With DX10's arrival, vertex and pixel shaders maintained a large level of common function, so moving to a unified shader arch eliminated a lot of unnecessary duplication of processing blocks. The first GPU to utilize this architecture was Nvidia's iconic G80.
Four years in development and $475 million produced a 681 million-transistor, 484mm² behemoth -- first as the 8800 GTX flagship and then with cards aimed at several segments. Aided by the new Coverage Sample anti-aliasing (CSAA) algorithm, Nvidia saw its GTX demolish every single competitor in outright performance.
With the turn of the century the graphics industry bore witness to further consolidation. Where 3dfx was once a byword for raw performance, its strengths before its dismissal laid in its full screen antialiasing image quality. By the time 2001 dawned, the PC graphics market consisted of a discrete card duopoly (Nvidia and ATI), with both of them in addition to Intel supplying the vast majority of integrated graphics chipsets.
Prior to the Voodoo 5’s arrival, ATI had announced the Radeon DDR as “the most powerful graphics processor ever designed for desktop PCs.” Previews of the card had already gone public on April 25, and only twenty-four hours later Nvidia countered with the announcement of the GeForce 2 GTS (GigaTexel Shader).
Launched on November 1996, 3Dfx's Voodoo graphics consisted of a 3D-only card that required a VGA cable pass-through from a separate 2D card to the Voodoo, which then connected to the display. Voodoo Graphics revolutionized personal computer graphics nearly overnight and rendered many other designs obsolete, including a vast swathe of 2D-only graphics producers.
The 3D landscape in 1996 favoured S3 with around 50% of the market. That was to change soon, however. It was estimated that 3Dfx accounted for 80-85% of the 3D accelerator market during the heyday of Voodoo’s reign. Later on Nvidia would revive with the RIVA series and eventually land their greatest success with the first GeForce graphics card.
The evolution of the modern graphics processor begins with the introduction of the first 3D add-in cards in 1995, followed by the widespread adoption of the 32-bit operating systems and the affordable personal computer.
While 3D graphics turned a fairly dull PC industry into a light and magic show, they owe their existence to generations of innovative endeavour. Over the next few weeks we'll be taking an extensive look at the history of the GPU, going from the early days of 3D consumer graphics, to the 3Dfx Voodoo game-changer, the industry's consolidation at the turn of the century, and today's modern GPGPU.
Normally when we benchmark a first person shooter, finding a good portion of the game to test with is simply a matter of playing through the game until we find a section that is rather demanding. But with SimCity things were considerably more complex and time consuming.
A city with few sims will see graphics cards such as the GeForce Titan or GTX 680 render massive frame rates because they are not being capped by the CPU (yet). As with most simulation and strategy games, SimCity is CPU dependent and overclocking should result in a healthy boost if needed. More inside.
If you're planning on upgrading to Intel's Haswell platform later this year, you may want to wait for the first round of chips to clear shelves before taking the plunge. Hardware.info claims to have spoken with a "reliable source" who says the next-generation processors have a small issue with USB 3.0...
Crytek has given us another opportunity to hammer some hardware with the arrival of Crysis 3. Built with CryEngine 3, the engine has been updated with improved dynamic cloth and vegetation, better lighting and shadows, and plenty more.
Plus, PC gamers won't have to wait for graphical extras. Crysis 3 launched with high-resolution textures, DX11 support and plenty of customization options that set it apart from the diluted consoles builds. The result looks incredible and we get the feeling this will prove to be the game that folks who are heavily invested in multi-GPU setups have been waiting for. Here's hoping we aren't woefully disappointed.
