI, and one full-size DisplayPort connector for video outputs. 

All three factory overclocked graphics cards feature respectable GPU overclocks, and it appears that Gigabyte has provided ample cooling for each GPU. The triple slot, triple fan version on the N670OC-4GD and N680OC-4GD in particular seem to offer headroom above even what Gigabyte has clocked these out of the box. Curiously though, Gigabyte is continuing the trend of not touching the memory clockspeed of Kepler cards. It may be that the RAM chips are already at their max on the reference design, or there could be some behind the scenes talk with NVIDIA not waning Add In Board partners to touch the memory Unfortunately, all I have at this point is speculation, but it is a rather curious omission on such high end cards. That point becomes clearer when price is taken into consideration. Videocardz claims to have the pricing information for the three video cards, and the custom cards are going to cost you a large premium over reference cards. The rumored prices can be found in the charts above compared against the reference pricing, but the basic run down is that the GV-N66TOC-3GD will cost $415, the GV-N670OC-4GD will cost $550, and the GV-N680OC-4GD will cost (an astounding) $800.

I’m hoping that the rumored prices are in error and will be adjusted once the cards are available. These are neat cards that look to have plenty of cooling, but I’m still trying to figure out just what these cards have to offer to justify the huge jump over reference pricing. And, no, the superfluous gold plated HDMI connectors do not count. [For example, the 4GB Galaxy GTX 670 we recently reviewed was only $70 over reference while the Gigabyte card is rumored to be $150!]
