AMD Radeon HD 6670, HD 6570 and 6450
I know that being fashionably late sometimes can be fun, for this review we received the cards hmmz, half a day before launch. So please forgive us the 'quick' review where we dive into the basics only.
Two weeks ago we already brought you a quick overview of the entry level Radeon HD 6450, well guess what ? AMD has more on the table. Three cards are now officially released in the low-end segment, namely the AMD Radeon HD 6670, HD 6570 and 6450.
All small, cute and tiny products that have been released by AMD to address a sizable market.. Products that could be handy for desktop usage and hey now, it might sit mighty fine in a HTPC.
The Radeon HD 6400/6500 and 6600 series addresses the low-level market yet AMD has decided to double the number of stream processors available to the Caicos (6400) core over previous products and Turks for the 6500 and 6600 series. All these cards come with:
- Graphics core DirectX® 11
- Eyefinity displays Up to 3
- Low Board Power
- Frame Buffer 512MB-1GB
- Memory Type GDDR5/DDR3
- Available Display outputs HDMI 1.4, DP 1.2, DVI, VGA.
- Form factor Low profile
- Thermal Active or Passive cooling
The three low-segment series 6000 cards"
Radeon HD 6450 -- All the graphics card have a 40nm based GPU and start at a very decent 160 SPs, as well as 8 texturing units, 16 Z/Stencil ROP units and 4 color ROP units for the 6450. The clock frequencies will vary based on models, ranging from 625 towards 725 MHz. The card can now be configured with faster GDDR5 memory, AMD is now allowing for up to 1GB of GDDR5 video buffer to be installed that can be clocked between 800MHz and 900MHz. The TDP is 20W for the DDR3 models adn 27 Watt for the GDDR5 models.
Radeon HD 6570 -- All the graphics card have a 40nm based GPU and start at a very decent 480 SPs, as well as 24 texturing units, 32 Z/Stencil ROP units and 8 color ROP units for the 6570. The clock frequencies will be 650 MHz. The card is configured with faster GDDR5 memory or could as well be equipped with DDR3 memory, AMD is now allowing 512 up to 1GB of GDDR5 video buffer to be installed that can be clocked between 800MHz and 900MHz. This card will have a 44W TDP.
Radeon HD 6670 -- All the graphics card have a 40nm based GPU, the transistor count for his model is 716M and is comes with at a very decent 480 SPs, as well as 24 texturing units, 32 Z/Stencil ROP units and 8 color ROP units for the 6670. The clock frequency will be 800 MHz. The card is configured with faster GDDR5 (4000 MHz effective) memory, AMD is now allowing 512 or 1GB of GDDR5 video buffer to be installed allowing it a 64 GB/s bandwidth. This card will have a 66W TDP.
The Radeon HD 6670 is the card we'll briefly review today.
We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.
Gigabyte Radeon HD 7790 2GB OC review
We test and review the Gigabyte Radeon HD 7790 2GB OC edition, also known under SKU code GV-R7790OC-2GD. We benchmark the product incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming. The Gigabyte HD7790 OC 2GB clocks in at 1075 MHz on the boost engine, packed with totally silent custom cooling.
Radeon HD 7990 review
We review the new AMD Radeon HD 7990 including FCAT frametime measurements. The dual GPU product that you guys learned to know under codename Malta finally is released. AMD it doing it in style, two fully equipped Tahiti XT2 GPUs versus good yet silent cooling. In this review we'll look at the product, the architecture, the benchmarks, including frametime based FCAT measurements. Head on over towards our AMD Radeon HD 7990.
Club3D Radeon HD 7870 Joker review
We test and review the Club3D Radeon HD 7870 Joker, this is the much discussed 7870 card that in fact has a 7900 series GPU, the Tahiti LE. For a fair amount of money this series 7800 product now offers 7900 series performance. Armed with 2GB of graphics memory it hits a sweet spot gaming performance wise and to date it one of the more popular products in the mainstream segment. Let's check out the Club3D Radeon HD 7870 Joker.
