EVGA recently launched two new GTX 750 graphics cards with 2GB of GDDR5 memory. The new cards include a reference clocked GTX 750 2GB and a factory overclocked GTX 750 2GB SC (Super Clocked).
The new graphics cards are based around NVIDIA’s GTX 750 GPU with 512 Maxwell architecture CUDA cores. The GTX 750 is the little brother to the GTX 750 Ti we recently reviewed which has 640 cores. EVGA has clocked the GTX 750 2GB card’s GPU at reference clockspeeds of 1020 MHz base and 1085 MHz boost and memory at a reference speed of 1253 MHz. The “Super Clocked” GTX 750 2GB SC card keeps the memory at reference speeds but overclocks the GPU quite a bit to 1215 MHz base and 1294 MHz boost.
|EVGA GTX 750 2GB||EVGA GTX 750 2GB Super Clocked|
|GPU||512 CUDA Cores (Maxwell)||512 CUDA Cores (Maxwell)|
|- GPU Base||1020 MHz||1215 MHz|
|- GPU Boost||1085 MHz||1294 MHz|
|Memory||2 GB GDDR5 @ 1253 MHz on 128-bit bus|
1 x DVI, 1 x HDMI, 1 x DP
Both cards have a 55W TDP sans any PCI-E power connector and utilize a single shrouded fan heatsink. The cards are short but occupy two PCI slots. The rear panel hosts one DVI, one HDMI, and one DisplayPort video output along with ventilation slots for the HSF. Further, the cards both support NVIDIA’s G-Sync technology.
The reference clocked GTX 750 2GB is $129.99 while the factory overclocked model is $139.99. Both cards are similar to their respective predecessors except for the additional 1GB of GDDR5 memory which comes at a $10 premium and should will help a bit at high resolutions.

The NVIDIA GeForce GTX 750 Ti is fast but also power efficient, enough-so that Ryan found it a worthwhile upgrade for cheap desktops with cheap power supplies that were never intended for discrete graphics. Of course, this recommendation is about making the best of what you got; better options probably exist if you are building a PC (or getting one built by a friend or a computer store).

Tom's Hardware went another route: make it fanless.
After wrecking a passively-cooled Radeon HD 7750, which is probably a crime in Texas, they clamped it on to the Maxwell-based GTX 750 Ti. While the cooler was designed for good airflow, they decided to leave it in a completely-enclosed case without fans. Under load, the card reached 80 C within about twenty minutes. The driver backed off performance slightly, 1-3% depending on your frame of reference, but was able to maintain that target temperature.
Now, if only it accepted SLi, this person might be happy.

As we have talked about on several different occasions, Altcoin mining (anything that is NOT Bitcoin specifically) is a force on the current GPU market whether we like it or not. Traditionally, Miners have only bought AMD-based GPUs, due to the performance advantage when compared to their NVIDIA competition. However, with continued development of the cudaMiner application over the past few months, NVIDIA cards have been gaining performance in Scrypt mining.
The biggest performance change we've seen yet has come with a new version of cudaMiner released yesterday. This new version (2014-02-18) brings initial support for the Maxwell architecture, which was just released yesterday in the GTX 750 and 750 Ti. With support for Maxwell, mining starts to become a more compelling option with this new NVIDIA GPU.
With the new version of cudaMiner on the reference version of the GTX 750 Ti, we were able to achieve a hashrate of 263 KH/s, impressive when you compare it to the performance of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.
As you may know from our full GTX 750 Ti Review, the GM107 overclocks very well. We were able to push our sample to the highest offset configurable of +135 MHz, with an additional 500 MHz added to the memory frequency, and 31 mV bump to the voltage offset. All of this combined to a ~1200 MHz clockspeed while mining, and an additional 40 KH/s or so of performance, bringing us to just under 300KH/s with the 750 Ti.
As we compare the performance of the 750 Ti to AMD GPUs and previous generation NVIDIA GPUs, we start to see how impressive the performance of this card stacks up considering the $150 MSRP. For less than half the price of the GTX 770, and roughly the same price as a R7 260X, you can achieve the same performance.
When we look at power consumption based on the TDP of each card, this comparison only becomes more impressive. At 60W, there is no card that comes close to the performance of the 750 Ti when mining. This means you will spend less to run a 750 Ti than a R7 260X or GTX 770 for roughly the same hash rate.
Taking a look at the performance per dollar ratings of these graphics cards, we see the two top performers are the AMD R7 260X and our overclocked GTX 750 Ti.
However, when looking at the performance per watt differences of the field, the GTX 750 Ti looks more impressive. While most miners may think they don't care about power draw, it can help your bottom line. By being able to buy a smaller, less efficient power supply the payoff date for the hardware is moved up. This also bodes well for future Maxwell based graphics cards that we will likely see released later in 2014.

We finally saw Maxwell yesterday, with a new design for the SMs called SMM each of which consist of four blocks of 32 dedicated, non-shared CUDA cores. In theory that should allow NVIDIA to pack more SMMs onto the card than they could with the previous SMK units. This new design was released on a $150 card which means we don't really get to see what this new design is capable of yet. At that price it competes with AMD's R7 260X and R7 265, at least if you can find them at their MSRP and not at inflated cryptocurrency levels. Legit Reviews contrasted the performance of two overclocked GTX 750 Ti to those two cards as well as to the previous generation GTX 650Ti Boost on a wide selection of games to see how it stacks up performance-wise which you can read here.
That is of course after you read Ryan's full review.
"NVIDIA today announced the new GeForce GTX 750 Ti and GTX 750 video cards, which are very interesting to use as they are the first cards based on NVIDIA's new Maxwell graphics architecture. NVIDIA has been developing Maxwell for a number of years and have decided to launch entry-level discrete graphics cards with the new technology first in the $119 to $149 price range. NVIDIA heavily focused on performance per watt with Maxwell and it clearly shows as the GeForce GTX 750 Ti 2GB video card measures just 5.7-inches in length with a tiny heatsink and doesn't require any internal power connectors!"

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).
GM107 Block Diagram
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.
It wouldn’t be February if we didn’t hear the Q4 FY14 earnings from NVIDIA! NVIDIA does have a slightly odd way of expressing their quarters, but in the end it is all semantics. They are not in fact living in the future, but I bet their product managers wish they could peer into the actual Q4 2014. No, the whole FY14 thing relates back to when they made their IPO and how they started reporting. To us mere mortals, Q4 FY14 actually represents Q4 2013. Clear as mud? Lord love the Securities and Exchange Commission and their rules.
The past quarter was a pretty good one for NVIDIA. They came away with $1.144 billion in gross revenue and had a GAAP net income of $147 million. This beat the Street’s estimate by a pretty large margin. As a response, trading of NVIDIA’s stock has gone up in after hours. This has certainly been a trying year for NVIDIA and the PC market in general, but they seem to have come out on top.
NVIDIA beat estimates primarily on the strength of the PC graphics division. Many were focusing on the apparent decline of the PC market and assumed that NVIDIA would be dragged down by lower shipments. On the contrary, it seems as though the gaming market and add-in sales on the PC helped to solidify NVIDIA’s quarter. We can look at a number of factors that likely contributed to this uptick for NVIDIA.

Well this is somewhat unexpected (and possibly wrong). Maxwell, NVIDIA's new architecture to replace Kepler, is said to appear in Feburary with the form of a GeForce GTX 750 Ti. The rumors, which sound iffy to me, claims that this core will be produced at TSMC on a 28nm fabrication technology and later transition to their 20nm lines.
As if the 700-series family tree was not diverse enough.
2013 may have been much closer than expected.
Swedish site, Sweclockers, have been contacted by "sources" which claim that NVIDIA has already alerted partners to prepare a graphics card launch. Very little information is given beyond that. They do not even have access to a suggested GM1## architecture code. They just claim that partners should expect a new videocard on the 18th of February (what type of launch that is is also unclear).
This also raises questions about why the mid-range card will come before the high-end. If the 28nm rumor is true, it could just be that NVIDIA did not want to wait around until TSMC could fabricate their high-end part if they already had an architecture version that could be produced now. It could be as simple as that.
The GeForce GTX 750 Ti is rumored to arrive in February to replace the GTX 650 Ti Boost.

Yesterday we all saw the blog piece from NVIDIA that stated that they were going to start licensing their IP to interested third parties. Obviously, there was a lot of discussion about this particular move. Some were in favor, some were opposed, and others yet thought that NVIDIA is now simply roadkill. I believe that it is an interesting move, but we are not yet sure of the exact details or the repercussions of such a decision on NVIDIA’s part.
The biggest bombshell of the entire post was that NVIDIA would be licensing out their latest architecture to interested clients. The Kepler architecture powers the very latest GTX 700 series of cards and at the top end it is considered one of the fastest and most efficient architectures out there. Seemingly, there is a price for this though. Time to dig a little deeper.
Kepler will be the first technology licensed to third party manufacturers. We will not see full GPUs, these will only be integrated into mobile products.
The very latest Tegra parts from NVIDIA do not feature the Kepler architecture for the graphics portion. Instead, the units featured in Tegra can almost be described as GeForce 7000 series parts. The computational units are split between pixel shaders and vertex shaders. They support a maximum compatibility of D3D 9_3 and OpenGL ES 2.0. This is a far cry from a unified shader architecture and support for the latest D3D 11 and OpenGL ES 3.0 specifications. Other mobile units feature the latest Mali and Adreno series of graphics units which are unified and support DX11 and OpenGL ES 3.0.
So why exactly does the latest Tegras not share the Kepler architecture? Hard to say. It could be a variety of factors that include time to market, available engineering teams, and simulations which could dictate if power and performance can be better served by a less complex unit. Kepler is not simple. A Kepler unit that occupies the same die space could potentially consume more power with any given workload, or conversely it could perform poorly given the same power envelope.
We can look at the desktop side of this argument for some kind of proof. At the top end Kepler is a champ. The GTX 680/770 has outstanding performance and consumes far less power than the competition from AMD. When we move down a notch and see the GTX 660 Ti/HD 7800 series of cards, we see much greater parity in performance and power consumptions. Going to the HD 7790 as compared to the 650 Ti Boost, we see the Boost part have slightly better performance but consumes significantly more power. Then we move down to the 650 and 650 Ti and these parts do not consume any more power than the competing AMD parts, but they also perform much more poorly. I know these are some pretty hefty generalizations and the engineers at NVIDIA could very effectively port Kepler over to mobile applications without significant performance or power penalties. But so far, we have not seen this work.
Power, performance, and die area aside there is also another issue to factor in. NVIDIA just announced that they are doing this. We have no idea how long this effort has been going, but it is very likely that it has only been worked on for the past six months. In that time NVIDIA needs to hammer out how they are going to license the technology, how much manpower they must provide licensees to get those parts up and running, and what kind of fees they are going to charge. There is a lot of work going on there and this is not a simple undertaking.
So let us assume that some three months ago an interested partner such as Rockchip or Samsung comes knocking to NVIDIA’s door. They work out the licensing agreements and this takes several months. Then we start to see the transfer of technology between the companies. Obviously Samsung and Rockchip are not going to apply this graphics architecture to currently shipping products, but will instead bundle it in with a next generation ARM based design. These designs are not spun out overnight. For example, the 64 bit ARMv8 designs have been finalized for around a year, and we do not expect to see initial parts being shipped until late 1H 2014. So any partner that decides to utilize NVIDIA’s Kepler architecture for such an application will not see this part be released until 1H 2015 at the very earliest.
Sheild is still based on a GPU posessing separate pixel and vertex shaders. DX11 and OpenGL ES 3.0? Nope!
If someone decides to license this technology from NVIDIA, it will not be of great concern. The next generation of NVIDIA graphics will already be out by that time, and we could very well be approaching the next iteration for the desktop side. NVIDIA plans on releasing a Kepler based mobile unit in 2014 (Logan), which would be a full year in advance of any competing product. In 2015 NVIDIA is planning on releasing an ARM product based on the Denver CPU and Maxwell GPU. So we can easily see that NVIDIA will only be licensing out an older generation product so it will not face direct competition when it comes to GPUs. NVIDIA obviously is hoping that their GPU tech will still be a step ahead of that of ARM (Mali), Qualcomm (Adreno), and Imagination Technologies (PowerVR).
This is an easy and relatively painfree way to test the waters that ARM, Imagination Technologies, and AMD are already treading. ARM only licenses IP and have shown the world that it can not only succeed at it, but thrive. Imagination Tech used to produce their own chips much like NVIDIA does, but they changed direction and continue to be profitable. AMD recently opened up about their semi-custom design group that will design specific products for customers and then license those designs out. I do not think this is a desperation move by NVIDIA, but it certainly is one that probably is a little late in coming. The mobile market is exploding, and we are approaching a time where nearly every electricity based item will have some kind of logic included in it, billions of chips a year will be sold. NVIDIA obviously wants a piece of that market. Even a small piece of “billions” is going to be significant to the bottom line.
