ATI Mobility Radeon HD 5870 vs. NVIDIA GeForce GTX 285M

The real benchmark should be 540M vs 620M, since all the 620M has is a slight bump in clock speed.

Anyone choosing the 620M is wasting money.

 

If any CPU offers only a slight bump in clock speed, it's the 540M. At least the 620M offers an extra MB of cache and extra Turbo Boost as well (hence the bump between the i5-540M and the i7-620M is more like 266MHz, as long as the maximum Turbo can be maintained).

 

Yeah kinda of a general statement that doesn't work.

You can overclock the latest AMD Phenom II X6 up to 4 ghz across ALL SIX CORES using stock air cooling.

 

But the cost difference from say the 520M to 540M vs. 520M to 620M is typically quite steep.

 

i totally agree..

well it doesn't have hyperthreading so i rather get one of those new k series from intel.. they look much better especially with hyperthreading.

 

There more differences between the 620 and 720 processors than just mere clockspeeds. The later having higher fsb, more cache and other things (I think it has an integrated memory controller?).

Due to that, the difference of 266+mhz (actually, i think it is 3ghz vs 2.4ghz) makes the 720m processor keep up despite being heavily underclcoked and perform similarly. Both processors end up performing very similar, and in most casual apps the 620m wins because of the clock speed difference, while in some others, the 720 wins (usually heavy threaded apps, and not all of them).

Additionally, being 2 cores vs 4 cores does have its impact. Activities are not always split up evenly either, just as some benefit by having more physical cores to have a snappier feel to multitasking.

In the end, now that we are able to OC CPUs, I dont care I have the slowest I7 right now. Besides, gamingwise, GPU will be the first bottleneck for now, as they are quite underpowered on notebooks so most users won't even benefit from high clock CPUs, usually.

 

The awesome thing about the new AMD Phenom 6 core, is that it performs closesely to the 4 core hyperthreading core i7, and has a bit lower price so you actually get quite good performance for the price.

The downside is that as far as I know, it is not as good in some games compared to even the previous 4 core phenom. But those benches I saw where very old, dunno about now.

 

Exactly. The price : performance skews heavily in favor of the 540M.

I'd pay +$100 for the 720QM before +$80 for the 620M.

 

In the case of the NP8690 we're discussing here, it's $50 vs $80, and if $50 is worth it for the 540M then $80 is even more worth it for the 620M.

In any case, price : performance skews heavily in favour of the i5-520M, and against the i5-540M and all the rest of them - considering that the i5-520M is a $225 CPU, $50 for +5% is ridiculous.

As for the i7-720QM, I'd like to see more benchmarks comparing it to the i7-620M, but what I've seen so far indicates that the i7-620M is the better choice, especially when it's cheaper.

 

my point exactly.. i rather pay slightly more for a quad rather than a pumped on drugs dual..

 

Ya know, you're right.

Either take the 520M, or the 720QM. Everything in between is a mistake.

 

actually the 5XXX series isnt a new architecture. The fermi is... >.< The 5XXX series is just a pimped out version of an older architecture with higher clock frequency more shaders etc, forgot which one (3XXX maybe? dont quote me tho lol) :/

 

are u one of those NVDIA fanboys? the 5000 series is actually completely new architecture and actually thrashes any NVDIA card out now.. officially , GTX480M isn't here yet... do u know that NVDIA is actually been selling pimped up versions of G92 for last 2-3 years... get ur facts right dude..

IMO ,

5870>>>> GTX285M..

 

yea i no >.> both nvidia and ati are great. I neva sed anythiong bad about ati, i just said that its not a new architecture...

Edit and yea i agree with sean get 5870m cause its got more pros than cons. the sager 8690 offers a 5870m at stock anyways so dont create more hassle for yourself

 

5870m is new architecture... If it wasn't then how did they get DX 11 into the 3xxx cards?

 

they obviosly made some changes... just cause its off an older architecture doesnt mean it has 2 b the same >.>
