Taking a look at the HD 4670, this is not the same HD 4670 we reviewed some months ago. This is a new and improved HD 4670 when has been packed with GDDR4, which is a technology jump from the GDDR3 on the older model. What we will be looking at besides the performance increase from the new memory is the new and quieter dual slot active cooler which sits atop the 750MHz GPU core. Sit back and read on as we take the new HD 4670 for a hefty round of tests.
The ATI-powered HD4830 from Sapphire is showing promise at being one of the best bangs for the buck cards out there. The HD4830 has the same amount of ram as the HD4850, but is clocked slightly lower and lacks a few of the shader units of the bigger sibling. Granted the HD4830 isn't here to steal any of the HD4850�s thunder, but it is targeted at the Nvidia 8800GT and 9800GT line. It is time to put the card to the test and see just where it stands.
This leads us to today's review sample which is the Palit 9800GTX+. The overall specifications of the 9800GTX+ are very similar to the 9800GTX with a few differences. The main difference is the reducing of die size. After months of playing second fiddle to AMD when it came down to die size Nvidia finaly got with the program and reduced their's to 55nm. This meant a few things to the consumer one being less power consumption. And for those that really like numbers higher clocks came along for the ride. How does 745/1100 sound? I figured you would lke that. Palit has a couple more features that will win you over if these first couple don't.
In the past few weeks we here at Pro-Clockers have reviewed all the latest ATI offering so we find it only fitting to review the HD 4850 X2, a card that I feel is "a little more fitting." The 4850 X2 is a dual GPU two gig of ram solution all on one PCB just like it's big brother the 4870 X2. And these are not enough numbers let me give you a few more. The clocks are preset at 625MHz on the core, 1000MHz for the memory and 800 stream processors times two. Enough of the preliminaries lets get into some testing.
The Sapphire HD4650 is a low price GPU based on the 55nm fabricated die that has all the features of the higher priced cards but just not to the extent of the others. Two of the main features of the card is the overclocked 650MHz core and 320 Stream Processors. This is more than enough to support your favorite high def video at a resolution of 2560x1600. And all this can be had for a mere $80.
As much as many of us would like to think so we overclockers/enthusiasts only make up a very small portion of the people that use a PC. I visit many forums including my own and so often we talk like we are the only computer users that matter. But if I had to guess what percentage of people are buying high frequency processors, crazy dollar amount video cards or coolers the size of elephants are very small about less than 10%. The other 90% are satisfied with a faster CPU than the one they had before or a video card powerful enough to play their favorite video games at a decent frame rate.
We got our mitts on the latest card to the Toxic line, the 4870 Toxic. And if you are one of those that have had a Toxic card before you haven't seen anything yet. The last Toxic we had here was the 3870 model that had a single slot cooling system based around the Vapor-X cooling system. While Sapphire took this Toxic in a whole new direction. This time the cooler coves the entirety of the card which is like the latest Nvidia lineup. I can't give you all the details of the new card in the introduction of the reviews so you must read on to find out more about the Sapphire HD 4870 Toxic.
