Review: 20% (up to 30%) better than the last-gen mainstream 8600 GTS

 

Our today’s test subject is Galaxy's 9500 GT graphics card, and it’s based on an overclocked Nvidia G96 graphics processor. Compared to the previous generation this chip brings much better performance into the low-end segment. It’s supposed to replace G86 graphics processor and the cards based on it – Geforce 8400/8500.

Nvidia claims Geforce 9500 GT should be a hit card in entry level segment, bringing up to three times better performance compared to the previous generation, meaning Geforce 8500. This of course sounds nice, but 9500 GT will have to pack a punch in order to beat the cards in this segment (€65-80); HD 3850 and 9600 GSO to name a few but you can still find Geforce 8600 GT and GTS cards priced at around €45-60. It’s important to note that technical characteristics of G96 chip match those found on G84 chip on Geforce 8600 card (a mainstream graphics card), which means that 9500 GT has to prove it’s better if it is to sell well. Our Galaxy card runs at high 700MHz which is a first prerequisite to beat the 8600 GTS card running at 675MHz.

Reference Geforce 9500 GT card runs at 550MHz, the shaders at 1400MHz, whereas memory speeds depend on the design. Reference speeds of GDDR2 are 400MHz (800MHz effectively) while GDDR3 models feature memory running at 800MHz (1600MHz effectively). This makes it clear that reference 9500GT with GDDR3 memory are somewhere between GDDR3 cards: 8600 GT (540/1190/700 MHZ) and 8600 GTS (675/1450/1000 MHz).

The following picture shows Geforce 9500 GT; the one above shows Geforce 8600 GTS, and below it you see Geforce 8500 GT. Geforce 9500 GT even matches 8600 GTS length-wise.

Image
 
We’ve mentioned that technical characteristics of G96 and G84 cores match – 32 shader units with 16 texture units, 8 ROPs, but in both cases we’re talking about 128-bit memory interface. The new 55nm process brought about many improvements and this card should easily lock horns with the faster 8600 GTS card. Apart from that, there’s PCI Express 2.0 interface and PureVideoHD3/VP3 engine that make this card a nice treat in the low-end market segment.

Although the G96 on Galaxy Geforce 9500 GT card is built in 65nm, Nvidia is preparing 55nm 9500 GT versions that we’ll probably see as soon as they get rid of 65nm chip supplies. We don’t expect much improvement with this smaller chip, except maybe it’ll be less hot and maybe be more overclocking friendly, but we do expect it to be cheaper, which should help Geforce 9500 GT to stay in the run for the low-end title.

Geforce 8500 GT (G86 core) is definitely out of the game – the card uses GDDR2 memory, 16 shader units with 8 texture units and 8 ROPs, and it runs at 450/900/400MHz.

Image

Our test card, Galaxy Geforce 9500 GT, comes with overclocked GDDR3 memory running at 1000MHz and features a frame buffer of 512MB. This much memory is not standard in the low-end market, but it will definitely come in handy. The Shaders run at 1650MHz and the GPU at 700MHz. Taking into account that reference speeds are 550MHz, this card should perform much better.

Image

The following picture shows reference Nvidia Geforce 9500 GT card with a single slot cooler. You’ll notice that the biggest difference between Galaxy and reference card is the large cooler and PCI Express power connector not found on reference card. Nvidia claims that G96 will consume up to 75W (reference card is said to consume no more than 50W), and we put those claims to the test, testing Galaxy 9500 GT with no additional powering. The card ran stable and we even managed to overclock it further. By launching their juiced up 9500 GT card, Galaxy definitely pushed the low-end performance further.

Image

Image

Galaxy opted for in-house cooler design. This is a large dual-slot cooler with an 8mm heatpipe that runs silently, and it would probably do well on some even more powerful cards.

Image

The following picture clearly shows that this is a card that will take up two slots on your motherboard, but since silent operation is more important most of the time – we’ll let that slide.

Image

Among 9500 GT cards, there are versions with standard TV-out, D-sub and DVI port with HDCP support and HDMI (through the dongle), but if you want to route sound in the same cable you should decide on a card with an S/PDIF in. Galaxy’s card has one and it’s located left to the SLI connector. DisplayPort is still an option, but we’re yet to see someone implement it on 9500 GT.

Image

Galaxy 9500 GT card features one TV-out and two dual-link DVI ports with HDCP and 2560x1600 support.

9500 GT supports PhysX and CUDA (Badaboom software is currently the most famous). While most know what PhysX is, Badaboom is yet to be popular. This is currently the only app that managed to utilize CUDA-based approach and thus enable transcoding video content using GPU capabilities of parallel data processing.

Image

We put it to the test and it works, but we’ll leave comparisons to CPU transcoding to some later date when we see the final version of this software. Only a fraction of Badaboom app is currently usable and transcoding time is limited to about 2 minutes. The good thing is that MPEG2 content transcoding is quite fast and we managed to transcode a 2:40min video to iPhone-readable format .mp4 in 1:15min.

Image

Galaxy 9500 GT uses 512MB of Samsung’s GDDR3 memory running at 1000MHz (2000MHz effectively). Both sides of the card feature 4 modules and the memory has no special cooling.

Image

We mentioned that the cooler is extremely quiet, and during operation temperatures hit up to 43°C. This number quickly ducked to 33-34°C in idle mode.

Image

The box is quite appealing and it will definitely let you know that it contains an overclocked card.

Image

Xtreme Tuner is a tool for simple overclocking and you can find it on the installation CD. Even more so, you can use it to flash the card’s BIOS.

Image

We tried to overclock the card, but 800MHz proved to be too much, as we couldn’t finish the tests. After downclocking it to 770MHz, the card ran stable.

We used passively cooled Zotac Geforce 8500 GT running at default speeds and featuring 256MB of GDDR2 memory. We also used EVGA 8600 GTS running at reference speeds (675/1450/1000 MHz). This card features 256MB of GDDR3, but we’ll soon see that it can’t compete with Galaxy 9500 GT running at 700MHz and 512MB of GDDR3 running at 1000MHz. Galaxy card’s shaders run at 1650MHz, which is 200MHz more than Geforce 8600 GTS offers.

Futuremarks

Image

Galaxy Geforce 9500 GT results are good; but bear in mind that we tested the card overclocked to 700MHz, whereas reference 9500 GT cards run at 550MHz. These tests proved to be quite realistic in evaluating the power of the cards and gaming tests had pretty much the same results. Geforce 8500 GT couldn’t finish Vantage Test (Performance Level) and we received a message to lower our settings.

Gaming

Image 

We played Company of Heroes with “medium” detail settings and our gaming experience was good. We even managed to squeeze out a playable 27.4 fps at 1280x1024 and Antialiasing and Aniso filter on – something that not even Geforce 8600 GTS could do. 8500 GT lacks power and at medium settings we experienced constant glitches and stutters.

We lowered detail settings to “low”, and lo and behold – 8500 GT scored no less than 113.9 fps, or 76.5 fps at 1280x1024. Still, although gaming is possible, if you want to experience your games “the way they’re meant to be experienced” you should probably go with a more powerful card.

Image

In Company of Heroes, Galaxy 9500 GT scores up to 25% better than Geforce 8600 GTS.

Image

In Unreal Tournament 3, Galaxy 9500 GT beats Geforce 8600 GTS by about 14%. At 1024x768, it outperforms Geforce 8500 GT by 60 frames and at 1280x1024 by 42 frames.

Image

Geforce 8600 GTS again loses to Galaxy 9500 GT by 20% at all the tested resolutions. Overclocking made sure that Galaxy emerges a winner and it fulfilled Nvidia’s “prophecy” that this card will perform three times better compared to Geforce 8500GT.

We see a similar result in F.E.A.R., too.

Image

Image

Geforce 8500 GT didn’t make the grade in our DX10 gaming tests, among which you’ll find Crysis. It’s unlikely that you’ll be playing new games with this card, but that’s where Galaxy 9500 GT comes in. Galaxy 9500 GT scores nicely in Crysis but we must note that we lowered the detail settings to minimum. Still, 39 frames at 1280x1024 in a game like Crysis is good enough to brag about.

We tried gaming with “medium” detail settings at 1280x1024 but that didn’t go that well. Still, the result confirms that Galaxy 9500 GT is about 20% better than 8600 GTS.

Image

We played World in Conflict in DX9 mode, and Galaxy managed to beat 8600 GTS by up to 27% at 1280x1024 4xAA/8xAF. We didn’t manage to do the same with 8500 GT, so we lowered the detail settings to minimum. That did the trick so we got a playable framerate but with lousy graphics.

Image

We tried to turn on Antialiasing on 8500 GT using medium detail settings, but that didn’t go well. We received the following warning.

Conclusion

Geforce 9500 GT is a new low-end chip that Nvidia is using to try and snatch up a piece of the market before ATI RV 730 hits the market sometime in September. G96 chip (9500 GT core) comes as 8400/8500 replacement, but 9500 GT easily beats 8600 GTS as well; well, the overclocked card at least. Today we say goodbye to Geforce 8500 GT card, that’s no longer interesting now that we have 9500 GT.

Galaxy did a great thing by overclocking the 9500 GT to 700MHz, as it wouldn’t have done so well at reference speed (550MHz). The memory runs at 1000MHz which is 200MHz more than reference 9500 GT. Furthermore, the card packs 512MB of GDDR3 memory, which helps the core in overclocking and performing difficult tasks.

The only downside to the cooler is that it’s dual slot, but Galaxy in turn provides one of the most silent coolers we’ve ever seen (or heard). Compared to the previous generation, the low-end market segment now features a card with PCIe 2.0 interface and PureVideo VP3 engine that will help in HD video viewing and processing. The card is HDTV ready, whereas HDMI can be done through the DVI-to-HDMI dongle. CUDA and PhysX implementation are a novelty, and those will soon be featured on all Geforce cards of 8th and 9th generation.

This card will be sufficient for gaming, but don’t expect too much. We’ve seen that it performs better than Geforce 8600 GTS, a card that was one year ago a mainstream card, which further paints a picture of what Galaxy 9500 GT is capable of.

If the price doesn’t go higher than 8600 GTS’ current price of €45-65 this card might end up being a popular low-end product. In such a scenario replacing your 8500 GT with 9500 GT will be a good choice.

Galaxy 9500 GT is an overclocked card that we sincerely recommend if you running on a tight budget and it’s quite possibly the best low-end card made so far. Of course, the overclocked card will probably cost more, but we’re hoping it won’t be much more. Nvidia's 9500 GT is a great card, and Galaxy's overclocked version is excellent. However, it doesn't get our Recommended award. Performance-wise, it deserves it, but at current prices 9500 GT cards are no bargain.
