Zotac GeForce 640 GT: Kepler for $ 100

The emergence of a new GPU architecture does not only make records in the performance of high-end graphics cards, but often changes the idea of what to expect from an inexpensive card with a low TDP. Let see what can offer GT 640 — associate member of the family Kepler



The lower segment of the GeForce 600 is already fully staffed. In retail, there are cards GT 610, GT 620, GT 630 and GT 640, and in the OEM- channels additionally supplied GeForce 605. But among all of them, only GT 640 can be called a fully new model, since it is based on the architecture of Kepler, and the remaining cards are a familiar model series GeForce 400 and GeForce 500 Architecture (Fermi) with certain minor modifications.


GeForce 640 is based on the GK107 chip, which previously debuted in accelerators GeForce 640M. The performance of the last was comprehensively studied on the laptop Acer Aspire M3-581TG: compared to the GeForce 540M new chip provides a very nice speed boost. GK107 contains one …

Red Dragon Radeon RX 560 2GB GDDR5 OC and Red Dragon Radeon RX 560 4GB GDDR5 OC from PowerColor

Not to lag behind other vendors the PowerColor company has presented a couple of Radeon RX 560 video cards. We should note that these cards utilize the renamed Polaris 11 GPU with 1024 active streaming processors. At the moment such accelerators are not available on sale, however they are to hit the market by the end of the month.



Thus, PowerColor has produced the Red Dragon Radeon RX 560 2GB GDDR5 OC, alongside with the Red Dragon Radeon RX 560 4GB GDDR5 OC samples, differing in the memory volume (which is observable from their names) and in the GPU frequency. The higher model’s Boost clock equals to 1,180 MHz, and the lower model’s rate is 1,288 MHz. The effective memory in both cases operates at 7,000 MHz.


Chilling of PowerColor specialties is ensured by a cooler with big heatsink. The auxiliary power connector is absent. The interface set includes DVI, HDMI and DisplayPort (x3).
