The exchange rate does of course have an impact. If it costs more to purchase from the source then the price to the customer has to rise. I'm not saying all of the price rises wholly exchange rate though but it's no myth.
This!
If I work in UK, Germany, Asia or USA. I pay the USD price for the product, so $600 for example, it cost me $600 no matter where I am.
So yes in defence, the USD cost does not change.
The impact on price is this:
$600 / 1.44 = £416.66 * 20% = £499.99 Inc. VAT
$600 / 1.27 = £472.44 * 20% = £566.93 Inc. VAT
The rates are the pretty stable rates we were getting from the bank pre-brexit (not the 1.49 peak) and the new rate is what the bank is offering now. Though around Christmas time the rate was over 1.50, I was ordering a lot of car parts from the USA and getting 1.52 rate from my cc company.
In short it is a 12-14% price increase simply due to exchange rate variance.
Yes some cards have increased more than this simply due to supply and demand.
Other cards and increased far less than this as we simply reduce our own margins to single digits because supply is very good or to be competitive.
Another example, Palit 1080 FE is £599 Inc. VAT on OcUK, think makes us the cheapest, based on my re-buy yesterday our new sell price will be £650 when fresh stock lands. Why, exchange rate!
Our cost in USD is un-changed, some like Zotac on 1070's have tried to give us a little lower cost in USD but it is like $5-$10 saving to help keep our prices low.
But the simple fact is the exchange rate variance is causing a 12-14% increase which is above our normal margins we'd make on components, this is why many 1080 pre-orders from pre-brexit are shipping and making us losses.
Unfortunately in components margins are slim, a lot of the time single digits, we use other products such as peripherals, systems and labour services to improve our overall margin.
