okcpuid is an R package that gives some basic cpu information (clock speed, number of cores, etc.).
It's ok.

CPU Information

With the okcpuid package, you can get information such as vendor name, processor codename, and processor brand (outputs are only and example):

cpu_id()
# $vendor
# [1] "GenuineIntel"
# 
# $codename
# [1] "P-III Celeron"
# 
# $brand
# [1] "Intel(R) Celeron(R) CPU  N2830  @ 2.16GHz"

available processor instructions:

cpu_ins()
# $mmx
# [1] "present"
# 
# $mmx.extended
# [1] "absent"
# 
# $sse
# [1] "present"
# 
# $sse2
# [1] "present"

and cores, clock, and peak FLOPS:

cpu_clock()
# $ncores
# [1] 2
# 
# $clock.os
# 1826 MHz 
# 
# $clock.tested
# 2166 MHz 
# 
# $peak
# 17.328 GFLOPS

For CPU cache information, see the memuse package.

The Linpack Benchmark

okcpuid also has a benchmark not unlike the Linpack Benchmarker:

linpack(nmin=2000, nmax=5000, by=1000, warn=FALSE)
#    N      R.max
# 2000    13591178965 
# 3000    14043647701 
# 4000    14043647701 
# 5000    14312278293 
# 
# R.max:  14.312 GFLOPS
# N.max:  5000
# R.peak: 35.104 GFLOPS
