Xtasy GeForce4 Ti 4400 & 4600

To get an overall idea where the GeForce 4 videocards are compared from the entire new line-up I suggest you take a look at the following table:

  MX 420 MX 440 MX 460 Ti 4200 Ti 4400 Ti 4600
Number of Transistors (Millions) 29 29 29 63 63 63
Manufacturing Process (microns) .15 .15 .15 .15 .15 .15
Rendering Pipelines 2 2 2 4 4 4

Bandwidth (GB/s) 2.66 6.4 8.8 8.0 8.8 10.4

The new features, read keywords you need to remember, for the GeForce4 Titanium / NV 25 are Accuview, nView, nfiniteFX II Vertex Shaders, nfiniteFX II Pixel Shaders and Lightspeed Memory Architecture II. Let us look at some innovations and specs of the GeForce4 Ti series with you as provided by NVIDIA:

  • 63 million transistors (3 million more than GeForce3)
  • Manufactured in TSMC's .15 µ process
  • Chip clock 225 - 300 MHz
  • Memory clock 500 - 650 MHz
  • Memory bandwidth 8,000 - 10,400 MB/s
  • TnL Performance of 75 - 100 million vertices/s
  • 128 MB frame buffer by default
  • nfiniteFX II engine
  • Accuview Anti Aliasing
  • Light Speed Memory Architecture II
  • nView

When I fired up SiSoft's Sandra I started to check some videocard device settings and noticed that the Ti 4600 was based on the newer A3 revision/stepping while the ti 4400 had a A2 stepping. NVIDIA has moved the stepping to A3 recently, so it's likely that newer boards will overclock a tad better then this one. Stepping by the way is a newer 'build/revision' of the chip.

Xtasy GeForce4 Ti 4600

As you can notice yourself, the GeForce4 Ti 4600 uses the new A3 silicon. A3 clocks higher and therefore it makes sense that the  GeForce4 Ti 4600 uses it. I believe that revision A2 maxes out at a core clockspeed of ~310 MHz so it makes even more sense to use that silicon on GeForce4 the Ti 4400 and 4200.
