Nokia RM-1027 visits the GFX Benchmark site; device could be the unannounced Nokia Lumia 53021
This could be the Nokia Lumia 530 that we told you about in March. That model is expected to be the replacement for the Nokia Lumia 525, which itself took over from the Nokia Lumia 520. The latter is the most popular Windows Phone model ever sold, thanks to its perceived value.
The Nokia Lumia 530 is code-named the Nokia Rock, according to evleaks, and so far we have no idea when this model will see the light of day. Until the phone is released, you might want to consider the Nokia Lumia 525. This model has the same specs as the Lumia 520, but doubles the amount of RAM to 1GB, allowing it to support more games and apps from the Windows Phone Store.
