At last quater 2009 Nvidia has announce and releasing new GPU core at new line 40nm process production. At least they will released 40nm from shrinking GT200 based like GTX260M, GTS250M, GT 240M, GT230M and GT210M for notebook segment, what they bring for desktop ? until now Nvidia have 3 GPU core based for desktop platform are GT210, GT220 and GT240 that will replace Geforce 9400GT, 9500GT and top midrange 2008 Geforce 9600GT. The good news are they 40nm GPU will supporting with Microsoft API DirectX 10.1 that introduce the first time by ATI 4000 series lineup.

The GT220 will sporting with 48 SPU or better than 32 SPU by Geforce 9500GT but with the same 128bit memory interface. Above the sheet performance GT220 in beetwen 9500GT and Radeon HD 4670.  You can see the different spesification and performance from the chart below

All Nvidia 40nm GPU equip with new decode video API VP4 acceleration while decoding MPEG4 ASP codec. as you can read my previus article about nvidia decode video acceleration for UNIX (Vdpau). While we all waiting for new GPU from GT400 based that will landed a few month again, Nvidia starting for delevering technology movement with better and cheaper cost production.The 40nm process does allow a rather low TDP and you can overclock it handsomely. Of course any attempts at passing these off as gaming cards will provoke gales of laughter.

The first 40nm GPU with DX 10.1 supported.

3 connectivity, analog, hdmi and dvi

Under the hood with GT216 core

from what i know, hynix gdd3 not much give headroom for oc

gpu cooler only using radial alumunium design

make coffee and sit relax for performance test after this…

For this baby i testing with only in  directX 9.0 API in windows XP SP3 cause i don’t want arguing for DX10/10.1 will boosting performance with entry level card. 1280×960 or 1280×1024 is the best resolution for these card if you still using 17″ monitor cause you still have headroom (FPS)  for tweaking graphics quality setting likes anti aliasing (AA) or anistrophic filtering. For gaming test all using 1280×960 resolution with high setting for SF4 and RE5, except mainstream mode for Crysis Warhead and default mode for STCS benchmark.

In anti aliasing performance we can see the huge penalty with 8x AA in Streetfighter 4 game that more than 50% FPS drop, i bet the best setting you can play with 4x AA or No AA up to 1680×1050 resolution. Don’t be mad cause not too ashame for sub $70 card

Overclocking test doing well with MSI After burner 1.5 tools that give such high headroom with core clock and shader clock. I ended up stable for benchmark test with 785Mhz geometry core and 1700Mhz shader core or about 25% performance gain. The Hynix gddr3 has failed to give more huge jump bandwidth data performance for supply to the GPU, i end up to 825Mhz gddr3 for stable performance. I know the result was vary your milestone maybe higher or lower

For noise and temperature, i measuring that 6cm reference fan blade from colorfull GT220 come with moderate tolerance noise level but unfortunetely the pwm of fan only using 2 cable without pwm sensors  or adjusting capabilities from driver.  The GPU consume about 58W of power at full load even test the GPU core temperature is around 72^c – 74^c and idle state at 50^c – 52^c with my ambient case around 28^c

Conclusion

[+] 40nm process production with complete dx 10.1 support and VP4

[+] It’s a cheap card for supporting windows Vista or 7 with only using 58w of power

[-] Lack of clock state for saving power even in idle.
