AMD launched the Radeon R7 240, along with its siblings, the R7 250, R9 270X and R9 280X in October 2013. The cards were all met with great fanfare. The Radeon R7 240 was designed to replace the venerable three year old Radeon HD 6570 and HD 6670 cards. On paper, it seems to do this quite well. While it does appear to be a bit slower than the HD 6670, it does its job using less than half the power of its predecessors.
We will be talking a look at the between level and inspecting the PowerColor PCS+ HD7850. The latest 7850 variation from PowerColor takes the reference design and tweaks it to be a better performer. This is due to the 140MHz overclock of the reference’s 860MHz Core Clock and the addition of the Memory being supercharger from 4800MHz to 4900MHz.
It will all come down to that last feature, one that no one else or very few will offer. In this case that feature will be the FleX option only from Sapphire. Just what is FleX? It’s being able to integrate at least three monitors to one GPU. We know just about all AMD cards can do that. But the fact is they can’t do it with having to go and purchase an expensive displayport monitor or buying an active displayport adapter which isn’t cheap either. With the FleX series you can do it without either. And that does for the card we will be looking at today, the FleX HD 7770 GHz Edition.
As of right now the Radeon HD 7750 maybe at the bottom of the performance chart but it does do well when it comes to moderate gaming and excel when it comes to digital video output and sound. Don’t let the placement of the card fool you. Sapphire’s newest 7750 have a nice advantage over the rest and it has nothing really to do with performance. The low profile HD 7750 is ideal for those that little space internally for larger cards. Yes, a great fit the many Dell and HP machine with the extra small enclosures and smaller power supplies.
ASUS is preparing a brand new graphics card based on Radeon HD 7850. Actually it has a lot in common with other, already released, DirectCUII models.
The ASUS HD 7850 Dragon Edition (DRAGON HD7850-DC2O-2GD5) has in fact lower clocks lower than DirectCU II Top model. Card arrives with 910/5000 MHz clocks for core and memory respectively. This is 65 MHz slower than Top model.
Probably the most distinctive part of this card is its protection back plate. A large copper heatsink is covered by dual 80mm fan DirectCU II cooling solution. What is worth noticing, is the fact that other DirectCU models have two heatsinks connected by heatpipes, while this model comes with a single one, with external heatpipes. Additionally, model is based on modified PCB with supper alloy power design, including 6+3 phases. It features a similar durability frame, known from Matrix HD 7970 model, which is basically the extra cover for components.
Card is equipped with the same memory size as all reference models – 2GB of GDDR5 chips. ASUS HD7850 Dragon requires two 6-pin power connectors. It features four display outputs, including DVI-I, DVI-D, HDMI and DisplayPort.
ASUS Dragon HD 7850 is already available in China for $361. There no information when will this model be released worldwide.

One thing that all the different models, from all the different manufactures have one common is that in order to run AMD’s EyeFinity 3 feature you need to either include at least one monitor that has a DisplayPort capability, or are using some type of adapter to convert DisplayPort into the connection your monitor supports. At least that is the case except for the model we are about to touch on today, the Sapphire FleX HD 7950 3GB, which can run this Eyefinity with all the monitors being DVI. How about that for saving a few dollars? And at the moment, this is the fastest Radeon card that can do that.
Now, we get to the point of this review we are conducting today. Below the GTX 670, NVidia has not bought anything new to the market. While AMD has the 78xx sitting in that upper mainstream realm. As of right now the older GTX 560 and GTX 560 Ti 448 Cores covers that area for NVidia until they release the GTX 660. Yes, the GTX 560 Ti 448 Cores is a little aged but it definitely still holds its hold when it comes to gaming. There is no game on the market that you can say this card will not give you a delightful gaming experience.
