NVIDIA’s GeForce GT 220: 40nm and DX10.1 for the Low-End

Temperature & Noise
At idle, the GT 220 is one cool card. We’re a bit surprised that it couldn’t beat the 5850 here given the tiny 7W idle power usage, but the 5850 has the advantage of getting to vent hot air out the rear of the card.
Meanwhile we see one of the few chinks in the armor of the Radeon HD 4670. It idles a good 9C higher.
Small cards make little heat. Even with the small cooler on the GT 220, it doesn’t pass 79C. This becomes all the more impressive when we look at the noise data. Meanwhile the 4670 hits 90C. It may be the faster card, but it pays for it here.
Here we run up against the practical noise floor of our testing rig. Nothing with a fan can get below 46dB.
With a fixed speed fan, the GT 220 makes the same amount of noise at idle and at load. This means it’s still running into our noise floor under load even though it’s an actively cooled card. It has all the makings of a good HTPC card, if only the price-to-performance ratio was a bit better.
As for the 4670, it comes in at #2 with 50.1dB under load, making it noisier than the GT 220 but quieter than any of our usual suspects on the high-end.

Last week I bought a Medion P6620 laptop. It's fitted with an Nvidia 220M graphics card with 512MB of GDDR3 ram. The blurb of the box said it was a DirectX 10.1 card. Have NV released any details about the laptop 220M as well as the desktop 220? All I could find out from Wikipedia & Notebookcheck.net was that the 220M was a 40 micron version of the 9600M GT but the Anandtech review suggests that things are more complicated than this.My only contribution to the debate is that I picked up this laptop for a paltry £399. Given that my machine has a T6500, 320GB HD, all I can think is that NV has be giving away the 220M to OEMs for pennies!
Finally, has anyone seen any signs of Windows 7 drivers for the 220M? I got a freebie upgrade but I'm a bit scared of using it just in case there were no drivers for a graphics card that NV don't recognise on their own website.

I'm assuming http://www.nvidia.com/object/notebook_winvista_win...">these won't work? I know they don't list 220M, but they're the latest official drivers from NVIDIA; otherwise you're stuck with whatever the notebook manufacturer has delivered. I'd guess NVIDIA will have updated mobile notebook reference drivers relatively soon, though, to coincide with the official Win7 launch.Joe90 - Tuesday, October 13, 2009 - link
Many thanks for the link. I think you're right. Although this NV driver page refers to the '200 series', it doesn't explicitly mention the 220M card. Until it does, I'll hang back from doing the Windows 7 upgrade.As it happens, I've only just made the leap from XP to Vista. Despite all the bad stuff I've read, Vista seems ok so I might just stick with it for a while. I'm finding I can play games ok with the Vista/220M combination. I'm currently playing FEAR 2 at 1366 x 768 with all the detail settings on maximum and the game plays fine. Given the low price of the laptop, I'm more than happy with the graphics performance.

I've never had a true hate for Vista, but there are areas I dislike (several clicks just to get to resolution adjustment, for example). Windows 7 is better in pretty much every way as far as I can tell, although it's not like Vista is horrible and Win7 is awesome. It's more like Vista reached a state of being "good enough" and 7 addresses a few remaining flaws.Now, if someone at MS would fix the glitch where my laptop power settings keep resetting.... (Every few tests, my battery saving options will reset to "default" and turn screen saver, system sleep, etc. on after I explicitly disabled it for testing. Annoying!)

it's AMAZING for this gen's "lowest end" (at retail)... beats the pants off my 9400GT currently in my HTPC. probably even equals or betters my once only 2 generation old nearly high end HD3850.this is going in my HTPC in a heartbeat when it hits $30-35 (unless power consumption is stupid high, which i don't think it is. i THINK i read about this somewhere else, and someone was moaning about it using 4 watts more than some ATI part it was being compared to).

Given the more competitive desktop landscape, these new 40nm DX10.1 chips are not impressive at all. However, their mobile derivatives were announced months ago, and in the mobile space where mainstream GPUs seem to be made up of many, many combinations of nVidia's 32SP GPUs, a 40nm 48SP DX10.1 GPU would actually bring something to the table. It'd be great if we can get a review of a notebook with the GT 240M for instance.JarredWalton - Monday, October 12, 2009 - link
It looks like there are laptops with GT 240M starting at around $1100, and the jump from there to a 9800M card (96SPs, 256-bit RAM) is very small. Unless you can get GT 240M laptops for around $800, I don't see them being a big deal. Other factors could change my mind, though - battery life perhaps, or size/form factor considerations.apple3feet - Monday, October 12, 2009 - link
For some people, the most important detail of any new NVIDIA card is the CUDA Compute Capability. Will it run my scientific simulation code? Only if the CUDA Compute Capability is 1.3 - so that it supports double precision floating point arithmetic. Could we have just one line somewhere to tell us this vital info?jasperjones - Monday, October 12, 2009 - link
LOL,for dgemm (double-precision matrix multiplication) the GTX 285 is only about twice as fast as a Core i7 920 (using CUBLAS and Intel MKL, respectively).This suggests you shouldn't run your double precision code on a GT 220. Hell, even running CUDA code on your CPU using emulation might be faster than running on the GT 220..

You're wrong. Given the right problem, tackled using the right algorithm, and well-written code, TESLAs can do 20x the throughput of a Nehalem - even in double precision.
