well, basically my question is just like the topic:

anyone still knows the existence of Physx card?
i do ha, for those who knows about it and live in Malaysia:

is there still Physx card selling in Malaysia? especially in Low Yat, 3 out of 5 shops don't know what's that what the heck man?

Physx card: if u buy a new nvidia card the Physx software technology come included in the new cards, dun need buy Physx only if u got a old vga under nvidia 8 series or ati radeon X1 series

yes indeed but the performance is not as good as a standalone Physx card...right?

if u got a cpu dual core u can emulate Physx softhware olso the lastesr video cards got fast VRAM,
tats means got better perfomance, Physx card its old tecnology

i know it's old but it can really work on your gaming rig
see, i don't want my CPU to process and render cause i want my CPU to focus on the ai more
take gtx295 stack with Physx can le

NVIDIA GeForce GTX 295 Specifications Unveiled
Thursday, December 18, 2008 - by Marco Chiappetta
Although we can't disclose all of the details regarding NVIDIA's upcoming dual-GPU powered GeForce GTX 295 just yet, we do have some juicy information regarding the card and its proposed specifications that we can share with you today.

We all knew that NVIDIA wasn't sitting idle since the initial release of AMD's popular ATI Radeon HD 4800 series of products. As today's information will show, it turns out NVIDIA was not only hard at work on a 55nm version of their GT200 GPU, but they have also designed a dual-GPU beast built around two of them. There is a bit more to the story though, as the specification will reveal.


Fabrication Process--------- 55 nm
Core Clock (texture and ROP units)---------- 576 MHz
Shader Clock (Stream Processors)----------- 1242 MHz
Memory Clock (Clock rate / Data rate)------ 1000 MHz / 2000 MHz
Total Video Memory---------------------------- 1792 MB
Memory Interface------------------------------- 448-bit per GPU
Total Memory Bandwidth ---------------------- 224 GB/s
Processor Cores--------------------------------- 480
ROP Units---------------------------------------- 28
Texture Filtering Units------------------------- 160
Texture Filtering Rate-------------------------- 92.2 GigaTexels/sec
Connectors--------------------------------------- 2 x Dual-Link DVI-I 1 x HDMI
RAMDACs----------------------------------------- 400 MHz
Bus Technology---------------------------------- PCI Express 2.0
Form Factor-------------------------------------- Dual Slot
Power Connectors ---------------------------- 1 x 6-pin 1 x 8-pin
Max Board Power (TDP)----------------------- 289 watts

As you can see, the GPU used on the GeForce GTX 295 is built using a 55nm manufacturing process and the reference specifications call for 576MHz core, 1.24GHz shader, and 2GHz (1GHz DDR) memory clock frequencies. What's more interesting is that each GPU on the GeForce GTX 295 is outfitted with 240 stream processor cores--for a total of 480--but the memory interface is 448-bits per GPU and it's got 28 ROP units, not 512-bits and 32 ROP units like the current GeForce GTX 280. The specifications reveal that the GPU used on the GeForce GTX 295 will be sort of a die-shrunk hybrid of the current GeForce GTX 260 and GTX 280. Max board power is rated for 289 watts, which is right on par with the Radeon HD 4870 X2 and, as such, the GTX 295 requires both 6-pin and 8-pin supplemental PCI Express power connectors.



NVIDIA GeForce GTX 295

The card itself is reminiscent of the dual-GPU powered GeForce 9800 GX2. There is a perforated shroud that surrounds the entire PCB, with an air inlet at one end near the barrel type fan. The fan pulls air into the interior of the card, where it is blown across heatsinks and then ultimately expelled from the system through vents in the card's case bracket. Outputs on the GeForce GTX 295 consist of a pair of dual-link DVI outputs and an HDMI output, but the pictures also reveal a couple of diagnostic LEDs. One of the LEDs indicates whether or not the board is receiving sufficient power and the other shows whether or not a monitor is properly connected and being detected.

Just in case you're wondering, yes, two of these cards can be run in tandem in a Quad-SLI configuration. And we should also note that a single card can even be configured to run with one of its GPUs dedicated to PhysX calculations while the other handles graphics. We're hoping to have cards in-house very soon and will be able to disclose more information in the not too distant future. For now, you'll just have to be content with some specifications and pictures. Performance, pricing, and technical details will be coming a bit later.

Ageia's PhysX physics processing unit
Smithereens gone wild
by Scott Wasson

I'VE HAD THE CHANCE to spend a few days playing with a PhysX card from Ageia, and there is much to tell, though not much one can do with the hardware just yet. I did find some interesting ways to test the PhysX card, and the results may enlighten us about the prospects for physics acceleration in custom hardware. Read on to get my take on Ageia's new physics processing unit.

The hardware
The PhysX card itself looks an awful lot like a video card, with its centrally located cooler and four-pin Molex aux-power connector, but don't be fooled. This card's metal slot cover is devoid of outputs, and the golden fingers extending from the board are intended to slip into a humble 32-bit PCI slot. This card is made for crunching numbers, not driving a display.



A pair of Ageia partners, Asus and BFG Tech, have brought PhysX cards to market. The board you see above is the BFG Tech version, and it comes with 128MB of Samsung GDDR3 memory chips attached. These chips run at an effective data rate of 733MHz on a 128-bit interface, which works out to 12 GB/s of memory bandwidth dedicated solely to physics processing.

Pop the cooler off of the card, and you'll find the star of the show, the PhysX chip, residing below.



This custom-designed physics processor measures roughly 14 mm by 14 mm, or 196 mm2. TSMC packs about 125 million transistors into this space when it fabricates the chip using its 130 nm manufacturing process.

The itty little rectangular chip you see situated below the PhysX PPU, by the way, is not a bridge chip like you might see on some PCI cards these days. This chip comes from Texas Instruments and is used to step down the voltage coming in from the PCI bus. As a low-voltage 130 nm device, the PPU probably needs its assistance in talking to the relatively high-voltage PCI bus.
