Russia would definetly be poorer than in OTL.
Tsarist Russia had an average industrial growth of 5.72% between 1885 and 1913, and an overall economic growth of 3.3% per year between 1885 and 1913. Well it's not that bad, but not that great either.
On the other hand, according to CIA estimates, the soviet economy overall grew by an average 6% between 1928 and 1940 (that's allmost two times that of Tsarist Russia). Industrial production in the period 1928–1937 increased 2.5–3.5 times, that is, 10.5–16% per year (according to Stephen Wheatcroft, professor of the school of historical studies, University of Melbourne). Thats two to three times that of Tsarist Russia.
On total numbers, I'd suggest to take a look at this:
"The World Economy", published by the OECD.
Page 476
GDP of Tsarist Russia 1913:
232.351 million International US Dollar (1990)
GDP of the USSR 1930:
252.333 million International US Dollar (1990)
GDP of the USSR 1939:
430.314 million International US Dollar (1990)
That makes:
1913: 1.365 International US Dollar
(1990) per capita
1930: 1.501 International US Dollar
(1990) per capita
1939: 2.553 International US Dollar
(1990) per capita
Moreover, Poland (including western Ukraine and Belarus), the Baltics and Finland, the most developed regions of the Russian Empire except for Moscow and Petrograd, were not part of the USSR in the 20s and 30s. Thats a thing to consider, too.
Overall, as you can see in this statistic, total GDP and GDP per capita had allmost doubled by 1939 (compared to 1913). And that was despite WW1, the civil war and the loss of some of the most industrialized regions.
GDP is not a meaningfull indicator when discussing socialist states anyway. The main reason for that is that subsidies are not reflected in these statistics. And socialist states tend to not sell everything for the market price. Neccesities were heavily subsidized in the USSR, housing and healthcare was free. None of these are considered in the GDP data.
So the real economic progress from 1924 to 1939 was even more massive.
GNP is a way more meaningfull indicator for socialist economies. An even better indicator is NMP.
