Review: Sapphire 7850 2GB OC Edition

An Introduction

A few weeks ago at CeBIT in Hannover, AMD announced their latest class of GPU models, the HD 7800 series.

Sapphire were kind enough to lend us the Sapphire 7850 2GB OC Edition for review. In this review I will be showcasing the possibilities of this card. I will be testing the card on games such as Battlefield 3, Dirt 3 and F1 2011. I will also be putting the 7850 to the test against several benchmarking tools.

First I want to talk about the GPU core itself. AMD claim the 7800 series’ new GCN 28nm architecture with its dual geometry engines and 9th generation tessellator will allow for a performance boost against the 6970 of up to 425% in certain scenarios.

The unboxing and what’s inside

Inside the box you will find:

  • 1x AMD Sapphire 7850 2GB OverClocked Edition
  • 1x CrossFire Bridge Interconnect Cable
  • 1x DVI to VGA Adapter
  • 1x Mini-DP to DP Cable
  • 1x 6 PIN to 4 PIN Molex Power Cable
  • 1x HDMI to SL-DVI Adapter
  • 1x HDMI 1.4a high speed 1.8 meter cable

The Graphics Card

The Sapphire 7850’s dual slot cooler has a stylish design to it. The first thing you will notice is that is has two fans. These low noise “Dual-X” fans are extremely quiet while idling at 20%; even at 80% they still seem very quiet. Below them you will see aluminium fins which connect to two copper pipes linked to the copper GPU block.

At the top of the card, you will spot a Crossfire connector supporting up to two 7850’s in a Crossfire configuration. Along the right side of the card you will find one 6 pin power connector. The 6 pin connector and the power through PCI-e provide the 130w required for this card.

Around the I/O plate you will see:

  • 1x Dual-Link DVI
  • 1x HDMI (Supports Stereo 3D + 7.1 Audio)
  • 2x Mini-DisplayPort

The GPU clock speed of Sapphire’s OC edition is set at 920MHz and the memory speed is 1250MHz. The reference card speeds are 860MHz and 1200MHz respectively. This is a big improvement in comparison to the last generation AMD 6850 which is 775MHz for the GPU clock speed and 1000MHz for the memory speed.

You can see the rest of the specs for the Sapphire 7850 OC Edition in the screenshot of GPU-Z below:


The test machine I will be doing these benchmarks on include the following components:

  • AMD Phenom II 955 @ 3.2GHz
  • ASUS M5A97
  • 2x4GB DDR3 DDR-1333
  • Corsair H50 CPU Cooler
  • OCZ Agility 3 60GB (Operating System)


  • Microsoft Sidewinder X8 Mouse
  • Microsoft Sidewinder X4 Keyboard

Operating System + GPU driver

  • Windows 7 Ultimate SP1 64-bit
  • AMD Catalyst 12.3

Benchmarking tools

  • Battlefield 3
  • Dirt 3
  • F1 2011
  • 3D Mark 11
  • Heaven DX11
  • Fraps

These benchmarks will be tested on the system above at 1920x1080 (unless otherwise stated). This graphics card will be put up against Nvidia’s 560 Ti OC Edition and see how they perform against each other.

Battlefield 3

The test included playing parts of the campaign of Battlefield 3 with “Ultra” settings at 1920x1080 resolution with 4xAA.

The card put up a great fight against the 560 Ti, Battlefield 3 ran extremely smoothly on Ultra settings with no noticeable tearing between frames.

Dirt 3

As with Battlefield 3, Dirt 3 will be benchmarked with the settings at “High” at 1920x1080 and 4xAA.

This time around there was very little difference in performance against the £170 ($280) Nvidia 560 Ti OC Edition. On average the Nvidia 560 Ti OC Edition performed better, although marginally.

F1 2011

F1 2011 was benchmarked with the settings at “Ultra” at 1920x1080 resolution with 8xAA. Here’s how it matched up against the Nvidia 560 Ti OC Edition.

As you can see from the scores above, the Sapphire 7850 OC Edition performed much better than the Nvidia 560 Ti. The 7850 was considerably better with the maximum frames per second. It would be interesting to see how the F1 2012 game performs with this card later in the year.

3DMark 11

I will be running 3DMark 11 in “Performance” mode. This test will be run at 1280x720 resolution.

As you can see from the benchmark above, the Sapphire 7850 OC Edition flies by with a 326 point lead.

Heaven DX11

For this last benchmark I’ll be running Heaven DX11 3.0. I’ll be running the built in benchmarking tool at 1920 x1080 with 4xAA.

I was impressed with the 7850 on this test. The Heaven DX11 is a difficult benchmark to score high on, and it gained a good FPS count.


The Sapphire 7850 2GB OC Edition is a great card, and gives the Nvidia 560 a run for its money. The performance on some games out performs most mid-range cards in its category. Sapphire has done some great work with the cooling system on this card, the “Dual-X” fans are nearly silent and the temperatures are great. The card idles at around 32◦c (90F) and goes no higher than 49◦c (120F) while running the benchmarks for a prolonged period of time.

I was impressed with the contents inside the box; most manufactures won’t put many accessories in with the card. Sapphire on the other hand decided to go all out and provide as many ways to get the 7850 connected. They included a Mini-DisplayPort adapter and a HDMI cable which could be a nice addition to those not expecting it.

Retailers are currently taking pre-orders of around £200 in the UK and $260 in the US, although the price is sure to fall as Nvidia release their competition to the AMD 7000 series GPU’s.

For those that go out and buy this card, It will be a good upgrade from an Nvidia 400 series or an AMD 5000 Series.

The Sapphire 7850 OC Edition is due to be released later this month.

Would you guys say this is the best card for this price?
Also, any educated projections on how much cheaper this will likely be a bit later this year? I likely will hold out to buy a new card until sometime between the releases of Diablo 3 and GTA 5.

What a sh@t OC one of the users on TPU has his purring along at 1350 core and 1450 memory the least Sapphire could have done was 1000/1300 for an OC

he gets an over P8000 score in 3DMark 11

Hmm, when the price goes down, this could be what I upgrade to from my 5770. Unless the new NVIDIA cards wipe the floor, that is.

I've got the 5770 and I have to say there is a HUGE bump in performance between the two!

As I said above, you may be waiting a while before the Nvidia cards are released.

Not bad! By the way, is it worthy to upgrade my GeForce 260GT to the 560GT or this ATI card?
I updated my GTX 260 (core 216) to the GTX 560 TI (384 core, last May) and it has been an excellent upgrade. Now, Nvidia has released the GTX 560 Ti 448 core. If that's in attainable in your price budget, it's a very good card, and comes close to the GTX 570.

I'd honestly say this card is better, the benchmarks above prove this . Also, Nvidia haven't even announced the cards yet so it will be a long time before the OEM's decide to ship them.
