Maxwell GeForce GTX 750 And GeForce GTX 750 Ti Official Specs Revealed

Written by Paulo Proenca on Sun, Feb 16, 2014 5:00 PM

It's official; both the Nvidia GeForce GTX 750 & GeForce GTX 750 Ti are ready and could make their way to a gaming PC near you very soon. Both cards will mark NVIDIA's new Maxwell architecture's first appearance.

We now have the first concrete details on the Maxwell architecture, including the specifications Of Nvidia's new Maxwell based GPUs that sees the chip giant make new strides in terms of energy efficiency...

First, let's take a look at the shader performance, energy efficiency and core configuration of the 28nm Maxwell Cores.

1. The First Revision of the Maxwell Architecture

1.1 Shader Performance & Energy Effiency

135% Performance Per Core Over Kepler - That's right. Maxwell Cores are in theory very powerful. We are looking at a much larger L2 Cache and, among other improvements, even faster video decoding and encoding. What does 135% mean? It means that one Shader Processing Unit (roughly) is 1.35 times faster than one Kepler Core. This means that a Maxwell Graphics Card might have less Shader Processing Units than a Kepler Graphics Card and yet perform better. It's pretty much what we saw happening when Nvidia moved from Fermi to Kepler.

2X Performance per Watt: Maxwell Cores are even more energy efficient. We will see that by looking at the GeForce GTX 750 Ti's rated TDP board. Not only does the GPU not require any power connectors whatsoever (!), but it performs better than GeForce GTX 650 Ti. How can a graphics card that relies entirely on the PCI slot for power, be so powerful?

1.2 Core Configuration

The First Maxwell core to make an appearance is the GM107. The latter will offer 128 Shader Processing Units and 8 TMUs per SMX. The Maxwell core also features two 64-bits memory controllers and 16 ROPs. Thus, the most powerful version of the GM107 chip used on the GeForce GTX 750 Ti will offer 640 Shader Processing Units (128 x 5), 40 TMUs (8 x 5) and 16 ROPs.

The GM107 Core is built using a 28nm technology, with only the second revision cores of the Maxwell architecture set to make use of the upcoming 20nm fabrication process. This will be used on the more powerful cards, such as the GeForce GTX 860 Ti to GeForce GTX 880 range.

2. Meet the GeForce GTX 750 & GeForce GTX 750 Ti

AMD has been flooding the market in recent months with their competitive mainstream graphics cards. The Radeon R7 250 for those gaming on a tight budget, the recently released Radeon R7 250X, and of course the Radeon R7 260 & Radeon R7 260X for the 1080p gaming enthusiasts who don't want to splash out $300.

Now, NVIDIA is countering AMD's recent reign with two graphics cards of their own: the GeForce GTX 750, recommended for eye-candy gaming at 720p, and the GeForce GTX 750 Ti, for reasonable gaming at 1080p resolution.

2.1 GeForce GTX 750

 

The GeForce GTX 750 succeeds the well-loved GeForce GTX 650. In comparison to its predecessor we are looking at roughly 33% more Shader Processing Units which, as said above, are more powerful. The card should be over 20% faster than the GeForce GTX 650 and offer very solid performance. The TDP is even lower than the already efficient GeForce GTX 650; even lower-end PSUs will be up the job of powering this .

However, not everything is roses. The Memory Bandwidth remains the same and at a peak transfer of 80.0 GB/s. This is still very good value but the card will not be able to perform very well when gaming at 1080p. You might want to think twice if you're looking to game at that resolution. Furthermore, the 2GB versions will be bottlenecked by the Core itself and will be used as marketing to lure consumers into paying more for what is essentially the same product.

GeForce GTX 750 looks to be the perfect choice for those tight-budgeted folks using integrated or entry-level graphics.

2.2 GeForce GTX 750 Ti

The GeForce GTX 750 Ti technically succeeds the GeForce GTX 650 Ti and the GeForce GTX 650 Boost Edition. The configuration is actually inferior: 640 Shader Processing Units against 768. However, and as repeatedly said above, these are more powerful. That fact paired with higher core-clock frequencies leads to a reasonable performance boost over its predecessor.

What makes the GeForce GTX 750 Ti very appealing is its extremely low rated board TDP. You won't find anywhere in the market a GPU this powerful with such a small power consumption and heat dissipation.

Again, the memory bandwidth remains the same and even with such power, the 2GB versions might not offer enoughextra performance over the 1GB variation.

The GeForce GTX 750 Ti is a worthy replacement for gamers still spoting the old GeForce GTS 450 or Radeon HD 5670 GPUs, as they will get an over 30% performance boost and in all honesty won't need a new PSU.

So, what do you think? Impressed by the extremely low rated board TDP? Perhaps you expected more performance..or maybe what you really want to know is the price? Let us know below!

@AntonSchoeman - Yeah, same here. I hope a 3rd party brings a 192bit version out at the very least. But whoever could release a 256-bit 750Ti 2GB while still making good profit, would easily own the budget next-gen PC market.

@Talhkora - Good spot, I meant to to say R7's, sorry. However, I'm sick of new 'gimmicks' being released that simply can't live up to their price points. You'll pretty much be paying for an extra GDDR5 that your games won't make use of.

Yeah that always happen, and seems it is working cuz still some people thibk having more VRAM makes the card better, example my brother got an laptop with low end HD6000 series with 1GB VRAM ddr3 which the gfx cant use all but he though its a great card until I told him. XD

Yeah and what a lot of people don't realise is that low bus shared out between more GDDR5 means...even worse performance than a lower GDDR5 card! At the moment the R9 270 gives some of the best budget GPU/Core Clock/Bus specs :)

Yeah and the new R7 265 too, I am considering to get R9 270 as the X version needs two pin while my psu CX430 has only one 6pin which is enough for non X and that card will be fine for me as I don't play demandig games and the card costs €200 which is cheap in my country as it was that price since it released in the stores. :)

Nice. I'll also have to keep my eye on the R7 265 as well. They're saying it will have 256-bit memory bus. If the core clock is high enough, AMD may have just countered the 750Ti before Nvidia even complete full shipment...

I don't quite get it. GTX 550 Ti supported SLI. 550 Ti AND 650 Ti both had a 192-bit memory bus. How come the GTX 750 Ti has only 128-bit memory bus? Would have been even more powerful had they used a 192-bit memory bus and supported SLI. Sure, they want to keep the costs as low as possible but why suddenly downgrade the mem bus? Hopefully a revised version gets to be released on a later day.

I agree. 128-bit is a bit of a let down. If they want to really compete with the R9's, they'll need to at least equip the 750 Ti with 256-bit. We're in the next-gen now. Every GB of GDDR5 counts!

Both GTX are competing with R7 cards not R9, that's why they have 128bit and cost cheaper, you forgot they are mid range cards.

can anyone help me about origin and titanfall beta?
i was downloading the beta and i get a download speed of 50KBps.
but origin has a glitch and is showing 400KBps.
while it is showing 400KBps, it should download at the rate of 50KBps (since thats what my isp provides)
instead, it downloading 1gb in 30 minutes.(takes 6 hours on 50KBps)

are the servers of origin forcing my isp to give 400KBps or what?
if after downloading at 400KBps, it shows some error, then it is some origin glitch (and i would feel really bad)
but if this is really happening, then can someone explain to me the reason behind this?

Nvidia solidifies their dominance as the leaders of GPU technology once again! First Gsync, now this!
Not that AMD with Radeon graphics are worthless or anything, I'm not a fukin fanboy. Radeon cards can have some amazing price to performance ratios (like the 7770)
But, have to admit, Nvidias cards are technically superior, have many unique features, and are more powerful.

Neither of those won't be better or faster then 650 Ti Boost Edition, I assume according to this 750 will be on lvl with 7770 and 750 Ti will be faster then 7790 and 260X. But they are not superior, the Gsync is worthless cuz you need to buy a monitor that supports it which already costs much. Both make great GFX it's just what you prefer Red or Green and what you can afford.

Actually, not sure what you got from the acticle, but these maxwell cores will be quite a bit more powerful than kepler cores like 650 ti boost uses, about 135% more powerful. So 640 maxwell cores should be able to match or surpass 768 kepler cores easily. So 640 maxwell should equal about 864 kepler cores, unless I'm doing the math totally wrong lol.

And yes, both AMD and Nvidia make fine quality gfx cards, it's not like any (or many at least idk) are inherently "crapy" or anything. But, when comparing cards of the same level (technical level not price range), Nvidia cards more often than not come out on top. But that doesn't mean AND cards "suck" or whatever fanboyish crap one could sa

Yeah those characters limits.
Basically you got yourself an GTX 780 card and a standard FHD monitor, your GFX supports G-Sync but you won't be able to use G-Sync cuz your monitor does not support it, so you will need to buy new monitor with G-Sync support which are expansive. That's what I'm talking about.

Well, I maybe not much caring about Power Efficiency. I am sitting mouth-open looking at the performance jump. I would expect those two cards to have similar prices to their predecessors. Sadly, I've got to wait until a word is stated about a GTX 870 or whatever Maxwell GPU to replace the fascinating GTX 770. I should be getting a GTX 770 soon, I just wish I can wait for a Maxwell successor.
