NVIDIA GeForce 7800 GT Reviews Hit the Web. NVIDIA’s New High-End Graphics Processor Introduced

NVIDIA has released yet another high-end graphics processing unit, but at this time for enthusiasts with budget of about $449. The new product appeared to be pretty promising: modern architecture with support for new capabilities and up-to-date feature-set is accompanied by low power consumption and noticeable overclockability, which may help the chip to gain popularity among enthusiasts.

“NVIDIA’s GeForce 7800 GT conquers everything on the market right now, except the GeForce 7800 GTX of course, which makes it pretty obvious selection when choosing between products like the GeForce 6800 Ultra and the RADEON X850 XT PE,” states X-bit labs’ article.

NVIDIA’s GeForce 7800 GT features 20 pixel pipelines, 7 vertex pipelines and in virtually all benchmarks delivers higher speed when compared to the GeForce 6800 Ultra, the former top offering from NVIDIA. Numerous web-sites have reviewed the product and appeared to be pretty impressed.

“Looking back at the performance and image quality we experienced on the BFGTech GeForce 7800 GT OC, we are left with a big smile on our faces. Here is a video card that is $150 cheaper than a GeForce 7800 GTX and, in many games, it can match image quality with its more expensive sibling. In very GPU limited games, you typically just have to set the image quality down one level compared to the GTX. Putting two BFGTech 7800 GT OC video cards in an SLI configuration gives you the performance and image quality that matches two GeForce 7800 GTX in SLI,” summarized [H]ard|OCP web-site.

Intel’s Pentium 4 Overclocked to 7.1GHz, Sets World’s Record. Overclockers Set World’s Super PI Record with Prescott 2M at 7.1GHz

A Japanese overclocker has managed to overclock Intel Pentium 4 670 microprocessor to 7.132GHz and even run certain benchmarks on the system that was cooled down by liquid nitrogen.

In order to accomplish the extreme overclocking Japanese enthusiast Memesana, who published his results at XtremeSystems web-site, used ASUS P5WD2 Premium mainboard based on Intel’s i955X core-logic, Corsair PC2-5400UL 512MB memory modules as well as Intel Pentium 4 670 processor with stock speed of 3.80GHz. The processor system bus was overclocked to 1520MHz; processor’s voltage was pumped up to 1.70V, significantly higher than default setting; memory latency settings were CL4 3-3-4, memory voltage was set to 2.3V.

According to the posted statement, the system managed to calculate π (pi) number to 1 million decimal places in 18.516 seconds, which is currently the world’s record.

Earlier this year another overclocker has managed to push hit Intel Pentium 4 570J chip to 7.22GHz, but at that clock-speed the PC could function only in BIOS. The maximum speed at which he could boot Windows XP operating system and perform memory testing was 6.60GHz.

• XtremeSystems: Pentium 4 670 at 6925MHz – Bench-able. More than 7GHz Is Possible.
• X-bit labs: Intel’s Pentium 4 570J Processor Overclocked to 7.22GHz.
