Here are the first pictures of a partner-branded GeForce GTX 750 graphics card taken apart. It reveals a couple of things - to begin with, the GM107 silicon will bring about some genuine performance per Watt improvements, despite being based on the existing 28 nm silicon fab process, and second, that cards based on the chip will be extremely cheap to build, giving NVIDIA a good chance to strengthen its position in the sub-$200 market segment. This particular card is cooled by a simple fan-heatsink that's essentially a chunk of metal with a fan latched on to it. The card relies on a simple 2+1 phase VRM, which draws power from a single 6-pin PCIe power connector. NVIDIA is expected to launch the GTX 750 and GTX 750 Ti a little later this month.

Waste of copper for a little extra real estate. Plus it helps these cards to fit into HTPC's with limited card length :) Though I do agree small cards look ugly.

If it was single slot it would have looked great. Dual slot cooling makes it look ugly and thick. And 6pin on the non TI one?

The fact that needs a 6 pin power connector eliminates most expectations about a super efficient maxwell architecture. There was a leaked preview that was saying about no 6pin power connector in either card, 750 and 750Ti. It seems that that was a false preview, a lie, maybe a paid article to create a little more hype about Maxwell.
I just lost almost all interest about Maxwell.

Sub $200? SUB $200!!!! Really? (go take a look at the GTS 450, or GT 640, (no 6 pin connector) or GTX 650 and what price those were at) Video cards are WAY over priced these days. Look at how simple the card is. If this comes out for more than $130, I'll throw a fit. :p I realize that time marches on, that the technology and performance increases, and that inflation happens (and the devaluing of the dollar), but today we have single GPU's selling for >$700. Go back to the HD 5870 when it was introduced, when it was top dog, and see how much it was going for.
If it was single slot it would have looked great. Dual slot cooling makes it look ugly and thick. And 6pin on the non TI one?
Single slot=noisy. Or are they trying to make it look more impressive?

Why because it doesn't consume 20w like you were hoping, and built up unrealistic expectations from reading "RUMORED" articles?

Nvidia give us back the high Shader clocks not that 65Mhz extra funny boost clocks
that's why a Fermi With a 384 cores easily beats a 768 cores on the kepler because each core on the Fermi has 2x computing power of the kepler . thanks to the shader clocks.
I Prefer performance over efficiency.

Exactly my understanding of the situation.

It seems that that was a false preview, a lie, maybe a paid article to create a little more hype about Maxwell.
The other side of that coin could be some non-reference SKUs will be fitted with a 6-pin connector (and likely some OTT proprietary cooler and oversized shroud) while the reference version will not...and for some reason, some people are pushing the PCI-E 6-pin as a design specification rather than an option.

It could be, but even if it really needs the extra power connector we will have to wait to see how much close will be to 75 Watts. A 750 NON Ti with 768 cores at, for example, 85W, is really good, it is just not as good as this was saying

A little info about price, if of course this end up correct.
Felbukkantak az érkező GTX 750 Ti modellek, jön a Radeon R9 280 és R7 265 | Tech2.hu
It looks like a price tag for 750Ti between 650Ti boost(before going EOL) and GTX660 if I am not mistaken(the prices exclude VAT).

Not to sound like a AMD fanboy but I just read about the rumored AMD R9 265 which looks better than this (specs/price weise) but nothing is certain.

. A 750 NON Ti with 768 cores at, for example, 85W, is really good, it is just not as good as this was saying
Two points:
1. If you're estimate that the 750 non-Ti eats 85W, how do you explain the Asus card not needing auxiliary power?
The naked PCB (from my earlier post that I linked to- and which seems to have been ignored)

The retail package

and,
2. I think it has been established that GK107 is 640 core/ 5 SMX / 128 core per SMX (information also noted in my earlier post, and publicized >>here<<)

For those complaining about the power consumption, remember that this is still on a 28nm node. Maxwell is likely only slightly more efficient than Kepler and the rumored low power consumption of cards is probably due to the expected 20nm process that most of the chips will be built on. Intel's Ivy Bridge brought the power consumption of desktop i5/i7 chips down from 95W to 77W compared to Sandy Bridge (23% reduction) but it needed a drop from 32nm to 22nm to do so. I wouldn't at all be surprised if we see the 750 and 750Ti show up later on with 20nm chips and no added PCIe power connectors as they would easily be the fastest cards on the market powered by the PCIe slot alone.

So you try to tell us that it will be worse than the gtx650/650ti both in performance and probably power too? Then why not just rebrand and profit? I still trust Wizzard over your claims from other websites that this is not a 640SP part. That would be a huge flop, lower shader count and less performance for the Ti, the other doesn't really matter as the regular GTX650 is junk. I can tolerate the 6pin on overclocked boards, or just for cleaner power and less strain on the pcie power delivery, as every PSU nowadays has at least one plug. I am sure that some manufecturers like the Asus above opt for cost saving. That PCB looks even more horrible than the one in the OP, it has place for much more components that are just left out to save money, and the 6pin location is damn awkvard, yet they will ask the same price and claim that it is an OC version.
Well.. 2 weeks or so till the (at least paper) launch. It will all become clear then.

1. I don't. It is just a hypothesis, nothing more.
I have seen that picture and the strange thing about this PCB is the upper left corner where someone can see something that looks like a 6 pin connector. An early engineering sample maybe with a strangely positioned power connector?

2. Established? Not really considering that all over the place specs where talking about a 768 cores 750 and a 960 cores 750Ti, WITH gpu-z screenshots. So, those screenshots where wrong? Then it seems that whatever we knew about these cards yesterday, it is false today.

With "only" 512 cores on 750, 75W isn't really something strange. 650 with 384 cores was a 64W card. A 512 cores card with a new optimized design a couple of years latter needing less or about 75W is just something normal I think. 750Ti with "only" 640 cores I could guess it will end up close to 90W?

I personally still guessing here, nothing more. Info about these cards changes rapidly day after day.

I still trust Wizzard over your claims from other websites that this is not a 640SP part. That would be a huge flop.
I haven't seen anywhere W1zz saying something about this card. On the other hand this is the successor of Kepler GK107, a part with 384SP which was used in the GTX650, a low performance desktop part but rather successful in the mobile variants. For the 650 Ti Nvidia used the GK106 which is a different beast altogether, fully enabled sporting 960 CC (768 for the 650Ti) and having more than twice as much power consumption and twice as fast as the GTX650. Now look at all these leaks and tell me what do you think about GM107? Compare with GK107 almost double SP, probably almost same power consumption, maybe 75% faster on the same 28nm. Ain't life sweet? Except Nvidia uses a cut down version for the 750 (one SMX disabled) and the full chip for the Ti so we won't see this huge performance increase (remember that the 650 Ti has a GK106).

I have seen that picture and the strange thing about this PCB is the upper left corner where someone can see something that looks like a 6 pin connector. An early engineering sample maybe with a strangely positioned power connector?
Well, the Asus card pictured in the second image tends to lean towards the card being retail rather than "an early engineering sample", and the solder points for the optional 6-pin auxiliary power are clearly visible....I would have thought.

They also said

VideoCardz.com said:
Gigabyte GTX 750 OC (GV-N750OC-1GI) is a 512 CUDA cores Maxwell graphics card. Some GTX 750 models are not equipped with power connectors, but since we are looking at factory-overclocked model, it does have one 6-pin power plug. The difference between GM107-400 and GM107-300 lays in the number of CUDAs and TMUs. The difference between GTX 750 Ti and GTX 750 is also in memory size. The GTX 750 has only 1GB by default. The rest is pretty much the same, although the clocks are slightly different — all GTX 750s have 400 MHz slower memory (5 GHz).


The ASUS 750 is OC model but does not need a 6pin but the Gigabyte does. Just adds to the confusion.

The PCB from OP looks more inline with the Gigabyte and not the ASUS one.



None look like the Asus.

I haven't really seen the ASUS picture carefully. When you are used to see a specific connector in a specific place you don't usually consider something totally different that also doesn't look logical to end up in a retail card. You think that this is just a unique case, an engineering part where strange positioning of stuff and sometimes wires are more common.
