@lambdaprog (the SDR# programmer) has also tweeted showing how well SDR# can run on a 10 year old i7 4700 laptop with the new performance improvements. With a huge 160 MSPS baseband IQ file, the software is seen to be using very minimal CPU.
So, how does #sdrsharp rev 1811 show in a 10 years old i7 4700 laptop with 160 MSPS input? The future looks bright, I tell you. #airspy pic.twitter.com/9nCcUjxe51
