well I should say laptop gpus arent the strongest(the 650m is maybe like a HD 7750 desktop gpu). Its better than most laptop gpus, but still isnt up there when it comes to performance comparing it to a desktop of course. the top 2 laptop gpus, 680 and 7970m barely reach the 7870 level(atm 260$ desktop gpu), thats telling you something

so what should i prefer a hd 7670 with core i5 3rd gen or a gt650m with core i5 3rd gen for hardcore gaming experience?


Mobile i5s are just mobile i3s with Turbo and maybe some more cache. It's not like desktop quad core i5s versus mere dual-core i3s.

If it's i5 plus GT 650M versus i5 plus Radeon 7670M, then the first option takes first place by far. If it's AMD A10 plus 7670M versus i5 plus GT 650M, the results are not so simple.

One thing to remember is that Kepler GPUs (GT640/650/GTX660) can and will be different in laptops.

Case in point; Asus GT650m's use GDDR3 which is usually speculated to perform 5-10% (or more) less than a comparable GT650M chip on GDDR5 memory such as the MacBook pro which uses a GT650M with GDDR5 memory.

On the other hand you get manufacturers that love to mess with the speeds of the chips , memory, and cooling which limits performance due to heat.

Dells and Hp's are notorious for getting hot under load. Sony's use a highly underclocked GT640MLE which is 20% worse than a normal GT640M. Sammy's use standard chips but iirc was reputed to also get a bit warm under load. Lenovos are also excellent; same with asus.

If you get a kelper GPU; remember this. Every single chip is identicle be it a GT640m/650m/GTX660m. All that's different is clock speeds; memory interface; and cooling solutions of which all affects the performance of a laptop.

If its samsung vs dell.. i'd take samsung. Would prefer an Asus or a Lenovo or custome ones like a Clevo / Sager

GDDR3 on a modern graphics card? I didn't know that they still use it at all. Can you give me a link to look into this? I tried a web search but didn't find anything.

some 7670m's and all 7730m are both GDDR3 cards as well as GT 620m/630m/640m as well as some GT 650m's. All modern graphics cards.

hell guys why are u arguing?i just need to figure out which is a better brand of laptop and what config is necessary for high or mid setting gaming????


No one was arguing and what went on is clear if you read the posts. We've already said what brands we think are the best. Unless you give us a budget, we can't recommend specific laptops to you.

Is that $1200 USD?

Also, I just looked at your profile and looked up "biratnagar"... Asia? If that's where you live, can you give links to online stores that you can buy from? I can recommend laptops, but I don't know if you'd actually be able to afford them because I don't know how your listed location affects cost compared to the USA's prices.

yeah blazorthon bro thats rite im from nepal a country that is least developed in electronics items,electronics items such as laptops and its parts are hard to find and if you find them hardly it will cost u around double the rate that is mentioned in the website.....and concerning the price and affording a laptop,i m looking from flipkart.com,the site provides free shipping across indian states and as my brother studies their there is no issue in getting them shipped

What do you think of this laptop:
http://www.flipkart.com/samsung-np355v5c-s03in-laptop-a...

7670 plus an A8-4500, it doesn't get much better than that. The GTX 650M would have similar performance, but the only laptop with that card from your linked website is almost twice as expensive, granted it does have an i7 CPU to justify the much higher cost as it's much faster than the AMD APU's CPU performance. The more expensive i7 laptop that I looked at is this model:

http://www.flipkart.com/dell-new-inspiron-17r-se-laptop...

The i7 laptop is around the top of your budget according to my currency calculator and the AMD laptop with similar graphics performance but inferior CPU performance is a little more than half of your budget according to the same calculator.

well i think my budget is around 52000 indian currency so how about i get this one please have a look,please mate help me with laptops as i ve never had one before,now i am looking to get one that worths every single penny of my money:
http://www.flipkart.com/samsung-np550p5c-s01
please help me if its a gaming system or does it sucks u can have a view at some more from flipkart.com and repost it after thinking whats right for my budget?
thanks buddy

The HP has an Intel CPU and a Radeon 7670M, so it is weaker than the Samsung laptop for gaming because the Samsung has the GT 650M. The laptops with a Radeon 7670M only have similar graphics performance when their CPU is an AMD A6 or A8 APU. The A6 and A8 APUs have decent GPUs built into them that can work with the Radeon 7670M to make a dual-GPU array that has similar graphics performance to the GT 650M.

The AMD laptop's performance per core on the CPU is a little low for modern gaming and many games might have problems with it. It offers similar graphics performance to the Intel laptop, but the CPU is weaker.

If you want to save money, then there are some tricks that you can do to really help the AMD's laptop's CPU performance, but no offense, you don't seem like the sort who likes dealing with advanced settings. The Intel laptop is the better way to go if you're willing to spend the extra money.

If you insist. There is a program called PS Check from AMD. It can be used to alter the P states of the CPU (power/frequency states). You could use it to cut down the second core of each module (four cores of a CPU are organized like this: Core 0, Core 1, Core 2, Core 3; You'd be cutting down Core 1 and Core 3's P states) and boost the first core significantly. It probably wouldn't be able to quite match the mobile Intel i3/i5 CPUs, but it would be plenty powerful enough for some decent gaming. This would give it a good boost in games except BF 3 MP. If the laptop also has BIOS control of settings such as the BLCK and the memory frequency (unlikely, but possible), then you could do a little more with some minor overclocking.

However, like I said, this is advanced. If you're sure that you want to do it, then you know what laptop to buy and you now know what you'd need to do to work with it properly. If you need help on using the program, then there are probably some online tutorials that you could follow and/or you could come back to the Tom's forums for more help.

http://www.xtremesystems.org/forums/showthread.php?276190-AMD-PSCHECK-for-Bulldozer-UPDATE-NEWER-VERSION-amp-INSTRUCTION-HOW-TO-USE-IT

That's PS Check and a quick guide on how to use it.

It's the program LN2 overclockers use to tweak their CPU's for maximum speed, it gives you a very large amount of control over your CPU's clock and voltage.

Modern CPU's actually have multiple clock / voltage settings, what's in the BIOS is just the default / maximum setting. If the CPU has an unlocked multiplier then you can not only set the maximum but also all the settings from the lowest (800Mhz) to the highest. A CPU's highest clock is often determined by it's temperature output (TDP), by underclocking unused cores you cause them to use less power / heat which free's up more power / heat for the core you do want to overclock. This is especially true for laptops which tend to have really bad thermal solutions, OEM's are cheap.

For the 7670 vs 650, it's a big game of "it depends". With generic DDR3 memory their both pretty much the same as their memory bandwidth starved. With GDDR5 the 650 pulls ahead by a good margin. Seeing as we're on a budget it might be a bit hard to find a good notebook with GDDR5 for it's GPU.

I used to be a big fan of the HP DV6/7z series but lately they've been making their notebooks without an internal dGPU and your stuck only using the iGPU. Of course their DV6/7t line (Intel CPUs) have dGPU's with them, so kinda puts me off that they would do that.

Differences in capacity beyond 1GB will not make a difference for these cards. 2GB isn't better than 1GB unless you go for a much faster card.

I missed where the GT 650 M in your laptop is only DDR3. The AMD laptop has better graphics performance than the GT 650M DDR3 in that Intel laptop has.

The Samsung laptop that I linked does exactly what you want to do, would let you get some somewhat hardcore experience with the computer's CPU (you seemed interested by that earlier), and would be far cheaper. It would seem to be the best option that you have from that website, so it's my recommendation, unless you want to look at other want sites too.

AMD's hybrid crossfire is just a marketing gimmick i have an asus k53ta and never use crossfire option it microstutters have too many bugs and drivers never get any mature as said if you have the choice gt650 ddr3 ddr5 both miles away better than 7670m + crossfire option

That's with a weaker APU and a weaker graphics card. I also have to ask what the driver version that you're using is and if you properly updated it by booting into safe mode, using Driver Fusion to completely delete the AMD graphics drivers or a similarly thorough method, and then restarting the computer and installing the newest driver version. Current drivers or this are quite mature, so you almost definitely didn't set it up properly. That you mistook GDDR5 for DDR5 does not help your case.

i didnt bothered to mention its graphic memory sure were talking about graphic cards

i tried every possible combination in the catalyst center to make crossfire benefitable but it was only a hassle. do you have a fusion lappy? have you ever tried messing options ?? im not the only one who think hybrid crossfire is a joke there many people on the net regret to buy those tech for believing that hybrid crossfire does make a difference but no hope. Just get the gt650m, if you go amd way you ll only be disappointed

The problem is probably that you have a weak CPU. Try using PSCheck as stated above to increase one core's performance while decreasing the other core's performance to see if it helps. The A8s and A10s are a lot better than the Trinity A6s. Dual Graphics does work when it is set up properly and the CPU isn't too weak.
