Nvidia GTX460 1gb (desktop) vs Nvidia GT 750m GDDR5 2GB (laptop)

Hi, kind of new to techy stuff like this. Hope someone can tell me how these compare to each other.

Things I've been told but am not sure are true.

1. X in GTX = MUCH better version of the GT version
2. Mobile is much weaker than desktop graphics of the same model
3. However, desktop has to display to larger screen, while laptops usually much less. (such as in my case)

I have the 460 on my desktop displaying to a 23 inch gaming monitor. I've been told that the bigger the monitor, the more the graphics card has to work. I also recently recently bought a Lenovo laptop with the 750m. Lenovo comes with an ultrabay to insert another graphics card to do something called SLI... which I think is just..using two graphics card instead of 1, obviously better.

I checked on videocardbenchmark and indeed the 750m is a bit below the performance of my old gtx 460.

So my question is...with all this in mind, gtx 460 for 23 inch 1080p gaming monitor vs a gt 750m for a 15.6 inch gaming laptop, how much weaker performance am I going to get?

 

GTX460 desktop is around same performance as GTX670m, so your GT750m is really close...maybe 10% slower...

Nothing to worry about, you can still oc that 750m to match GTX460.

 

I'm still confused about this OC stuff. Would a metaphor to help me understand be...it's like turboing your car? Increased performance...more stress on card, gets hotter, shorter life? Otherwise, I'm not sure why all cards don't come OCed

 

Every card is different. You take your chance and try to push it further, increasing your clocks little by little while you monitor your temps.

You can always check some guides how to begin overclocking, there is many for your card. Free performance? Why not....

 

The graphics card has to work harder the higher the resolution, the size of the monitor does not matter, whether its a 17 inch 1920 1080 or a 27 inch 1920x 1080. Both of your screens will most likley be 1920x 1080 resolution and the 460 desktop card is better than a 750m and the desktop card will be approx 20 percent faster due to the gpu being faster and having a higher memory bus, 256 ( or 192 i believe) vs 128 bit.

 

Alright. The reason I thought the gt 750m was better was because all I read was 2gb > 1gb.

What are the stats I should look for and what do the numbers mean? Please explain this to me like I'm 10 so I know how to shop for graphics card in the future.

GB = max amount of memory, but what does that do?

What are the other specs, memory speed, core speed, etc and what are "staples" for decent gaming. By staple I mean like...how 8gb of ram seems to be the staple nowadays for minimum ram to be comfortable on gaming computers.

 

Memory is only one factor that affects video card performance. There are many factors as you noted. So many that you can't just look at card specs and know for sure which is right for you. Some are easier than others based on specs. Instead I advise you to look at benchmarks. Find some cards in your budget, then see how well they run games that you might play.

I say to check benchmarks for games you play because everyone plays different games. And what you considure decent will be different than what I considure decent.

As to why not all cards are over clocked, well you have to understand that each card is different. So if you had two 750Ms, one will be capable of slightly better performance. The manufacturer ships them at a performance that all of them can handle without problems. When you over clock you increase performance, but you increase heat and increase the chance the card will lock up or start having glitches.

Sometimes the card can't be over clocked because the manufacturer wants you to buy a more expensive card.

I hope that makes sense.

Lastly, what was said about resolution and display size was correct. So a graphics card driving a 17 inch monitor will work just as hard as one driving a 23 inch monitor, assuming they have the same resolution and the game is running with that resolution. So if they are both 1920x1080, which they might be, then they are the same load to the graphics card.

But while there is a good chance they both are 1920x1080, one could have have more or less resolution. But what is important is that the more resolution the more work for the card. And your monitor, even though it is 1920x1080, it should be able to run your game at lower resolution. So maybe you have a game that is unplayable at 1920x1080, it might play great at 1024x768 as that is way less work for the card. Of course the game will not be as sharp, kind of like going from standard def tv to HD tv. But it is one way to get more performance out of an aging video card.

 

750m will be severely limited in higher resolutions due to the 128-bit bus and the 460 will likely outperform it considering it has either a 192-bit or 256-bit bus depending on which version you have.

 

Here is a review of the Lenovo Y510p with two 750m cards in SLI mode, which means the split the work. Review Lenovo IdeaPad Y510p Notebook - NotebookCheck.net Reviews

SLI tends to double performance in most games. But it can produce something called tearing, which makes the display look briefly, and slightly torn while updating. I don't have SLI but I think tearing would drive me nuts.

I couldn't find a review for the Y500p with 750m as it must be too new. I can post the notebookcheck one of the Y500p with 650m if you like.

 

Thanks for all the help guys.

Got a couple more points/questions.

1) Severely limited eh? Guess I might take out the dvd drive and put in another identical graphics card. That is what SLI is right? I should clarify I already bought the Y510p with the 750m. I haven't gotten around to even turning it on yet and playing games on it. Was just curious about how to know specs when shopping for graphics card in the future.

2) 128-bit bus? 192? I'm guessing higher number the better here as well? So how do you guys think skyrim will do on this single 750m. If not it's not too expensive to just buy another gt 750m? Or instead of SLI, should I just buy one good mobile graphics card? Friend told me one good one is better than two medium ones doing the performance of one good one. Most graphics card are one size fits all?

3) Also why i'm asking about graphics card, gf buying a sony vaio ultrabook. I7 8gb ram 128 ssd, but integrated graphics (HD Intel Graphics 4400). How bad is that going to be for gaming? We might be getting elder scrolls mmo. Will it be terrible on the sony?

4) Learnt a new term...switching. Apparently all processors have integrated graphics and computers with both discrete and integrated graphics will use one or the other?. Is the lenovo just wasting the one in the I7? Or do these laptops know when to use which.

 

Well very few laptops let you upgrade the GPU. The Y510p lets you use an identical one in the optical bay for SLI, but that's your only expansion option, and a unique laptop because no others offer that.

The bus refers to the memory bandwidth. Yes higher the better, but so far maximum is 256-bit for mobile GPU's and it's only found on the higher end cards. In theory you should be able to offset the limitation by running your video RAM at much higher speeds. Most laptops house a 128-bit or 192-bit. 192-bit is really what you want for 1920x1080 resolution gaming for current generation games and going forward. SLI should help because it effectively splits the scene each card is rendering in half, so each card is more or less rendering 960x1080 image than the full 1920x1080.

Furthermore, depending on the GPU, the 750m and below are soldered on the motherboard, they cannot be removed or replaced, well except for the odd 750m SLI expansion in the Y410p/Y510p. IMHO a single card is always better that dual because it uses less power, less space, and less likely to cause issues. Not all games are well optimized for SLI either, so you may only get 50% performance boost using a second card, sometimes no boost.

Higher end notebooks have what are called "MXM" slots that they can swap out GPU's, similar to how you would in a desktop PC. But you typically need a specific card, and they aren't always compatible with future released cards. Plus the laptops tend to be bigger, heavier, and more power hungry.

Integrated graphics have come a long way, but they're still meager performers with games. They are really only good for 720p at low or if lucky medium settings. Future games are questionable if they will even play. It will likely handle Elder Scrolls MMO ok at 1280x720 at low/med, but I wouldn't expect miracles.

nVidia has Optimus which is in their drivers that allows the GPU to switch between integrated graphics on the CPU and the dedicated card. AMD has a similar feature called Enduro. The laptop also has to be wired to the integrated GPU for this to work. The Lenovo Y410p/Y510p uses Optimus with a single card only that I am aware of. With SLI you lose the Intel GPU switching ability.

 

I agree with what HTwingnut says, except when I looked at the current Y510P I found out it does not support Optimus and there is no way to enable it. The Y510p is a great value, and I thought serriously about getting one. But the lack of Optimus means that when you are surfing the internet or other non-gaming things the laptop will be using more power. Also the 750m in SLI gives very good performance and most popular games support SLI. But there are asmall handfull that do not support SLI, Company of Heros 2 is an example. Also, as I mentioned, with SLI there can be tearing. Oh, and since I am talking about the Y510p, I also didn't like the slow hard drive.

I know Skyrim is not one of the most graphically intense games out there. So middle level cards can handle it well, but not the built in Intel graphics. Looks like Elder Scrolls online will be playable on almost anything with a dedicated graphics card. The Elder Scrolls Online system requirements

Here is a good review on the HD 4400 that shows several games. Intel HD Graphics 4400 - NotebookCheck.net Tech

So from that Skyrim is playable on the HD 4400, but only just barely. You have to lower quality and resolution to do it, and then it just barely can do it. Looking at the review you can sed some other games are playable, others are not at all. Just look for a minimum of 30, which is frames per second. But the Elder Scroll Online should have lower system requirements, simular to WOW. So I would think it would do it. Since the game is not out yet, there is no way to be sure.

 

The GTX 460 is clearly the better GPU with its 256-bit memory bus. Compared to mobile GPU's it's around the level of a GTX 580M/675M/765M or a Radeon 6990M. Since the Y510p is 1080p like your desktop display your gaming performance will be worse on the laptop but if you upgrade to SLI then it will surpass it.

 

Actually no, 580M/675M/765M are GTX560-Ti level and 6990m is HD 6870 desktop.

GTX460 is more or less GTX670m.

 

I'm talking real-world performance, not numbers on a spec sheet. 580M and 675M have the same core as the GTX 560 Ti but are severely underclocked, same thing with 6990M and 6870. 765M is obviously limited by its 128-bit memory bus. So in real games 580M and 675M perform more like desktop 460 and 6990M performs more like desktop 6850.

Also, if you look at the spec sheet the 670M is obviously crippled compared to the 460:

GTX 670M
Core config: GF114 336:56:24
Core/shader/memory clocks: 598/1196/3000
VRAM: 1.5GB/3GB 192-bit GDDR5 @ 72 GB/s

GTX 460
Core config: GF104 336:56:32
Core/shader/memory clocks: 675/1350/3600
VRAM: 1GB/2GB 256-bit GDDR5 @ 115.2 GB/s

 

No, octiceps is the one who's right. The 670M (straight rebrand of the 570M) is nowhere near the GTX 460. The GTX 460 scores 14k in Vantage GPU, stock, while the 580M is in the 13k range. The 570M scores 10k.

The stock GTX 580M gets murdered by the 560 Ti. Badly, because it's like a 30% downclock..
